I have both a carbine & long rifle in 43 SPANISH REFORMATO. I shoot 43 SPANISH in them and they fire form, almost a straight case. I load them with 27 GRS of IMR-4198, with a 45 CAL. LONG COLT bullet, thumbed pressed into the case on top of drier lint to keep the powder against the primer. so, in stead of using up my 43 cases, what case can I use to form them out of? the 43 SPANISH cases I make out of 348 WIN. after a lot of fileing on the drill press, till they chamber, then fire form them.
