1st, was this brass shot in your gun? If not, it has to be Full length sized, and cam'd over. If it was shot in your gun, then you have a chamber that is oval cut. Or out of round.
It was brass you picked up and shot from others guns, and you have chambering issues then die is out of tolerances. What brand die? FL or neck sizer?
You should be able to only neck size and be able to chamber.
How does new factory ammo chamber? Have you taken your calibers and compared the measurements?

After careful inspection, I find that the bottom of the brass, closest to the primer is a little larger and obviously did not get resized which is allowing the bullet to go into the gun, but not allowing the bolt to close properly. I readjusted the die and started resizing last night and it is so much harder than normal. Got a couple stuck, but a little added pressure freed them up. The one that is in there now refuses to come out. If anyone is curious, yes I lubed the entire case. I did take the deprimer out to save my current new primers that are already in the case.
Any ideas on this brass and what might be the problem? I am guessing that the bottom expanded when shot although I can not prove it. The initial resize/deprime was NOT hard at all and covered about 80% of the brass. It is that last 15-20% that is giving me trouble.
Any help is appreciated.
