Some of you are using a heavier charge in your reloads than I am. For my 45acp reloads I am running 3.8 grains of bulleye over a Bayou 185 grain lead swc, this is in a tuned 1911 with a slide mounted red dot. I have also used the same bullet with 4.6 grains of HP-38, this load is just a bit hotter but still very mild. I am also crimping to .464-465 I think the biggest question is what size is the original posters bullet. I don't think the powder is the issue.
