I have a savage/shillen barrel in 222 mag ai i have pushed 40 gr nosler bt,s from 3400 fps. (24gr, h-322) to 3800 fps.( 28gr h-322)brass shows no pressure signs and brass lasts quite a few loadings.i,m sure these are high end loads. i have had great luck with that powder, as well as varget. i have pushed 35gr. v-max,s to 3950, they pile into the same hole at 100 yds. it,s a very explosive bullet going that fast.
