I've been trying to develop some lead, (.452/.453), 200 and 230 grain round nose loads to work in both my RIA 1911 GI and my Ruger Blackhawk Convertible. I've pretty much determined that my Blackhawk chamber throats are about .001/.002 smaller than my RIA. If I load for my Ruger and the case gage I've got, my OAL is down around 1.22. The grease ring lands on the lead bullets have to be seated even with, or below, the case mouth or else they jam the Ruger. At that OAL they perk right along in the Ruger but are too short to reliably feed in the RIA. If I load them out to 1.25 +/-, they run fine in the RIA but jam the Ruger.
Jacketed bullets, (.451), aren't near as sensitive and I can load them to 1.250 + and they work fine in both guns.
I can handle this by simply labeling my loads and marching happily on and/or using jacketed bullets but, it's been driving me nuts. I probably ruined 150 rounds by over-crimping to get them to fit both guns but, then, I didn't want to shoot them so I pulled the bullets.
Anyone need some tapered .453-.444 lead bullets.
