i have a cz model 3 in 300wsm. i started with 100 new winchester brass, i also have an assortment of range brass. the winchester has been fired 2 to 3 times. brass fired in the cz and reloaded fit very tight, a little too tight for a hunting gun. it is hard to close the bolt. while my other bolt rifles with neck sized ammo are a snug fit, this is beyond snug. it has nothing to do with the case length nor the bullet seating depth.
i have tried to full length size them, but that did not help. i screwed the die in farther, when the brass is in the sizing die the shell holder touches the die. effort to size is more than most of my other calibers.
i had thought that i would just put the size die in the lathe and turn a few thousandths off of it. but, of late i am thinking that the problem might not be the die, but the brass itself. perhaps the brass is springing back? a fired case chambers easier than a sized one, but still fits snug.
i swear there was a thread about this issue before, but i cannot find it.
the dies are hornady, they are far from my favorite brand of dies.
