I was doing load development with varget and 120 eldm, and the brass is brand new starline. Anyways this weekend just a rough trial to check how it would group. I was not checking speeds or sd/es. When I got to 26.6 I noticed a swipe on the 3 pieces and at 26.9 the swipe was there again on all 3 but one had a decent stamp, no burrs was created on the case head. My setup is a 18 Lilja with A5 buffer system H0 buffer non adjustable gas block. Would an adjustable gas block help with the swipes ? 26.9 is not near the max load. Thanks guys
