[QUOTE="Frog4aday, post: 1667867, member: 9308"] From Shooting Illustrated article ([URL]https://www.shootingillustrated.com/articles/2012/2/16/problems-with-primers/[/URL]): "Dave Emary, Hornady's chief ballistics scientist, says [U]excessive headspace[/U] can cause [B]primers to back out[/B] or even pop out completely. There can be other culprits, like a rifle chamber cut very tightly, a throat cut too short or a barrel with a tight bore. On rare occasions, the cartridge brass might not have been properly annealed." Assuming your loads really are below max, then either the brass is crap, or it's time to get the rifle checked out by a GOOD gunsmith. (Used to be able to just say "gunsmith" but now you never know who is going to hang out a shingle and claim the title.) [/QUOTE]
