Could I use .45 ACP dies for reloading .45 Long Colt?
I know .45 acp bullets are .451 and .45 long colt are .452, but it doesn't seem like that would matter much for expanding and seating, and it seems like the die could be long enough for those two jobs as well.
What I really mean is, are they safely interchangeable? I'm not going to try it if they are not. But I'd love to save myself fifty bucks.
