Update: I went out this morning and finished up the break in with some of my own handloads. Once that was done shot a 5 shot group for accuracy. I had 5 different loads to test this morning, but it was just too cold and windy. However, I was pretty pleased with my first group. It was fired prone (on the ground) off a Harris bipod. The load I tried was 52 gr AA2700 In a Lapua case with WPA primer. Bullet was a Sierra MK 190 gr seated .002 off the lands. Like I said, cold and windy, the range was 200 yards. The group measured out at 1.5" not too shabby I think for my first attempt and considering the conditions (if I say so myself). At that point I decided to quit for the day (on a good note).
