Thought I would share: 155 grain Precision Moly Bullet, 5.5 grains of Red Dot, COL =1.13 velocity on a 90 degree day == 1137FPS, PF==176(mass x velocity/1000) shot from a 5 inch 1911 Bar Sto Barrel. no signs of excess pressure. I backed them off to 5.2 grains. Velocity on a 90 degree day == 1102 FPS, PF==170 (mass x velocity/1000) Why Red Dot: it fills the case, and it was in stock. As it turns out, it shoots nicely as well.
