[QUOTE="bob4, post: 1227126, member: 57171"] Working up a load of Barnes TSX 180G BT in 300 WM 64gn -66.5 gn of rl-22. 2 rounds gave me a hard bolt lift. Real hard. This is very conservative for this load but the Hornady brass has been fired 7 or 8 times at this point. I brought the 2 pieces of brass home and measured everything I could think of and it all seemed correct. No other signs of pressure so I continued shooting that work up with no other problems at all. That's 2 out of 24 rounds gave me a hard lift. The only thing I noticed is a ring of scrape marks around the base. None of the other brass shows this. Couldn't feel anything with a paper clip so I split one open and nothing. Pics to follow.
