Just got my .340 Wby Mag back from the gunsmith. Had a new Lilja Match barrel installed with a bunch of other work. Factory loads chamber with no effort, but my reloads won't chamber, can't close the bolt. Looking at the brass I try to chamber, I see where it is getting stuck in the chamber on the shoulder. It is not a problem in the head area in front of the belt. Brass fired in the new gun resized in my RCBS dies work fine also. Just wondering if there is a brand of reloading dies that might be able to resize the brass from the "old gun" so I can use them. I have close to 500 cases I need to work on.
