Magpro powder

I shot RL22 in my 280 AI until the season changed and so did my point of impact! I use H4831sc now and love it. I shoot 140 grain accubonds and CCI BR primers. Believe it or not the primer made a big difference in my groups. 59 grains of H4831sc with CCI BR primers and 140 gr. Accubonds gives me 3 shot groups at .338. I can get velocities up to around 3100 fps which I use for hunting but 59.0 grains gives me about 2900 fps, light recoil and sweet accuracy.
