#MoldyMonday No. 19: the RCBS 40-180-FN

I've got a bunch of molds laying around that I've never cast, either because they're brand new or for some other reason just never used.
This episode is with the RCBS 40-180-FN that I'll be shooting in 40 S%W.
In this series, I plan to try to bring one of those molds out every week for a while until I get through most of them. Probably won't be EVERY week, but I'll try.
