I bought a used .270 WSM which came with brass, dies and some handloaded ammo. Well I shot all the loaded ammo and it's time to reload. Most of the rounds that came with the gun were hard to chamber (it was a difficult to close the bolt). Well I neck sized the brass and ran them through a body die only to find that that did nothing to help. Well I've turned the body die down a few times but it still hasn't helped. I measured the cases and I know they aren't too long, so that's not the problem. What can I do get them to work properly? How far can I keep turning down the die before it's pointless? Is the brass toast? Any suggestions would be appreciated. Thanks
