yep,thats why I posted ,because of getting the same power in .45 colt cases and saving 2.2 grains of powder by not using the loads in casull cases.I was kinda surprised because I figured I'd be in the 1200's with the colt case but the chrono tells the truth,...all cases(.45 colt) slid out without problems ,the primers were not flattened,didn't really show signs of too high a pressure,...but I think I have my load for my casull using this Lee 300 gr.cast bullet(.45 colt),...I shot off a rest standing and the .45 colt rounds were grouping 1 1/2 inces at 35 yards ,plenty of accuracy,....john
