Good day folks. Recently I picked up a S&W M&P in 10mm. I used a Lee .401 175 TC mold and cast up about 1k bullets. I have some unique on hand and plan on using that for my lighter loads (1,000-1,100 fps). What powder have you found works well for the full house loads? These bullets come in at 181 grains after powdercoating. I would like to achieve 1250 fps or so (4 inch barrel). Seems like longshot and AA #9 are the top 2 contenders for speed with the 180 class bullets. Would you go with one of those or something entirely different? If I remember right, I read that the AA#9 is an easier shooting/lighter recoiling powder in the 10mm than the longshot. But longshot takes fewer grains of powder, so more shots per lb of powder....
