Just starting to get into reloading for semiautos, though I have reloaded for rifles and revolvers for some time. This specific question is for the 9mm Luger. I have a mold that is designed for cowboy action and is a 100 gr truncated cone with a large lube grove (see below). Currently, I just have a 358 size die. I know this is a bit large for 9mm, but will this cause an issue? Just looking to make some plinking loads that will work the action, not hotrod. I have Unique on had, so that would be convenient. Thanks for any insight you can provide.
