Re: 270 WBY MAg Load Question. help

3077fps with a 150grn pill in a 270 roy is just getting started, run the wby where it likes which 99% of the time is balls to the wall. My go to was 74grns of RL22 under a 140 accubond for 3433fps avg but that was from a 28" barrel. I could hit 3320 with 150s and H4831, Imr7828, or RL22, and a handfull of my cases had 10+ reloads on them, always good to hit a norma/wby case with a mild load first to work harden the case head, then start lighting a real fire in em! Good luck.

Love it... got the discussion started.

I'm running 73.5 gr of 7828 with a 140 AB. It's hot, but shoots really well in my bee.

3250-3275fps, more if you use a CCI250 or 9 1/2M because the primer won't have as much start pressure.
