[QUOTE="Pudgy, post: 2631172, member: 124264"] It’s a factory rifle. It’s a Proof Elevation MTR. Virgin brass work flawlessly. Then I amp anneal, fl size, Henderson trim, wet tumble, mandrel 2625. And load. 80% of the loads I have to literally tap or beat the bolt down. When I take the round out I don’t see any marks on brass or bullet. When I go to put the same round in I have to tap/beat it back in. They fire well with no increased pressure signs and velocity the same as those that feed fine. Shot a 60 round f-class with it today. Sd for the 60 rounds was 9.1 at the target. After firing the round feeds and extracts easily. Headspace is fine, lower case at .200 is good, trim length is good, the only thing I can think is the chamber neck is too tight. I can’t fit a round into a spent case. Going to try turning the necks from .0135 down to .012 and see if that solves the issue. Any other suggestions? [/QUOTE]
