I just bought my first reloading setup and I also bought about 9000 .452 bullets at an estate sale, both 225g f.p. and 230g r.n. and I was wondering if I can use them in a 45 long colt case? I bought them for my 45acp but I am looking at a 45lc blackhawk, and that would be an inexpensive way to enjoy a big bore single action. I think it should work by the info in the reloading book, but I just wanted to make sure.
