[QUOTE="stanley52, post: 877938, member: 62465"] The 60.1 was getting 2850 with a 1:9 26" Bartlein. Yeah I was confused initially because there was no sticky bolt, no web expansion, no excess brass flow, no primer flow, minimal primer flattening, only thing was some decent cratering. When I was working up I didn't get punctured primers till 62.5gr of powder and even with that this was the only pressure signs. The 60.1 did not blow primers at first, then it started blowing them a bunch for some reason, then I had it bushed and turned, and after that it just had a few punctures so I dropped a couple grains of powder and it still punctures them way too often 1/5 maybe, though the hole is very small compared to before. I do wonder if it's a bad lot of primers being that there were 4 misfires in 40. The primer strikes were very deep and the entire primer was crushed in a bit (as expected). There was no reason they shouldn't have discharged. So I called CCI and they said to use their BR2's because they're tougher... First time I had ever heard that and cannot find anything on the Internet to verify that, but CCI said so... So I guess I'll listen and try? Just would like to not spend a ton buying 5 different types of primers. [/QUOTE]
