I am getting similar results as you guys. My 7.82 Patriot with 70gr H4350 and 150 TTSX shot about .65" at 100 at 3295 fps avg. It shot .5" with RL17 at 3335 fps avg. I have not really worked it up in larger bullets but the H4350 worked well with 180 AB's at about 3050 fps.

Anybody tried Magpro with the WSM's?
