Vic,
I loaded a lot of 9.3x72R,with 9.3x74R dies, before finding 9.3x72R.I just removed the expander plug,deprimed by hand, and made an expander/beller for the correct diameter, for use with a hammer.Seated bullets with 9.3x74R seater,didn't reach the crimping shoulder, but I don't crimp these cast bullets anyway.This amounts to a "neck sizing die set".
