Gun: 10mm S&W Bullet: 180gr HP XTP Powder: Tightgroup 5.9gr 12 shots average FPS: 1035fps I just loaded and chronoed the cartridges above. I want to reload with a 180gr lead bullet. But I don't have a good load for a lead bullet in a 10mm. Dropping the load from 5.9gr to 5.5 should get the fps down below 1000fps.I also have HP38 and WSF powder. Any thoughts or concerns?
