[QUOTE="jraulsten, post: 2431673, member: 96652"] I've owned several Bartleins and never experienced this with any of them. I'm seeing both sticky bolt lift and ejector marks. I immediately stop when this happens and pull the bullets on remaining loads. This was all virgin brass that I resized (without touching the shoulders) and trimmed to length (1.95") before loading and firing. Another way I know pressure was excessive is the fact that I separated that brass and tested in the gun by removing the firing pin and ejector. The bolt would not fall and they had to be bumped back .002 after one firing! That is either crazy high pressure or ADG brass isn't what everyone claims it to be, All brass that showed no signs of pressure after the first firing had head space growth of .005 from that of virgin brass, and did not require setback.
