I came across a set of rcbs .45 shotshell dies on cast boolits forum a few months ago. Knowing that rcbs stopped making them, i snatched them up. Made a few, but they are a little long for the mag if my sig P220. I will have to buy a 1911 in .45 just to play with these.
I first used commercial .308 brass, then used .45 mag brass as it is the same length as trimmed cut down .308 brass.
.410 wads, and a .375 gas check. The seller also included a c&h star crimper that reduces shot capacity, but helps feed in my p220. "
The July 1979 issue of handler magazine is still available to buy, that's what MJ from the ammo channel used.
