My apologies if you have discussed this previously and I missed it but this is an important topic that everyone can benefit from.
How fast do you believe most coyotes are running, in MPH, that are running away from you AND WHY do you believe that?
Are you guessing or do you know for sure?
If you don't know for sure, don't answer. If you've ever timed their speed by how far they traveled in a certain amount of time, I want to hear your answer.
I'm not talking about coyotes you are chasing with a pickup or coyotes that are kicking it into high gear to beat you across a road. Naturally each of those situations will result in more speed from the coyote. I'm talking about most coyotes in OPEN COUNTRY that are running away from you after the shot most of which will be running at a 45 degree angle or less.
Why do I ask?
Because Tom Schimd recently sent me an excellent article on leading running coyotes which is something I had previously discussed with some of our other ADC trappers and I'd like to get a better handle on leading running coyotes at various angles and speeds.
For leading a running coyote the formula is: Time of bullet's flight in fractions of a second, times the coyote's speed (in feet per sec. FPS) which gives you the lead (in feet). Change yards to feet; change mph to fps: 35 mph X's 1.466 = 51.33 fps target speed. At 150 yards, bullet flight time, .144 of a sec X's 51.33 fps 'right angle' deer or coyote speed = 7.4 foot lead ahead of the chest, or about one deer length for the 'vital kill zone fron half' of the trophy buck.
Swing through the middle of the body and center of the neck, squeeze off your shot when the lead looks right, and be sure to keep swinging, -- follow through! Then witness them dropping in their tracks, sometimes before your scope's field of view.
MPH to FPS conversion: [MPH times 1.4666 equals FPS]
Coyote @ 200 yards moving @ 20mph / 29.3 fps times bullet flight time of .166/sec = 4.8 foot lead ahead of the vital target area. This is using the .243 Win., Nosler bullet with Ballistic Coefficient. .276; bullet flight time is .166 of sec.//coyote running only 20 mph = 29.33 fps x .166 of sec., = lead 4.8 feet or less than one coyote length in front of the vital rib cate target area.
Here is the breakdown of MPH to FPS conversion for various coyote speeds....
35 MPH = 51.3 FPS
30 MPH = 44 FPS
25 MPH = 36.6 FPS
20 MPH = 29.3 FPS
Bullet flight time of 3700 fps = .162/sec @ 200 yards. 3700 fps bullet velocity / 600 ft (300 yards) = .162
Coyote @ 200 yards running at a 90 degree angle moving @ 25mph / 36.6 fps times bullet flight time of .162/sec = 5.9 foot lead.
If that same coyote was running at a 45 degree angle, how much would it change the lead?
Would it be half (3')?

No. Useing your numbers and if my math is right it would take 4.1 feet of lead to get you on fur.

Pretty complex math to do while in the intuitive act of swinging a rifle on a coyote. With moving targets, using the tables should provide some fun and valuable practice.
Chasing coyotes with a vehicle is outside of your query but it does give an idea of max speed. I’ve run over and killed two that tried to outrun me down a smooth dirt road. As I recall all it took was 35 mph to kill the one I clocked, so he wasn’t going quite that fast, though I’d chased him about 75-100 yards by then and his initial burst may have slowed, or he may have been a slow individual. I’ve clocked jack rabbits top end from 37 to 45 mph, so different individuals have different top speed, as we’d expect.
I rarely shoot at a running critter anymore, but none of the formulas worked for me when I did. Apparently my intuitive style is to swing faster because I’ve hit coyotes, elk and deer when they were on a dead run and always hit exactly where the bead or the cross hairs were when the sear broke. When I consciously lead, I shoot in front of the animal. Others, who are better shots than I am, consciously lead animals. I asked an expert shot about it and he said that I was swinging fast enough to give the right amount of lead, and not to think it through too much nor change as long as it was working.
I shot at several animals with a recurve bow, instinctive shooting, and was pleasantly surprised that without thought, the arrow and the critter would arrive at the same spot. I simply looked at the critter and shot at him, whether he was standing still or moving. On one running coyote, as the arrow left the bow I gasped at how far ahead of the animal, maybe 25 feet, the arrow was headed. At the release it seemed way too far ahead but they converged perfectly.
Your calculations are interesting and useful, and I've copied the formula and table. The brain is a pretty good computer for calculating lead however, if we practice enough to calibrate it. I don’t practice enough and prefer close shots at standing critters so I pass most other shots nowadays.
An anecdote on un-lead: A coyote broadside at 110 yards, trotting slowly. With a 6mm Remington and 75 grain bullet I put the cross hairs on his shoulder and consciously swung through till I was even with his nose (I was in my experimental stage of leading) and decided that was too much lead for his slow speed. I eased it back to below his ear and fired. I hit him in the hips. I think the bit of reverse swing as I moved the sights back accounted for the hit far back, even at the coyote’s slow speed.
Posted by Leonard (Member # 2) on April 08, 2007, 10:22 AM:
It seems to me that a coyote running away from being shot at; the circumstances do not allow you to "clock" him? But, my guess is about 25MPH after the first shot, but they seem to have a little left after the second close miss.
I doubt they do over thirty miles per hour, except in the extreme example above where they are being chased by a vehicle, or grayhounds? That seems to me, a different catagory, and in that case, even Scott might get up to 30MPH? Desperate times call for desperate measures.
Good hunting. LB

I'll remember to swing!
For me hitting a running coyote always amounts to luck. I don't shoot at enough coyotes to of subcontiously figured out the distance, lead, and swing thing.
I do find it interesting though that after shooting lots and lots of trap and flying birds, I've somehow managed to calculate distance, lead, speed, swing etc. subcontiously. Neat how our brain figures out all that stuff without ever really having to do the math.
I have been lucky though. Twice on coyotes. Both times my buddies told me it was awesome shooting. Yeah right!?!? I just saw how far my bullet was hitting behind and made adjustments.

The first one I was a teenager and I don't remember much of why other than to see if I could.
The second one fur prices were sky high and I wanted his hide. It was dark, on a winding lane with hedge thick thorn bushes on both sides. Fair pelt on that one that I dimly remember bringing $145.
It is a curious thing that animals will often run down a road in front of a vehicle when they could easily escape if they jumped off of the road. Jack rabbits, coyotes, bear and moose are especially prone to run on the road. My theory is that they know they can run faster on the road than they can in brush and broken ground so they stay on the road. Go easy if you ever get a moose in that situation as they have been known to kick a hoof through grill and radiator.

Well Higgins, I can't say why exactly, but I did it once, myself. It gave me a large measure of satisfaction. I had always wondered why so many road kills and it had never even come close, for me? It had eaten at me for years. Like Lee Marvin said: "It was so fine" (Cat Ballou)

Now THAT's funny!
On a more serious note, I saw a fairly recent photo of Scott and I don't think he could run that fast anymore.

Fine figure of a man yes, but 30-35mph?
Posted by TRnCO (Member # 690) on April 08, 2007, 03:26 PM:
One piece of the puzzle of hitting something running that isn't in your equation is the fact that you figures are probably using a stationary rifle barrel as opposed to a swinging rifle barrel, or vasa-versa. The lead needed with the two different shooting techniques will be different!
Posted by TA17Rem (Member # 794) on April 08, 2007, 04:31 PM:
Scott may not run 30 mph. but he sure can cover alot of ground. Reminds me of the young caller and the old coyote caller. The young caller says lets run down the hill and get us a coyote, the old caller replies, "Lets walk down and get them all"
Posted by Wiley E (Member # 108) on April 08, 2007, 08:09 PM:
TRnCO,
Go back and re-read the post. It specifically talks about a swinging lead.
What will affect this to a small degree is that I used muzzle velocity when I would need to use an average velocity between muzzle velocity and velocity at the target. It wouldn't make too much difference.

Instead of listening to the pastor this morning, I was thinking how easy it would be to clock running coyotes by picking out an object such as a fence and when the coyote ran by it, start the clock. When they reach another distant distinct object, stop the clock. Range the distance between points and calculate the speed. Enough of these and I could come up with a pretty good average.
From that point it's a matter of figuring leads for various angles.
Once a person has a basic understanding of these leads, it can become instinctual.
I missed a coyote this year that was running at about 20 mph at 150 yards. I led him about 1 foot. I shot in front of him 1 foot because he was running with a 20mph wind. Never thought about not having to lead when the coyote is running with a wind that is as strong as it's speed. That's when I committed myself to understanding leads and I will figure it out.

Scott on a an engineering aspect a lot of the decimals past one digit are going to be negligble becasue they aren't going to make a difference besides making your math more difficult.
First are you referring to 90 degrees being straight away or perpindicular to the shooter.
If straigt away from the shooter then
you have to do a little Trig but a coyote running straigth away is going to be at a more constant yardage (getting further away at a slower rate)
It is not as easy as just dividing the lead by the fraction of the angle difference (45/90)= 1/2
Also you have to look at the angles and the size of the target changing so the lead is slowly going to go from in front to over the top of the coyote besided in the straight away scenario
I have never clocked any coyotes or timed them so i won't say but there is enough professional people that have done it that you can look up to get an average i'm sure

nd,
Don't confuse the confused. This is as if you were sitting on an East/West road and a coyote ran across in front of you heading from the North to the South at top speed on a flat piece of ground. I'm not going to fog this excercise with angles just yet. The math is correct.
Here is the fps conversions for bullet speed at various yardages with 3700 ave velocity.
50 yards - .041
100 yards - .081
150 yards - .122
200 yards - .162
250 yards - .203
300 yards - .243
Here is the leads for the above shot at various coyote speeds.
35 mph or 51.3 fps
50 yards - 2.1'
100 yards - 4.15'
150 yards - 6.26'
200 yards - 8.36'
250 yards - 10.41'
300 yards - 12.47'
30 mph or 44 fps
50 yards - 1.8'
100 yards - 3.56'
150 yards - 5.37'
200 yards - 7.17'
250 yards - 8.93'
300 yards - 10.69'
25 mph or 36.6 fps
50 yards - 1.5'
100 yards - 2.96'
150 yards - 4.47'
200 yards - 5.97'
250 yards - 7.43'
300 yards - 8.89'
20 mph or 29.3 fps
50 yards - 1.2'
100 yards - 2.37'
150 yards - 3.57'
200 yards - 4.75'
250 yards - 5.95'
300 yards - 7.12'
There you go if your average velocity is 3700 fps.
If a coyote is running 25 mph and crosses in front of you at 200 yards, the lead is 6' for a bullet traveling an average speed of 3700 fps. The math is correct. If you don't like the decible points, round it off.

Wiley E,
I think you are trying to make this a lot more difficult that it needs to be.
Some things in life can be learned, but not taught.
There are just too many variables to hitting a running coyote.
Your eye needs to learn to communicate with your brain which needs to communicate with your finger.
When a coyote is running, you don't have time to determine his range, angle, speed, time of flight for the bullet, wind deflection and everything else. If you try to figure out all of that, the coyote will be long out of sight before you are ever ready to fire a shot.
You eye needs to recognize a sight picture and send the signal to fire to your finger before the sight picture changes.
This is one of the places that a rifle with low recoil and a fast projectile really shine, when you do miss, if your eye can pick up the impact, your brain will make the adjustments, and give a new preferred sight picture for the eye to seek.
It's interesting that you would ask such a question.
Posted by Wiley E (Member # 108) on April 08, 2007, 09:30 PM:
Tim: "I think you are trying to make this a lot more difficult that it needs to be."
I knew that was coming........
That's what they said to the guys using range finders and turret knobs but anyone who has used both of those tools will tell you it has greatly increased their long range shooting ability.
I'm looking for a starting point to get these numbers in my head just as I do with windage and elevation numbers. It's no damn different.
Nobody is saying that you need to take these numbers to the field and calculate them or that you would even have the time. I'm simply trying to get the general idea of correct leads in my head for an average coyote speed at varying distances. Nothing more, nothing less.
Interesting that I would ask this question? Why is that Tim? Is there a point you'd like to make? If you have something to say, say it!
I've never pointed a radar gun at a coyote running away from me, have you? I have an idea of how fast they might be going based on the many I have chased with a pickup but I was curious what others thought the average speed was.
More interesting that I would ask the question is your inability to see the value in these equations. I guess when your average running shot is 50 yards in heavy cover, the value might seem quite limited. For those of us who call a pile of coyotes in open country, there is value in this.

I didn't offer a guess, because I don't think that a number that correlates to a coyotes speed is pertinent to learning to shoot a running coyote.
But if I had to venture a guess, I'd bet that some coyotes can hit speeds of 45 MPH for short distances.
Turrets and range finders are great tools for long range shooting, but useless for running coyotes. By the time you need those tools, you need a stationary target, and time to consult a drop chart.
When the coyote is running, you don't have time to consult, you only have time to react.
Why would you want to create a ballistics chart that you won't have time to consult?
Do you shoot running targets with a stationary rifle, or have you found a ballistic program that also takes into account the speed at which the angle of the barrel changes?
It sounds like you are trying to teach yourself to fail. It would be virtually impossible to create a chart such as you are asking for. But then you already know that, and that's why I find it interesting that you would ask.
Posted by R.Shaw (Member # 73) on April 08, 2007, 10:04 PM:
A swinging shot on a coyote pretty much rules out using a bipod, sticks, sitting on the ground or sitting on a stool. You must be standing and the coyote needs to be in the open for a short time.
A running coyote at 200 yards or less requires no lead if you are swinging the rifle. I follow the coyote a short distance with the crosshairs where I want to hit him and then use a controlled jerk along with a slight push or pull on the rifle . If the coyote is really moving, I will follow with the sights on his head because it is in line with the rest of the body. You get a little built in lead so to speak and some are hit right there in the head too.
A heavier rifle works a little better because once it is moving it takes a little effort to stop it. Keeping the gun moving during and after the shot is what makes this method work.
Randy
Posted by TA17Rem (Member # 794) on April 08, 2007, 10:51 PM:
I would have to agree with what Randy has said as far as how much lead. Most shots would have to be in the standing position. I have used the shooting sticks made by E.L.K. products and find that they can give you enough room to swing the rifle for a running shot and if i had a choice i would rather use them than do it free hand..
I can see where Scott is comeing from, and i have used a ballistic chart on my rifle and then later i switched to the Kenton BDC dial.
When i see the coyote comeing i take a rough guess at the distance of the coyote and dial it in. For under 600 yards at a running coyote the distance dose'nt have to be exact, just close. For elavation you have 6-8" to play with and and the length of coyotes body for lead and windage.
Like Tim B. stated once you have the site picture in youre scope then you squeeze one off, and if the rifle is low on recoil you can see where you hit and then make the adjustment.
This is one of the reasons i like to use my 17 rem with the high stock comb. When i'm calling or hunting coyotes i always set my varible scope on 10X, no matter which rifle i use. I get the same site picture every time. By not useing the BDC method youre guesses change from shot to shot. What i mean is how much was the correction you made by guessing, its tuff to tell the difference between a 1-1 1/2 ft correction.

There simply can't be a formula for running coyotes. No two coyotes are going to run the same speed and they are rarely going to be at the exact same angle. Can't be done Scott.
Posted by Wiley E (Member # 108) on April 09, 2007, 06:01 AM:
TB: "Turrets and range finders are great tools for long range shooting, but useless for running coyotes."
Again, you missed the point Tim.
My point was that leading running coyotes, by understanding bullet speed and coyote speed at varying ranges, is just as important as understanding windage and elevation.
You don't have the time to calculate wind speed and distance with every running coyote either but if you have an idea how far the coyote is (400 yards) and how hard the wind is blowing (15mph), you have a better chance of hitting your target.
Same thing on a running coyote. If you guess a coyote is traveling at 25mph and you guess it's about 250 yards away, the lead is 6'. You adjust more or less accordingly.
TB: "When the coyote is running, you don't have time to consult, you only have time to react."
TB: "Why would you want to create a ballistics chart that you won't have time to consult?"
(Heavy sigh..........)
NOBODY SUGGESTED YOU WOULD HAVE THE TIME TO CONSULT EXACT CALCULATIONS.
In most situations your first bullet tells you where to lead with your next shot. Unfortunately, you can't always see the hit.
If you have a general idea in your head of distance and speed and angle, you would know how far to lead if you have a general idea of those leads. These charts provide a general idea of those leads. This estimate of leads becomes part of your sight picture. That is the only purpose in presenting this information.
If a coyote crosses the road in front of me at 200 yards and he's running about 25 mph, the lead is 6'. You store that away in your memory.
TB: "It sounds like you are trying to teach yourself to fail."
My history would prove otherwise.
Nobody has time to consult lead charts with flying birds at all angles and ranges either do they? Those who have a basic understanding of leads make those leads part of their sight picture.

This is nothing more than a mental excercise to understand various leads as a starting point. Nothing more, nothing less.
I'm not so damn stupid to think I would have the time to calculate coyote speed, coyote distance, and angle on every running coyote.
Why doesn't someone tell me I need to chamber a round before I can shoot?

Not so. I never use a bipod, and it is rare that I even use shooting sticks, but every running coyote I have killed was shot while I was in sitting position. I almost always call from a sitting position. No time to stand up just because the coyote won't stop for the shot.

Why do you have to shoot them. Whats wrong with running them over. I cought a coyote in a playa one day clocked him between the 32 and 34 marks on the odom. before I lost him under the bumper. I didn't hit him though, he took a sharp right before the tire hit him. By the time I slowed and turned he had the edge of the playa and was up the side of the hill without missing a stride. Thats fast!

Anyone know the BC and SD on my 1500HD Crew Cab. At 88ft\sec I'm having a hard time with the lead.
Usually end up in the ditch.
Last year I did get lucky on a family of 5 coons. lead them just right and managed to get 4 of them. That paid out to 32.00 Edit: I might add that two were DRT right there. The other two I had to finish off with a couple of bonks on the head with a baseball bat.

Scott, I think your heart is in the right place, especially for those that don't have a clue where to start. For somebody that has flung lead at a few coyotes, when he reads "twelve feet!" that should give him something to go on?
But when we look at trapshooting, for instance, it still takes a lot of concentration and instinctive lead to break 25 straight, rather than charts and formulas.
There is no substitute for experience and practice and a semiauto.
Good hunting. LB
edit: the club I belonged to used to have a bunch of shooting events at the annual campout. Mostly different target shooting, score or group size, but one of the most popular was the running fox shoot. We rigged up a wire down a hill with a plywood archery fox cutout glued to the front and suspended on eyebolts. You could only fire between two parameters, trees would obstruct the rest of the run, start and finish.
You would be surprised how many of these seasoned coyote hunters would miss the target completely...mostly behind it.

I've been trying to think and construct a good target to recreate running coyotes but haven't come up with much that would be cost effective. That one sounds pretty good Leonard now i just need a hill!
practice is the only real good way to get better at those shots but it is tough to practice that one without the right set up

Wiley, it is very important to chamber a round before you shoot. Why wouldn't you think that was good information?
I never said that you would have time to consult anything, just that there are too many variables to have a pat answer in your head for how much lead. It just becomes instinctual after shooting at a few hundred and hitting a few. I have gotten better at running shots at a quarter away angle but still have a tough time with a straight across running shot. The speed changes with each shot. I have done better since I have packed an AR alot. With my 204 AR there is virtually no recoil and I can generally see any misses and correct if needed and just keep swinging and pulling the trigger. And I agree with Rich C. about shooting sitting. I rarely shoot any other way and shoot plenty or running coyotes. I like the Vern Howey bi-pod for that reason.

If a person is right handed and sitting on the ground, a coyote running from right to left could be killed from this position. You are shooting across your body, it is comfortable,and the rifle remains in good contact with your face at all times. From the sitting position a coyote running from left to right would be a different story, at least it is for me. I haven't figured out how to make all of them run right to left in order to shoot while sitting on the ground.I use a stool and it is pretty easy just to stand up and position myself for the running shot from any direction.
I have tried lots of times to shoot a moving coyote while using sticks. My motion is not fluid and it is impossible for me to keep the gun moving after the shot. It always seems I am going into a twist of some kind that binds me up. The sticks work fine on a straight-away runner. But again, they all don't run straight away.

Randy, the cradle that holds your rifle on the Howey bi-pods swivels. Makes it smoother. But i have used plenty of the others also. There is alot of movement there before they bind. (Except for the Harris type bi pods, they suck for running shots)
Posted by Leonard (Member # 2) on April 09, 2007, 01:27 PM:
You make an excellent point, Randy. A coyote running to my right is not in very serious trouble, depending on which way I am sitting.
I have a stoney point bipod that swivels just about any position, and tilts... but the drawback is that the upper part, which detaches from the sticks, is setscrewed to my sling swivel, and I had to take the stock apart to install it. That's no big deal, but it does limit me to that one rifle.
Good hunting. LB

edit: take a look at this pic and think about another thread where the discussion is about shooting coyotes in order of preference. You can see how easily the nearest coyote can disappear while you center punch the one just emerging from the brush.

I went out today to shoot some targets and give you an idea of how The BDC dial i have been useing works. First off i'm not claiming to be a better shot than Dan C. or anyone else. What i did was set up a target at 500 yards. I dialed the scope in for 500 yds and fired two sighters. both bullets hit to the right of target so i adjusted the windage 4 clicks and shot two more sighters and missed the target completly and to the left. I took away two clicks and fired two more rounds and was right on target. I then fired five rounds for effect. The width of the target is 16", if it would of been a live coyote he would of been put down even with the 4 wind correction shots. I used to use the traj. tables taped to each rifle and i could glance at it for a referance, it was too much for me to remember all the time. With the BDC dial all i do is dial and smile. If i'm off target a bit i can correct it by changeing the sight picture a little and still be-able to hit the target..The Kenton company makes a windage dial also and that is next on my list.. http://i48.photobucket.com/albums/f208/TA17Rem/IMG_0620.jpg[/IMG]]

Wiley, I realize your very first post says how to swing through a target before firing, and continue swing through after firing, BUT your math computation doesn't compute for rifle swing through, does it? Your math is figuring bullet speed, distance, and how fast your target is moving. But if that bullet is leaving a swinging barrel, the lead will be less than if the barrel is stationary, such as your figures are using.
There are three shooting techniques that we have to choose from, and depending on which a shooter uses, your math numbers could vary. How much? Don't know. Maybe not enough to loose any sleep over. But if a guy is going to go through all the trouble of getting all these leads at certain distances in your head well enough to use in the moment of battle, why not have the correct numbers in your head!
The difference in lead between the 3 shooting techniques, I would guess, could be as much as a few feet at 200 yards! Maybe not!
I've found one of the best ways to kill a runnung coyote is to have your partner be watching through his scope and call your shot, and then your partner waits for you to cycle and regain the target before he fires so you can call his shot. As was said, if you don't see where you hit when you missed, there's no way to correct, since you don't know what you did wrong to start with!

Sorry TRNCO, but you are not correct this time. The bullet does not know if the barrel is swinging or not. It is the very instant that bullet leaves the bore which makes the difference.
Posted by tlbradford (Member # 1232) on April 09, 2007, 05:11 PM:
Wiley, I think you are looking at this from the wrong perspective. You started this with calculations of a coyote running straight away. This has too many variables to be that useful for a starting point. I think this excercise is more useful for a coyote running perpindicular to the shooter. By eliminating the fact that the coyote is getting further away at a fast rate of speed, you are eliminating a variable. The information you posted would be much more helpful to a coyote moving perpindicular, because you have a constant distance to the target, for hypothetical purposes a constant speed of the coyote, and the calculations will give you a single measurement for leading. The math is easier and I would venture to guess that most people miss this shot with regularity.

I talked with a friend today who has clocked a few coyotes running parrel to the road. he said that he had one go as fast as 40 and two others around 35 mph. He stated the one going 40 was in a bean stubble field with only a inch or to of snow on the ground.

TRnCO,
Great post! This is the thought process I was looking for. A general idea of lead.
You could be right and I was thinking about this very thing after Randy Shaw mentioned "jerking" the gun forward.
RS: "I follow the coyote a short distance with the crosshairs where I want to hit him and then use a controlled jerk along with a slight push or pull on the rifle"
A controlled jerk and push or pull would change the aiming point as compared to a smooth swing staying at the correct lead in front of the coyote.
Leonard: "You would be surprised how many of these seasoned coyote hunters would miss the target completely...mostly behind it."
I rest my case!
I like that picture Leonard. It looks as if you are saying, "how the hell does anyone expect to call a coyote with this thing". LOL!
Here, let me make a few readers happy here, I'll rain on my own parade.
These leads are for a coyote crossing in front of you ONLY. Since most coyotes on the calling stand are running away from you at various angles and I don't know how to figure those angles, you can run a copy of this off and wipe your ass with it. Does that help?
I guess I'm back to guessing and watching my bullet again.

What would the difference be between someone throwing something out of the window on a moving vehicle and a bullet leaving a moving barrel? Other than one would be more obvious and more easily observed?

Some of you may not realize but when you aim dead on, a moveing coyote and you follow through with youre swing you are forgetting the time of bullet flight. For an example if you aim for the shoulder and follow through with youre swing, by the time the bullet gets to the coyote its not going to hit where you aimed, The bullet will hit farther back depending on the distance of the coyote and his speed, or will end up in a miss.
You are following through with the swing and when you fire the coyote is not going to be where you are holding when the bullet leaves the barrel.
And like Scott said you will need a 6' lead when coyote is running left to right.
Some one can do the math: you need the bullets flight time from gun to moveing target at 200 yds. The speed of target 35 mph. moveing from right to left.
Once you get the idea into youre head (site picture) of how much lead is needed and some live practice, you will have increased youre hit to miss ratio.

Wiley,
I am surprised that you didn't pick up on my observations regarding whether or not a rifle barrel is swinging at the moment that bullet actually leaves end of said barrel. I contend that it is NOT the swinging barrel that determines where the bullet strikes. At the very instant in which bullets exits barrel, it won't matter a whit if said barrel is swinging with the target or not. It is the delay between the moment the sear breaks, versus the moment the rifle actually goes BANG which makes sustained lead or "swing through" necessary.

Numbers schmumbers. Math my ass. Doesn't anyone just go out and shoot a thousand jack rabbits a year anymore? Actually, I don't have time for that anymore, myself... But, back when I was shooting 20,000 to 30,000 rounds a year at critters, after a full summer of shooting at running jack rabbits, running coyotes just seemed really huge and really slow and really easy to hit.
Note - I'm not nearly that good anymore. Use it or lose it type deal, and I just don't get in the massive trigger time anymore. These days, I'm probably no better than average.

Like posted before hitting running targets consistantly takes practice and the ability to retain the knowledge gained and instantly put it back into the similar scenario again at a blink of an eye. Repetitive motion on instinctive reaction.Easy for some not others.

Posted by TRnCO (Member # 690) on April 10, 2007, 04:48 PM:
You may be right Rich, But I'm going to speculate a little more. What if I took a shotgun and got 30 yards from a patterning board and fired just as I past over the board while swinging from one side to the other. I would expect my pattern to be oval shaped, would it not?
Maybe the higher speed of a rifle takes the swing out of the equation, hell I don't no!
Posted by TA17Rem (Member # 794) on April 10, 2007, 06:51 PM:
If its one continues swing and you pull the trigger as you pass the target, you will only hit half or none at all.
Like Rich said you have to figure the time it takes to pull trigger and have it strike the shells primer. (This is called lock time)
And then you have to figure time of flight. (How long it takes projectile to travel from gun to target)
Every year i take more running shots at coyotes and every year i get better at it. In order for me to be more consistant on my running shots there are certain things i have had done to my rifles to help increase my odds and i will list them.
1. Trigger; I use a custom trigger that dose'nt have alot of play in it and the release is crisp.
2. Fireing pin, I use a David tubb fireing pin. The fireing pin is lighter and faster, which speeds up the lock time. (time it takes for the fireing pin to move foward and strike primer)
3.Scope; I use a scope that has a 30mm tube. gives you a litte better site picture or a scope with larger bell lens also helps. I set my scopes 0n 10x when makeing running shots. By doing this it helps to get the same site picture each time.. Repeatability!
4.Stock; My stocks are cut to my length of pull and i use a brand or style i feel comfortable with. Stock comb; I use the sako style hunter stocks or mount a cheek piece on one that don't have it. Whats the purpose? when shooting a rifle you want youre head straight up and down as much as possible, not leaning over the stock. Also with the sako style comb you have a flatter area to rest youre face against. Repeatability!
5.Cartridge; a cartridge that is fast with a bullet that has a good B.C. and low to med recoil. For example a 223 imp., 17 rem with a 30 gr. bullet,22-250 imp., 243 imp.. The faster the bullet the shorter the time of flight is.Most of the cartridges i listed will push a bullet along at 3700 to 4200 fps.
6. Barrel; I prefer to use a barrel that is 24-26" long with a number five contour. Not too heavey and not to light.
7. Practice, practice, breeth control, squeezeing the trigger, and follow through.
What i listed is'nt necessary for killing coyotes, you can get by with what you have. But if you are serious about it like i am, you will do whats needed to increase youre chances of makeing those running shots and even the long range shots.
Posted by TRnCO (Member # 690) on April 10, 2007, 06:56 PM:
So, answer the question then, will the pattern be oval shaped, assuming I pull the trigger at the given moment needed to put the pattern on paper?
Posted by Leonard (Member # 2) on April 10, 2007, 07:25 PM:
Maybe? If you could swing it at 80 MPH? Otherwise, it is just going to affect where it was pointed when the shot column left the barrel.
Good hunting. LB
Posted by R.Shaw (Member # 73) on April 10, 2007, 07:28 PM:
TRnCo,
The answer is no. Shot does not leave the barrel of a shotgun like water leaves the end of a hose. It is contained in a shot cup which keeps it together as it exits the end of the barrel. Actually the shot string, so to speak, is pretty bunched up as it travels.

Posted by Tim Behle (Member # 209) on April 11, 2007, 07:15 AM:
It wouldn't be oval, but you would miss the target.
When you add side to side movement, the projectile will continue with the same side to side movement as it travels.
That's why you need far less lead to hit a running coyote if you swing the barrel, as apposed to holding the barrel still and try to shoot a running coyote.

That`s what I always thought & was taught, it would be damn tough for anyone to do the math & consequently end up with an accurate shot under normal hunting conditions, I think I`ll continue following through on the runners & see how it goes, besides I don`t have room for all the charts, graphs, gps, calculator, range finder & laptop on a calling stand with me.

Exactly Tim,
When you follow a running coyote for a short distance with the crosshairs, you are ineffect matching the speed of the coyote with the speed of the end of the rifle barrel. As long as you continue to swing after pulling the trigger.
A loose term to describe this is called sustained lead. However, when using a shotgun with sustained lead, you do see daylight between the barrel and the target. The reason being you are shooting a target that is sometimes traveling 3 times faster than a coyote and the shot is traveling 3 times slower than a rifle bullet.

Well, obviously that wouldn't happen, for obvious reasons. But, the bullet WOULD be travelling that same 88 ft/sec initially, until acted upon by the other forces. Simple illustration, that I did not ten minutes ago. Rolling down the road at about 70 MPH, I spit my gum out the window. The gum did in fact stay even with my truck for just a fraction of a second, before the effects of gravity and atmospheric drag acted upon it. A bullet obviously moves much faster than my gum, and has less drag as well. So, of course the bullet won't still be even with the truck at 400 yards. But neither will it be even with the spot where it was fired. When dealing with closer, slower targets like running coyotes, I think the effect of barrel swing is fairly significant, and math showing otherwise be damned...
For me, this is all real simple, and basically goes back to what I think Tim first posted. I don't give anywhere near as much lead as the math in this thread suggest that I should. And I hit at least my fair share of running animals. So, my personal opinion, is that even if it were possible to instantaneously work out all this math at the time of the shot, it wouldn't be of any value to me anyway. And at the end of the day, the real answer is exceedingly simple - just go out and shoot at a lot of running animals and you'll get the hang of it (and likely realize how useless the math is...).

I not sure you guys are looking at this right. A four foot lead is a four foot lead. It doesn't matter if you hold steady in front(not moving the barrel) of a coyote and shoot when he's four feet from the crosshairs, or swing steady with a four foot lead or swing through from behind until you get your fout foot lead.
Posted by R.Shaw (Member # 73) on April 11, 2007, 09:16 AM:
Dennis,
I don't see 4 feet of daylight. My crosshairs are on fur when the trigger is pulled.
And here is something else. I have stood behind lots of guys while they were shooting a shotgun and I looked down the gun barrel as they shot. What they perceived to be a canoe length of lead, looked to me like 2 and a half feet. When a person is shooting at air, the distance between the barrel and target looks different to each individual. I don't shoot at air with a rifle.

That is correct Randy, but you have to figure in time of bullet flight. If aiming for the head and depending on speed of bullet, and distance you are shooting. the bullet is not going to hit where you are aiming. The bullet will strike anywhere from 12" to 24" or more.
You will have to calculate the time it takes the bullet to get to the 200 yard moveing target, then calculate the speed of target. and that wellbe the required lead. The coyotes head is not going to be where you shot at the time when bullet arrives.
I'll try to make it simpleer: Say the coyote is running from right to left and the coyote is south of you and there is a lone tree south of the coyote. You squeeze the trigger at the same time the coyote is in-line with this tree. The coyote willbe past the tree when the bullet strikes the tree. You have to allow time for the bullet to get from the muzzle to the coyote. Just say it takes 2 seconds for the bullet to reach 200 yards and say the speed of coyote is 5 ft. per second. Dureing the 2 seconds of bullet flight the coyote will have gone 10 feet past the point of bullet release..

I think the best advice is from Dave. Practice on jackrabbits. I have been told that some parts of the country do not have jackrabbits, which is unfortunate.
I'm sitting here wondering about an Abrams M1A1 tank, and how they hit another armored vehicle? Do they compute the math, or like DAA, they practice on Toyota pickups?
For me, I use the swing through, and when I miss, I think it is because I sometimes have a tendancy to stop my swing when the bullet is fired.
You know what? Shooting at a running coyote is an invitation to failure. I try to resist the urge as much as possible? (I have heard there are ways of getting them to stop)

That's too much math for me. But for the sake of argument, it does not take a bullet 2 seconds to reach 200 yards. The time of flight for a 53 gr. bullet, running 3800fps is .1830 seconds. The coyote ain't going far in that length of time.

DAA,
There is no question that there is no substitute for practice on running targets. I don't think anyone here is foolish enough not to realize that.
Most coyotes will be running at a different angle and different speeds but you still have to have a basic understanding of lead for each individual shooting style (swing and follow through). Will a chart be a substitute for experience when it comes to knowing those leads? Of course not!
There is no substitute for experience but you still need a starting point and thought process on lead. That's all this is no matter what the inevitable spin is.
If your shooting style happens to be that your swing follows the same speed as the coyote until you reach a point in front of that coyote, you squeeze the trigger and follow through, if that coyote is crossing the road in front of you at 25 mph and 200 yards away, your lead will have to be 6'. There is no arguing that. When that bullet leaves the barrel, it needs to be heading at a point 6' in front of the vitals of that coyote in order to hit it, period. You can change the swing and lead but you can't change the math.
Now either that is wrong and you can prove it's wrong or the math has value in understanding your lead in that situation WITH THAT SWING. I repeat, with that swing.
If you are not giving that much lead IN THAT SITUATION, than the coyote is closer, slower, at a different angle or you are swinging faster than the coyote. Which one is it because I highly doubt you will argue the math?
The bullet speed is constant, the angle in the above situation is 90 degrees (a coyote trying to cross the road in front of you which is a common situation), the distance is known, let's assume the coyote's speed is a flat 25 mph, the only variable in that situation is your swing.
I have a good friend that hunted coyotes in NE much the same way TA hunts them in MN. He told me that time and time again they would see a coyote run across the road in front of them heading to the other side of the section. Invariably, they would race to the corner, race to the next corner and by the time they got almost to the center of the section (1/2 mile - 1 mile - 1/2 mile), that coyote would cross the road just in front of them time after time. Now that is a very repeatable situation and knowing your lead in that situation could easily be applied repeatedly.
No matter whether you have a smooth swing with the speed of the coyote, whether you have a swing that is much faster than the coyote, whether you jerk, push or pull at the end of your swing as Randy Shaw does, or whether you stop in front and pull the trigger, each one of those situations STILL requires knowing the lead.
Experience will certainly teach you far more than you can ever learn from a chart. Nobody is arguing that but you can't argue the math in a known situation as the one described above which is the basis for the entire thought process behind leads.
I know where you and Tim are coming from but I also know the value in having a basic understanding of actual leads for KNOWN situations.
If this thread doesn't accomplish anything more than to give a novice a BASIC UNDERSTANDING of how much lead is required to shoot a hard running coyote traveling across the road in front of you at ABOUT 200 yards, then it has SOME value.
If this thread does nothing more than get everyone thinking about this, it has value.
To simply dismiss the math and say, "grab some shells and go practice" only leaves you to guess what the lead should be until you learn it.
Just the variance between shooting styles would render any chart basically worthless but a discussion of known situations gives anyone a basic understanding of lead.
This excercise was never about establishing a chart for each and every situation no matter how some of you want to spin it. Such a suggestion is insulting to me considering how many coyotes I have called and shot over the years. This is about a thought process on determining lead nothing more, nothing less.
Carry on!

Leonard: "You know what? Shooting at a running coyote is an invitation to failure. I try to resist the urge as much as possible? (I have heard there are ways of getting them to stop)"
I wholeheartedly agree but there is too many times where they simply won't stop (hard chargers) or you can't get the second one to stop after the shot.
I have tried every conceivable way I can think of to get that second coyote to stop and many times they do but there is simply enough times when they don't stop that you either learn to shoot running coyotes or you accept a lower level of success. Which brings us back to the "estrus chirp". LOL!

Randy Shaw: "But for the sake of argument, it does not take a bullet 2 seconds to reach 200 yards. The time of flight for a 53 gr. bullet, running 3800fps is .1830 seconds. The coyote ain't going far in that length of time."
First off, you need to divide 600 (200 yards) by 3800 to arrive at .158 seconds for 200 yards.
Then take your coyote speed of 36.6 fps (25 mph) and multiply it times .158 and see how far the coyote travels in that length of time.
Do you consider 5.8' far because that's how far he traveled if he was going 25 mph. If you jerk your gun before you pull the trigger and you are hitting the vitals, you are jerking the point of aim 5.8' in front of the vitals. You can't change the math.

So if I'm swinging my gun barrel left to right at a couple of miles an hour and the bullet spends about.000025 of a second in my barrel, I'm going to sling the bullet to the right?

I could'nt take it any longer so i made two calls today. I called hornady and Sierra and talked to the guys in the ballistic department. From what we have decussed almost everyone is correct.
Scott's formula is correct a 6' lead is required for a moveing target. But the formula is figured with a stationary barrel. The correct lead would be half that (3')Scott and others where also correct. Both guys from Hornady and Sierra agreed on this. The time of flight and target speed, is what you have to lead for.
i asked Sierra what they reconmended for a fur bullet for coyotes. They said the 55 gr. spt.
I then asked Hornady what they recondmended, A 50 gr V-max and a 52 gr. A-max. As a fur friendly bullets. The 52 gr. A-max does have a thicker jacket compared to the ballistic tips.
I asked both about shoulder or shoulder blade hits and both agree you are going to get some nasty wounds no matter what bullet you use, some more than others.
leonard: i'm going to over look what you said about the 17 cal..
Posted by Wiley E (Member # 108) on April 11, 2007, 10:53 AM:
Greenside,
It's an issue of where the barrel is actually pointing when the trigger is pulled as Rich Cronk correclty pointed out.
If your swing is faster than the coyote and you pull the trigger when that cross hair is at a certain point in front of the coyote, by the time the bullet leaves the barrel the barrel will actually be pointing ahead of where it was when you pulled the trigger because of the delay in the time it takes for your trigger finger to pull the trigger and the firing pin to fall. I don't think you are "slinging the bullet in the barrel". As you pointed out, a bullet traveling at 3800 fps is only in the barrel for .000526 of on second in a 24" barrel. That's not much time. LOL!
TA: "But the formula is figured with a stationary barrel."
What do they mean by that? A barrel that is traveling at the same speed as the coyote or a barrel that is not moving at all?

I'm confused,

The bullet speed is constant
and
quote:
First off, you need to divide 600 (200 yards) by 3800 to arrive at .158 seconds for 200 yards.
Bullets slow as they travel, a 3800fps bullet at the muzzle is what, 2900-3000fps at 200 yards?
I don't have a ballistics program handy so my 200 yard fps is a guess based off DAA's post in another thread, but regardless, the bullet is slowing right?
So wouldn't the lead need to be more since the bullet is slowing?
Or am I missing something?

Posted by scruffy (Member # 725) on April 11, 2007, 11:05 AM:
Also, when a coyote is running 25mph, your barrel is not swinging 25mph, it's pivoting on an axis (your shoulder). The farther away the coyote, 200 yards, 300 yards, etc, the slower you rifle pivots on the axis to keep up with the 25mph target.
But regardless, the rifle barrel is swinging so slow, maybe 1fps?, that it can't have any effect. Can it?
Again, still trying to understand the math and physics behind this.
Edit: one thing I've learned from being on here, it's better to miss infront than behind, hitting behind the coyote makes him run faster in the same direction he's travelling, however hitting infront of him sometimes turns him to running more straight away, offering a better higher percentage followup shot. So I error on the side of more lead. thanks!

Scruffy,
You are correct. I was talking in terms of IF we know the average velocity.
A bullet leaving the barrel at 3800 fps is probably traveling an average speed of 2850 (GUESSING BECAUSE I DON'T HAVE THE BULLET CHARTS) in 200 yards.
That means in 200 yards it takes that bullet .211 of a second to travel that far.
I didn't know the average velocity so I just used muzzle velocity.
Instead of the 5.8' lead for a 3800 fps muzzle velocity (figured as an average velocity above), 7.7' would be the correct lead if the average velocity was 2850.

and I'll guess I'll toss my two cents in on how fast they run away from me, even though it's the same thing I posted in another thread.
When I miss a coyote and he hears the "zing" of the bullet, a loud intimidating sound in his personal space, he runs for the next county. If he doesn't hear a "zing", I hit low becuase of a gross range mis estimation, a branch deflected the bullet, etc, the coyote isn't nearly as spooked by the far off boom from my rifle. He might stand and stare, walk or trott off, or even approach me but that probably only happens when the echos are just right and he thinks he's moving away from the boom.
Regardless, my answer is "it depends", on if the coyote heard a "zing" or not.
that's why on long shots if I'm not totally sure of the range or holdover I'll be conservative and not shoot over the coyote, hoping that if I do error that I'll get another crack at the coyote. Twice this winter I shot low on long range coyotes and both I was able to get back on and have a closer followup shot than the initial shot because of working the calls, relocating, and just a lot of good luck, LOL. When I've shot over a coyote it's almost always game over.
And, in line with my post a couple higher in this thread, I'm more aggressive in my lead, I'll lead as much as I think and if I'm not totally sure I'll lead a little more, so in the very least I'll miss infront, hopefully turning the coyote for a higher percentage shot at the coyote running more straight away and not so perpendicular.
So I try to kill the coyote on the first shot, but if I'm not sure on the shot I error on the side that will give me the best or better next shot.

Scott,
When I said jerk, I was referring to the trigger. The push or pull is something I do with my left hand to insure follow-thru. It is just a gentle continuation of the rifle in it's path.
When the rifle goes boom, the sight picture I see is the crosshairs on fur and most of the time this fur is on the coyote's head.
I am not trying to tell anyone how to hold on a running coyote. Just saying what works for me. I think anyone willing to try this technique would be surprised, especially on coyotes around 100 yards. And besides, what a better place to start. Shoot directly at the coyote and observe the results.
One other note.
I have seen guys swear that they shot behind a coyote and the shot was actually slightly in front. After they had recovered from the recoil and took a peek, the coyote had made one more jump. The cloud of dust had time to develop, but in that half second, now appeared behind the coyote making it look like the shot was behind.

Are you using duplex or mil-dot reticles? Might be some application there where you could at least ballpark and still hold on fur.

If you are not giving that much lead IN THAT SITUATION, than the coyote is closer, slower, at a different angle or you are swinging faster than the coyote. Which one is it because I highly doubt you will argue the math?
Well... Yes and no. I don't argue that the formulas aren't accurate for the variables they contain. I just don't think they are the correct formulas for the situation. As in, I don't think the formulas are accounting for all the significant variables - such as barrel swing.
I have no formula, and certainly no proof that barrel swing is as significant a factor as I believe it is. Hell, maybe I'm wrong, and it's not barrel swing, but something else entirely that makes a signficant difference not being accounted for by the formulas. My experience though, makes me believe that barrel swing is the significant variable not being accounted for. An example of why I believe so, and it is directly related to Leonard's ealier point about shooting off of sticks or a bipod etc. I know for a fact, that I tend to hit coyotes too far back, or shoot behind them when I'm shooting off of sticks. Same sight picture as when I'm shooting offhand from the standing position, swiveling at the hips, but my bullets strike further back than I'm expecting. I believe it is because of the difference in my barrel swing when shooting off the sticks vs. offhand. So, most of the time, when a running shot is called for, I ditch the sticks and jump to my feet to make the shot.

quote:
--------------------------------------------------------------------------------
I think the effect of barrel swing is fairly significant, and math showing otherwise be damned...
--------------------------------------------------------------------------------
Ditto. And I think if we get the math right, it will show the same thing.
That sums up my position pretty well, right there. But I also believe that there is so much variable, or variation involved in the swing itself, that it can't be modeled mathematically with any degree of consistent accuracy.
I'm not too clear on what TA17 was trying to communicate from Sierra and Hornady. But I think he said that they agree, barrel swing can account for reducing the lead by as much as half? I tend to think it can reduce lead by even more, based on the simple forumula numbers and my experience. But Hell, I don't know if that's even what he meant.
Again though, all I know, for sure, is that I don't give nearly as much lead as the formula says I should. And that works for me.
And I'm not suggesting that Wiley, or anyone else is seriously considering using charts or anything like that in the field. This is just kicking ideas around here. No sweat. I am suggesting though, that my opinion, is that these formulas being used in this thread actually do not give even a good starting point. My opinion is that they give a very misleading picture of how to actually shoot running animals. But, that's just my opinion. I have no facts or figures to back it up.

Yup. I've got a couple of these on video. Guy shoots in front of coyote, but swears he hit behind.
Oh, by the way, on the tanks, yes the computers do include the speed of the tank in the calculations. They have to. Else they would miss. By a lot.

I'd bet that the Sierra and Hornady boys were first talking about a stationary barrel. Anything else gets real complex real fast.
The usual math on this first figures lead from a stationary barrel. That's the basic fact of how far ahead the bullet has to be heading to account for movement of the target during the time of flight. As said, whatever the sight picture looks like and however the shooter achieves that lead, you have to have that correct lead or you miss. We can't fudge the physics.
Whoever mentioned pivot is on to the concept better than swing or sideways movement of barrel expresses it. In pivot, we are talking about angles, and it only takes a tiny difference in hand held physical angle to impart a big change in impact point at 200 yards.
Interesting stuff but I'm out of here for a few days. Real world work and travel sure gets in the way of hunting and fishing, and talking about them. Shoot straight, or rather in this context, shoot however it takes to hit what you're intending.
Posted by 6mm284 (Member # 1129) on April 11, 2007, 01:26 PM:
Abrams tanks do the math thru computer controlled fire. They hit moving targets while moving.
Lots of physics involved when you take swing into account. As the bullet gets farther down the barrel while swinging ,it is accelerating horizontally because the muzzle has to travel farther than the chamber . After leaving the muzzle, forward and horizontal velocity start to diminish,wind,temperature,atmospheric pressure blah,blah,blah..Even If I do all the math it would not help. .I just shoot until I hit them and let Albert Eistein worry about the rest.thanks
Posted by Wiley E (Member # 108) on April 11, 2007, 03:09 PM:
I have hunted pheasants for many years. One of the most difficult shots for me was always a high fast flying rooster coming right at me. I went to a steel shot shooting seminar once and the instructor told me that this was a very easy shot to make if you simply used the correct lead. He said to start directly below that bird and chase it until your barrel covered up the bird. As soon as the bird disappeared behind your barrel you pulled the trigger and followed through. Since that time I have crushed many pheasants with that lead.
DAA,
You could be right. Perhaps swing is the missing variable here but it's difficult to put into perspective because that coyote, if it's running 25mph, is still going to travel 7' from the time the bullet leaves the barrel to the time that bullet travels the 200 yards to the coyote. Somehow the swing and lead in combination has to be carrying that bullet that 7' but to the human eye, the lead might appear to be less than 7'.
What puzzles me is that this article descibed the swing and follow through but still held to the math. Since I know the math is accurate, perhaps the author was also mislead on the impact of the swing. Thanks for your objectivity and your point is taken.

swinging the barell changes the perception of lead. I'm surprised that no has brought up the can on the string. Take a can or any weight for that matter swing it around your head and let go of the string. the can does not curve forward. it goes out in a straight line. Your bullet does the same thing. Swinging your rifle allows for a more consitant lead rather than trying to hold a stationary barrel and trying to guess when the right time to pull the trigger is.

And speaking of pheasants, isn't it odd how some guys can shoot the lights out with a shotgun, but can't hit a moving target with a rifle to save thier ass, and then there are those that are visa-versa!
I've got a brother that kills running coyotes on a regular basis with his rifle, but when it comes to quail, pheasant or dove, you better be ready to shoot clean-up around him!
Posted by Leonard (Member # 2) on April 11, 2007, 04:56 PM:
Yes, I actually knew, instinctively that the tanks have programs that compute all that stuff, and probably involving a laser rangefinder, as well?
But, what I would like to address is the differences in the terms swing and pivot, as we might see when using the shooting sticks. The back part (chamber area) of the barrel is moving in the opposite direction from the muzzle.
If a guy is standing, or even sitting, he is swinging the barrel and the muzzle is moving faster than the chamber area, but they are both swinging, which is a little different than the example above with the tank barrel.
It seems to me that all of these things taken into account will affect the perceived lead versus pointing the rifle at a spot ahead of the animal and deciding that precisely six feet of lead is required; or any other number, at any other distance.
Good hunting. LB

Scott,
I can't help but to think that if the ability to hit a running coyote at 200 yards, is so troubling and important to you, that you need to debate it for 5 pages, maybe you need to put down the calculator and go out and learn how to call coyotes in to 50 yards and stop them broadside like the rest of us do?
There are a number of guys on this board who would give you some personal instruction if you offered them a fair price for their time. Maybe you should consider it?
Posted by smithers (Member # 646) on April 11, 2007, 06:51 PM:
TB, do you call them in to 50 yards or less and broadside because you can? Or is it because you are a lazy fatcat union worker that doesn't want to walk the extra 150 yards?
Posted by Az-Hunter (Member # 17) on April 11, 2007, 06:58 PM:
I know for a fact, that at 200 yards, a coyote running flat out, perpendicular to the shooter, will indeed soak up an easy six foot of lead. How the shooter does this, is where the squabbling comes in. I don't believe for a second that "barrel swing" has any effect on lead as we are calling it. To me,and Im a barrel swinger, all the swing or as better defined by Randy, sustained lead does, is aid in my aiming for where I want the bullet to end up after I press the trigger. I begin a running shot with tracking ON the coyote, maintaining a good paralell swing, then push the muzzle a bit quicker, in front of the moving coyote,and maintain that sustained push while comitting to the shot, till I "feel" it's right. Hopefully when all that happens, the sear breaks, I follow thru with the shot, or in other words, try to maintain the same speed in the push of the lead. It's a more fluid and easier method than a pull in front,and jerk the trigger kind of movement. To me that would be very difficult, becasue I would loose the cadence the coyote was running and probably not be on the same plane as the coyote, versus tracking on the coyote, then pulling ahead and maintain the same speed of the muzzle push.
So.......Leonards right, I have no damned formula, although Im not about to dismiss the fact that one does exist. As Scott mentioned, one can call it anything you like, but in the end, if your not at that magical 6 foot lead on that 200 yard coyote at a right angle shot, your never going to draw blood.
Im not to good at long shot runners, those at a right angle, thats a tough shot I think.
Give me a going away or quartering away shot,and sure, Im a bit more comfortable when they are "out there".
Inside of a 100 yards, at the angles most encountered with a fleeing coyote, I suppose a guy can nail them by staying on fur...at least the fur on the nose:) but man, when they get out past fort mudge, a coyote hauling ass is a tough target....IMHO, in my partiuclar situation,and in my particualr area.
Posted by JD (Member # 768) on April 11, 2007, 07:20 PM:
Good post Vic, I think someone mentioned the "percieved" lead, what it looks like through the scope, that`s definitely an issue, everyone sees things a little differently, also the come from behind & follow through method is similair to what Scott said about pheasant hunting. Regardless, a lead is a lead no matter if you use graphs & charts or you`re just plain good at it from experience but you & Scott have made a good point, you`d better have a decent idea of where to start on a running coyote before you go slinging bullets .
Just for the sake of argument though, swinging the barrel does in fact set that bullet in motion from one side to the other, I ran a few numbers on the speed of swing at 1 fps & it could possibly effect the lead by as much as 1 - 2 in. at 200 yds. but it certainly wouldn`t cut a 6ft lead in half.

I can't believe it, SOMEONE CALL 911 AGAIN, TIM BEHLE IS BEING FORCED TO READ 5 PAGES OF POSTS AGAINST HIS WILL AGAIN.
If you don't like thread and feel it's a waste of your time, don't read it Tim. Why is that always such a difficult concept for you to grasp?
As far as learning to call and handle coyotes, all I can say is, what a telling statement.
In your thicker cover, I'll bet you have no idea how many coyotes you call in that you never see let alone stop after the shot. What's a 200 yard shot in Southern Arizona? Down a dirt road between the mesquite and cactus?
If you think you can consistantly stop multiple coyotes IN THIS OPEN COUNTRY after the shot, you're in for a rude awakening pal. I haven't seen anyone that can consistantly do it yet. Must be one of those area specific things again huh?
Jump into a competition hunt around here and see if you don't change your tune Quigley Behle! LOL!
TB: "There are a number of guys on this board who would give you some personal instruction if you offered them a fair price for their time. Maybe you should consider it?"
Hahaha! Maybe I should!
I'll tell you what, when someone gets my attention with results on stopping coyotes that consistantly excels beyond my own methods, IN THIS TYPE OF COUNTRY, I might consider it. That hasn't happened yet. I doubt even Quinton Wagoner can get the remainders of multiples to stop any better than I can but I'm certainly willing to learn if someone has the answer to getting any and all coyotes to stop at 50 yards. That tip would be worth a fair price but I'm going to need more than cheap talk as proof first.
Either way, thanks for the tip!

Albert, there is an angular velocity imparted to the bullet, perpendiclar to the barrel and caused by the barrel swing. It is different than the can on a string you describe but is mathematically pretty much insignificant .To put it in perspective , if the muzzle swing is moving 1 fps and the bullet is moving 3500 fps then the effect of muzzle swing is going to be very small. As you say,the need for the swing and follow thru is to maintain the necessary lead.thanks

I think the correct metaphor for the anal tendancy to calculate lead on a running animal is "third eye blind", however nothing wrong with trying to get a ballpark figure. Let your brain do the calculating its much faster to have the feel for the shot (W/ practice of course) Thats why I love sport more than golf...
Hello all just dropping in anywhere here.

Albert, just noticed you're from Sask. I just got back from northern Saskatchewan, where howling wolves woke me a couple of nights ago. On the road again tomorrow.
One more comment re the can swinging on a string. That is not an exact duplicate of a bullet because the starting point for the can when released is at the outer or muzzle end of the string rather than starting from the holder's fingers at the center of the pivot radius.
The bullet starts near the center of the pivot radius and travels down a swinging, moving tube. The movement of the tube (barrel) may be miniscule during the time the bullet is in it, but the direction the tube is pointing when the bullet leaves the muzzle is axiomatically different than it was when the bullet started. It may not be enough to change the point of impact much, but the movement does have some effect.
And if there is any sideways movement of the can (or bullet), which there is, then that movement does not instantly stop but has to impart some angular motion, however small, to the projectile during the first portion of its trajectory.
As others have indicated, I suspect that far more crucial to the swing is the time lag of human processes and lock time rather than time the bullet is in the barrel.
