45 colt and cast my bullets. Lee hand press, dies, and bullet mold. It's an old H.E. 2nd mdl .455 butchered to .45 colt so i don't burn lot's of powder per load. At this point i think it costs under a quarter a round. I can reload about 200 to 300 rounds before it starts to feel like work and i rarely shoot that much a week. I want to handgun hunt so i will spend more on a .44 and dies in the future but for now it's really cheap and enjoyable.
