    I picked up a new redhawk rifle here are the specks .

    Remington 700 308 20" barrel 1 in 12 twist .
    Timney trigger set to 2lbs
    HS Presision stock .

    Load
    178 Amaxs
    Winchester brass neck sized .002 neck tension
    Federal match primer
    RL 15 42.8 grains
    Ran them thru my chrono 2515 I had deviations from 9 to 11 FPS
    Here are my 100 yard groups this is a 4 shoot group at 100 yards I only loaded 4 for some reason don't ask why ?

    Went out to 400 yards and groups where still good under MOA .

    Doped to 600 yards could not hit the target ? I did notice that the last 15 loads I loaded and shot had .007 runout on them could this be my problem ? This baffles me ?




    I know that 180 grainer are about max for a 1 in 12 .

    All charges were hand weight , and all cases were trimmed to 2.005

    My runout was from seating the bullets with a standard redding seating stem , then I switched to the VLD seating stem and my runout changed to .003 to .001 run out .
    This is just bugging the S*** out of me ?

    I am 40 off the lands at 2.185 base to ogive .

    My first though was a stability issue but I don't really know, Kind of adding this comment so I don't loose track of your thread when an more knowledgeable shooter gives you the insight.

    When you went from 100 to 400 Did your POI shift left or right any?

    You dialing or holding over? How much wind you shooting in? You sure your scope is level when your firing?

    No shift in POI at 400 yards

    Dialing scope

    Wind was at 10 at my 6:00 .

    Also scope has a level .

    I am thinking bullets are not stable after 400 yards

    I will load and go back to the range this weekend and shoot at 400 and 500 and see what it does this time out .
