[QUOTE="Kroberts, post: 1316097, member: 71507"] Pretty much what I'm trying to find is that I'm getting the most performance I can while maintaining the primer pockets as well as I can. I think I was measuring a bit too far forward due to how wide of a measuring surface the micrometer has. At the moment that is a 180gr SMk at ~2900 fps from a 32" barrel using 55gr of H4831. And getting 10 loading from the blue box lapua brass before the pockets start to get loose and on the 12 loading there is no resistance while seating the primers, but they stay put. I'm using a forster full length sizing die so that it just bumps the shoulder for easy feeding. I have no idea if the actual amount of bump. But if I back out the die about 1/32 of a turn then the cases get very difficult to chamber after a couple firings. Due to a fairly large chamber neck I anneal the cases every 2nd firing.
