With mine, 67.5 grains of RL-19 and 165 ABs gave me right at 3,100 fps and produced 3-shot groups that hovered around 1 inch at 100 yds. For elk, I ended up going with 200 ABs and 69.0 grains of IMR 7828sc which gave me 1/2-inch 3-shot groups and 3,0000 fps. YMMV.
Damn, that's a smoking hot load for those 200 AB's....You could pile drive the hell out of an elk with that load
