A couple months ago, I was searching for 200 pieces of new brass since I use Lapua, but Lapua was not available, so I contacted Peterson and asked if they could send me some samples to try before buying and they were kind enough to send me 7 pieces of 6 BR brass as samples to try. I loaded 27.5 and 27.8 grains of Varget tipped with 105 VLD, and .010" off the lands. Last month at the range, I tested them, and got hard bolt lift on all 7 pieces with head swipes on each piece. The powder weight is .5 grain under max and the velocity was only 2650 ish roughly off the top of my head and I was surprised on the results because I get 30 grains of Varget with Lapua brass, and velocity is 2825 fps and no signs of pressure or hard bolt lifts or swipes. I was wondering why I'm getting the head swipes. There are no flattening of primers, or pressure signs on the brass except the swipes on the head / hard bolt lift.
