I have been working on some loads with AA 2230 (a fine ball powder) behind Hornady 55 grain soft points, using CCI small rifle primers. 2.200 coal.
Shooting ten round groups I found 23.5 grains to be the most accurate charge weight in one of my ARs. However I consistently get random flyers. Flyers may end up any where in relation to the main group. Generally 4 rounds in about 3/4 moa and 1 blowing things out to 1.5 - 2 moa. It is not consistently happening on a certain round fired, ie the first round, but it is pretty consistently happening with about 20 % of the rounds fired.
Isnt me or my technique, I can call my shots quite well and can shoot 3/4 moa with factory match ammo.
My loading technique is solid and my charge weights are very uniform. I uniform my primer pockets ( since I use a progressive press) and can feel the primers seating uniformly.
Those bullets have a pretty good rep for decent accuracy.
Is it likely that I may need a magnum primer? I can't recall ever seeing published load data for 223 / aa2230 using anything but standard primers.
