Just installed a new barrel and just came home from the range. I've hones down on an accurate charge, but am starting to see the very faintest of ejector marks and maybe just a little bit of sticky bolt lift. I'm bumping the shoulders back 1.5 thousandths now on my handloads, would going another .5 or 1 thousandth bring the pressure down just a bit, or should j just back off the charge?
