Handguns, I've only loaded .44 Mag. It's been a long time. I can't recall what I used, but it was a carbide set.
Reloading son's H & K 45 acp. On Amazon they list an RCBS carbide set for 45 ACP but then they ask for size, and list "colt" and "one size." I suspect that's a wrong listing - suspect it's just the 45 colt and not 45 ACP.
What die set do you use?
