    Primer test is all done I am sticking with the BR2 the groups dont lie.

    I loaded up 24 rounds to do a seating depth test I shot four six round groups at 200 yards from the bench over a backpack.

    The conditions where cold 27 degrees, wind was calm 1 mph at the shooter bright and sunny.

    I shot fast no waiting between shots
    The load
    185g VLD
    Nosler brass
    CCI BR2 primer
    81.0g H1000

    I started .010 off the lands and the group was low I only hit the paper 3 times I dialed 5/10 of a mil up for the next groups

    The group things got better at .050 off the lands

    Then they opend a bit at .090 off the lands

    And then even more at .130 off the lands

    The setup

    Im going to re shoot .050 off the lands for 3 groups as I think I pulled 2 shots. I felt as if I was to fast on the trigger. After that I think I will go down twards .090 off the lands as it got tight at .050 and did not go crazy by the time I got to .090 so there is a sweet spot there and .050 might even be it.
