I've shot a pound of Pyro select and half pound of RS to find what it likes best. Loves the T\C .50(.452 black) 240gr. XTP with 80gr. pyro. Next would be a tie, Hornady 300gr. (.430 green) XTP over 90gr. pyro, and a 295gr. powerbelt over 90gr pyro. These will make clovers at 100 yards. I bought some t7 to play around with last week . I can't find anything that will group less than 3"- 4" at 100yd. I shot 180,240, 300 XTPs, SSTs and 295 powerbelts all with 90-80-70-60gr. of t7. With nothing to brag about. So I went back to the pyro, and everything was tight again? What am I doing wrong? I know I should load 15-20 % less t7 than loose pyro. Thanks wood-tick
