    I'm new to reloading but I think I'm understanding the importance of consistency in the complete process. I'm not looking to bench rest shoot, just want to take the ammo errors out of the game.

    • Win Brass 2.008, (1.6235 shoulder)
    • Necked only, fire formed already
    • CCI #200
    • Shoulder bump .0015
    • SMK 175
    • COAL 2.825
    • To Ogive 2.250
    • Varget (41.5-42.0) under development


    Went out to the property yesterday and shot 3 groups of 3 (41.0, 41.5 and 42.0 each group) at 201 yards and the results showed the 41 gr seemed to be the furthest (lowest) from the group.
    Vertical drop from rounds 2 and 3 were .28, .32 and .27 MOA respectively per group.
    This is the vertical distance I'm addressing with charge weight per research.

    First group of 3:

    The additional groups showed the 1st round (41.0) another .4 - .5 MOA lower.

    So last night I pulled the remaining 41.0's and added a little powder to put it in the middle of the 2nd and 3rd rounds. I now have 41.5, 41.7 and 42.0 for Saturday at the BRC to finalize which charge weight to stick with. Pretty happy with the consistency of the rounds compared to Southwest Ammunition's Match junk.
