Shoulder Bump and Pressure Question

[Danale147]

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?

Bumping the shoulder does not affect pressure.

Bumping the shoulder does not affect pressure.

If anything, bumping the shoulder back more increases pressure in my experience.

I suggest you back off your charge because your case in stretching under excessive pressure. Sticky bolt lift and sticky extraction are to be avoided. There are multiple "nodes" throughout the velocity range. Find a lower velocity accuracy node.
