Guys, help me solve this delemma I am having. I have a Remington 700 chambred in 257 Wea. I have had problems with brass in this gun from the start. Factory brass chambers fine, but my reloads are very tight and can't close the bolt on some. The brass fits before I run it through my fl resizing die, then it gets too tight. I bought a Wilson case gauge to set my headspace back minimally thinking this was my problem. The reloads that I have will go all the way down in the case gauge to the headstamp but these are very tight in my chamber. The fired brass (not resized) will not go in the case gauge pass the belt but chambers smoothly in the rifle. Also, the brass on reloaded rounds sticks out past the end of the gauge like it might be too long. The only thing I can come up with is that factory ammo and fired brass (not resized) fit in the gun because they are headspacing off the belt and not the shoulder. When I fl resize them, it resizes the case enough where it is headspacing off the shoudler and for some reason becomes very tight to chamber. I have been stressing over this gun for months, I have sent it back to Remington for inspection and they sent it back saying everything met specs. Please Help

Re: Weatherby Dilema
I think you're partially there with the belt/shoulder idea. I'd guess that when you FL your brass you're not pushing the shoulder back and the case is growing.
You need to set a die, either your full length or a neck/shoulder bump die, to push the shoulder back about .003; that or just neck size and verify that they chamber before you take them out to shoot. If they fit why FL them?
Get a Hornady Case Comparator for your dial calipers and check your case lengths at the shoulder.

Agreed, that would be the most likely cause but it somewhat conflicts with the posters observations. Assuming the case guage test is worth anything.

The comment that the reloaded headspace is set off shoulder and not belt should be natural. I'm not a belted mag reloader but ill try to help.
You checked datum to case head with the guage.
Things to compare: I don't think the guage will a account for where the case body meets the shoulder below the datum, the rifle's chamber will. That case guage also does not guage body diameter so body distortion above the belt might also be issue to compare cases with. The latter should be from firing, not from resizing. However, you stated that fired cases chamber.

Re: Weatherby Dilema
All cases will chamber but I have to force chamber some. The fl resized brass is just tighter than the once fired. I think my problem might be in my extractor/ejector. I read this on another forum and sounded like we are having the same problem. My damn ejector is extremely stiff and I get brass shaving on my bolt face every time. http://www.predatormastersforums.com/forums/ubbthreads.php?ubb=showflat&Number=1785610

Re: Weatherby Dilema
Here is another idea. Belted magnums have an issue the bulging above the belt. No FL resizing die can correct this problem. However Innovative Technologies has a collet die that is specifically made to correct this problem.
Now given what you described I don't think this is your problem but it is a little food for thought.

Re: Weatherby Dilema
I don't know if it will work but you could try to sharpie a case all black then chamber it and see where it rubbed off. Sort of like bluing a valve seat after you lap it. (the ex-Navy nuke coming out in me)
Edit: Rather than blacking a case you could probably run 2 lines up the length of the case and see where the line breaks after you chamber it.

I thought about this and even called Larry. However, with the brass going all the way to the belt lip, I don't see how this will help. I am tired of this gun, I am going to take it to the smith and get him to look and see if the chamber needs polishing or maybe a couple coils cut off the ejector spring. Right now that's the only thing I can see causing this. All the brass does have marks that start where the neck meets the shoulder and runs halfway down the case body.
