I have a Ruger M-77 .270Win & .22Mag and have used the Mag as a smallgame/predator rifle in the Thickets of Blackwater Swamp, but I need to reach-out on some clear-cuts and will be using the .270. The lightest round I can find is the Rem.Express 100gr. psp rounds in local stores.
I'd also like a Bullet Drop Chart for any round I'm using.
Thanks,
Dave

I think the jury is still out on using light bullets in large capacity deer type cartridges? For instance, some 270s can't handle 90-110 grain bullets, accuracy is less than acceptable and they cause a lot of damage. On the other hand, a standard 130 grain bullet may also cause damage, but they seem to shoot a little better, especially at longer ranges.
Good hunting. LB

I think your right. I dont think there is a good answer.
I havent shot alot of coyotes with deer calibers, but have enough to know this. My 300 Win Mag with 150gr Rem Core Lokts does much, much less hide damage than my 25-06AI with 75gr VMax.
So, if the question is what would be the best to use in a 270 for coyote FUR, I would have to assume the harder, controlled expansion deer bullets would be better than any of the light "varimint" bullets.
Now, if you just wanna kill to kill and make a mess, then thats another story.
Thats my experience anwyway.

Andy pretty much hit it from my experiences too.
Big heavy jacketed deer bullets will usually make two holes ( As long as you don't hit a major bone ) But those light weight varmint bullets tend to make a mess, unless shot a low velocity.

I am not saying I disagree with you guys because I don't have enough time in the field with my .270 to be a good judge.But I shot my .270 for a couple years when I first started calling and I had pretty good luck with the Sierra 90 grain hollowpoints running about 3100fps,if I remember right.I think I was using IMR 4350 powder but can't remember the amount of powder I used.As far as I remember it Seemed like I had acceptable pelt damage.FWIW Chad

I'm not disagreeing with you, either, Chad. In fact, as I recall that is exactly what I used for about two years when I first started, 90 grain Sierras and IMR4350. I think my opinion is that it's not worth the trouble to switch, if you already have a decent big game load? But, my recolection is that damage was considerable with those HPs, but at the time, I didn't care? I ultimately decided that I wasn't getting "Nevada" accuracy, and sold the gun in favor of a 6MM.
Good hunting. LB

Last year I switched my .270 over to the remington express 100's when I finally gave up on my .223 (mini14) as my primary predator rifle. I'd shot a few coyotes before that with 130 (winny cpx2) to 150 grain (winny cpx3) psp's and like has been said above, little hole in, little hole out, as long as you don't hit a big bone. The 100's did the same thing but with less recoil. On broadsides shots I always got an exit but on frontal shots, even one facing me at approx 50 yards, the shot didn't exit. Just a small entry hole in his chest.
Accuracy in my weatherby was around 1"-1.25" at 100 yards with the scope on 9x off a harris br bipod and a 'V' block (cut from scrap 2x4 and contact points covered in felt) under the butt stock. This rifle does much much better with 130's (the winny cpx2's, hornady SST's, etc) around .75" or under. This rifle does 150's consistantly around 1".
So the 100's were the worst as far as accuracy, it really likes the 130's. But the 100's are accurate enough for my purpose (under 200) and have alot less recoil IMHO so I shot them more at the range practicing. Not to mention they are pretty cheap compared to alot of .270 loads (for us that don't handload).
For my rifle if I was going to build it into a long range rig I'd probably shoot the hornady 130 grain SST's or maybe try one of the Remington thicker skinned plastic tips in the 130 grain swift loads.
If you look at the specifics and ballistics for the 100 PSP and the 130 plastic tip bullets (on remington's web site) you'll find the 130's have a MUCH better BC and at long distances are the same or actually flatter. You'll have to look at the remington sight for ballistics, but I was thinking the Remington 130 grain Swift Scirocco was flatter than the Remmy 100 psp's. The 130's would have more recoil, but for my rifle they would be more accurate and with the extra weight and much better BC they are just as flat at long ranges.
Hope this helps.
later,
scruffy

Thanks PSPs, so I'll just zero for the lighter loads.
Where can I find a Trajectory Chart for the Rem.100gr.PSP as there isn't one on their website....

Leonard,That's kind of how I felt about the .270.Not accurate enough for my taste.If I remember though The 90 HP's at 3100 fps had about the same point of impact as my 130 grain big game bullets at 3000 fps(at 100 yards).I could be wrong though I can't remember that far back anymore.But I got smart and bought me a Remington 700 in .22-250.Boy what a difference that one made.I've Shot it for almost 20 years,until this last season, I've been messing around with this new .204 Ruger.FWIW Chad

Swampcat, I think you meant 100 grain remington express PSP's? (model #r270w1)
Here's remington's website for the different .270 loads they sell, including the 100's.
http://www.remington.com/products/ammunition/ballistics/results/default.aspx?type=centerfire&cal=17
Has all the good stuff, velocity, energy, BC, short range trajectory (zero'd at 150) and long range trajectory (zero'd at 200, except 100's are zero'd at 250).
And it looks like trajectory wise the 130 accutips and scirocco are both flatter than the 100's past 300 yards when zero'd at the same range, with the accutips being a freckle (.5" at 500 yards) flatter than the scirocco's.
Just fyi incase the 100's don't group MOC (minute of coyote) and you want a flat bullet with alot of knockdown and controlled expansion that won't tear up the pelt to bad.
good luck!!! ![[Smile]](smile.gif)

Swampcat,
Give Point Blank a try.
It's free, accurate and you can customize it to the exact load that you shoot.

Thanks for the help! Trajectory Chart was a great help from Remington especially for the 250yd zero.
I'm going to my huntclub range tomorrow and run a few 130s & 100s downrange for group. If the 100s group well, I'll use them; if not, I'll just use for shot-practice....
