250yds+: 162 Hornady Amax, Norma brass, Fed 215GM primers, 75.5gr AR2225 (Compressed), 0.020" jump (single feed), MV: 3050fps. Shoots 1/2 MOA groups and far better when I am doing my job right. I tried to seat these at mag fit but the accuracy was inconsistent.
Note: groups are only validated out to 400yds as that is as far as I have been able to shoot paper.
