I use 49.9 gr. of H4831sc with Hornady's 129 gr. SST. I get 2840 fps and 3/4" groups out of my Rem. 700 "Mountain Rifle" with a 22" barrel. This load is very compressed, so work up to it slowly. Taken 3 hogs(135, 175, 215 lbs) and 2 Axis bucks(125, 150 field dressed) for 75 to 285 yds, and have not recovered a single bullet, complete penetration.
