I'm using the following .308 hand load: Lapua brass, neck turned to .014", OAL: 2.007" BR-2 primers 46.5 grains Varget Berger 155.5gr Fullbore I have never had pressure signs from this load in roughly 300 rounds and loaded it as high as 46.8 grains. My Bartlein barrel has 3,850 rounds through it. Still shoots 3/8" groups when I'm paying attention. I just cleaned with Wipe-Out overnight, ran 2 patches through it and brought it to the range to shoot 30 rounds. After shooting the 1st 5 round group, I noticed extractor marks on 3 cases. I'm assuming that it was the 1st 3 cases. One is a pretty hard mark and the marks diminish from there. The rest of the 27 cases that I shot have no marks or any other pressure signs that I can see. Did I simply not get all of the cleaning solution out? Aside from being one of the better groups or the session, the cold, clean bore group is unremarkable. 3/8" and same POI as the rest of the groups.
