I had a 22-250 rebarreled and am having problems w/ 'some' of my hand loaded ammo.
All factory ammo loads ok -BUT i can shoot a factory 45gr win. round NOT have any problem extracting the case -then trim and neck-size the case and the bolt will not close on some of the rounds..??
I say 'some' b/c others will go right in with no force on the bolt??-confused bigtime
I can take a once fired win. factory round full length resize it - -then have to force the bolt closed on the round.On the ones that won't chamber there is a bright ring low on the shoulder.
I've been given the advice to get a small body die but refuse to -they're not for bolt guns.
I do not want to send the gun back to the smith--can anybody give me their thoughts?--Thanks Mike

Youre gunsmith may have cut the chamber to tight, or there is something wrong with the full-length sizeing die. I would try a different die first and if that don't cure the problem then go to the smith. What action are you useing? Check to see if the seated primers are in far enough also, should be flush... good shooting... T.A.

It's a rem. 700 .
The dies are lee deluxe set -full ,neck ,and seater die.They build perfect ammo for a xr-100 22-250.
I have several boxes of win.45gr 40 per box ammo bought it dirt cheap and figured i'd smack pd's w/it then have some good brass.
I shot them during barrel break in and when i neck-sized my brass some of the rounds wouldn't chamber.Trimmed -chamfered -and full length resized some won't chamber w/o a lot of force.

Sounds like you might have been cut a small neck chamber designed for match rifles.
Call your 'Smith and check with him, you may just need to turn the necks.
Are they hard to extract after firing?

I wouldn't worry about small base dies, they work okay in bolt guns, although that is not the intended application.
The bright ring MIGHT be from attempting to close the bolt on a cartridge that the shoulder wasn't bumped back enough? But, if the factory round was fired in your chamber, the bolt should close with just neck sizing, but it could close hard?
Unless the chamber was not set back properly, allowing the whole cartridge to grow in length.
So, what it sounds like to me is:
#1 you are not resizing properly, (doubtful)
or #2your chamber has excessive headspace and the bright ring you see is incipient case head separation.
I think your gunsmith needs to get involved. You should not have to have a mess on your hands, just to handload your once fired cases. Just because you can fire factory cartridges, does not mean the chamber is correct.
When he fixes his screwup, I'd also lose the Lee dies. Get a Redding full length die, and then partial full length resize, if you want?
Good hunting. LB

There are lots of things that could be causing your problem. But a few are much more likely than others. And they are all easy to check.
First step is to actually get some measurements to work with. Start with headspace. Measure headspace on the factory ammo, fired cases and resized cases. If the issue is chamber headspace and/or die adjustment, you'll see it clearly from these measurements. You can use a piece of pistol brass on the shoulder to get relative headspace measurements for this purpose. I'm assuming you already have a good dial caliper (the most used piece of equipment on any loading bench). Headspace problem could be chamber, die, combination, or even simply die adjustment. Good tight custom chambers often run up against a production die on the long end of tolerance, resulting in a die that can't size ammo quite short enough for what is actually just a very good tight chamber. I've run into this several times. Easiest fix is to grind some material from either the top of the shell holder or the bottom of the die. Before doing either, make sure you've got a good hard cam-over on the die with no slop. Just screwing the die into the press until it hits the raised shell holder won't give you that - you'll need another 1/8 to 1/4 turn on the die after hard contact with the shell holder to make up for spring in the press (which they all have, just some more than others). Small base die is NOT the answer for this, by the way. The SB die does more sizing on the body, but not for headspace. An SB die MIGHT be the cure for shoulder diameter issue.
If headspace isn't the culprit, measure neck diameters next. Same deal - measure factory, fired and reloaded (with bullet seated). If that's the issue, neck turning or cutting a new chamber neck are the fixes.
If chamber neck checks out, then I'd measure shoulder diameter. If that turns out to be where you are getting hung up, it could be a chamber out of spec, a die out of spec, or more likely just an unhappy stacking of tolerances where both chamber and die are within spec but on opposite ends of acceptable. It really isn't that uncommon. Just another die will probably cure it. A small base die would be a possible answer too - but I'd avoid the SB die you can.
There are a few other less common issues that it could be. Like poor lubrication inside of the neck and/or rough expander causing headspace to get screwed up when pulling the ball back through the neck. But those kinds of things don't seem too likely here.

"On the ones that won't chamber there is a bright ring low on the shoulder."
This makes me think there may be a problem with the chamber. I would check it with a borescope.

Thanks for the help everybody.
I'll break out the caliper and do some measuring as instructed.
One thing i read is -when you buy brass and start loading your ammo keep all your brass on the same amount of shots.I think that will help b/c i'm not sure how many firings some of the brass has on it.
Mickey Coleman rebarrlled the gun for me -he's supposedly known for his chambering.He assured me he checked and rechecked the head space.
Said to send it back to him if i felt there was a problem.He's a great guy to deal w/ but i just don't want to send it back unless i have absolutely have to.
So i'll do some measuring and try another die to see what it does to my brass.
