I was just curious. I am loading H-1000, Nosler brass, GM215m, Nosler PP for 3093 fps. and 1/2" three shot groups @100 yds. One inch at 200 yds. Get fair accuracy with the 180 Spitzer 3/4" at 100. Wish I could get the Spitzer closer to the lands like the PP, but have magazine restrictions. Guess I will stay with the H-1000 load. I was hoping to find a powder that would equal the above with less powder volume. Has anybody tried the Magnum powder ?

Mine likes 70 gr's. of IMR 4350 when running the Nosler partition sp bullet...That load runs right at 3,000 fps in my 24" barreled ruger m77...
