I've been lurking awhile so thought I'd go ahead and post some of my history along with a question. My grandfather and uncles started my career in shooting at the tender age of 6 with a Model 39 Marlin but I never saw a cast lead bullet until my uncle pulled out his .38-55 drilling to shoot a buck that was walking across the pasture one winter afternoon. I began casting when I was a teenager, having been handed an original 1860 Army Colt when I was about 14 after being shown how to load and shoot it. I spent many hours burning my fingers while trying to use that little iron mold which threw a picket bullet and a ball. That old Colt would easily stay on a Clorox bottle at 50 yds and do it all day long - which started my love affair with short guns. I bought a bunch of Saeco equipment in my early 20's and shot lead out of anything I could lay hands on - some experiments were successful and some not. Marriage and kids came along then twenty more years went by before I did much more with lead pills (I'm still loading stuff I cast in the 1980's).
Enough about me - here is the issue and a question. I have an Old Model Ruger .45 LC with 7-1/2" bbl which has always been capable of one ragged hole at 25 yds with 7.5gr of 231 and the old H&G #68 in linotype. That was plenty good for many years and my sons used to call it "Quail Medicine" as it was capable of popping heads off bobwhites if I could hold it close enough. My 2nd son is now a working ranch manager and wanted a .45 revolver to pack on horseback so I located a Colt clone by Uberti with adjustable sights and 5-1/2" bbl. I loaded a few hundred rounds for him with an Alberts 225 gr swaged bullet and 7.0 gr of 231. It's accurate but shoots high at the lowest rear sight setting so I thought a lighter bullet would work and was considering the #68 as a possibility.
However, here is the dilemma; I also have a Rossi 92 that I shoot heavy loads of Blue Dot with 250 JHP bullets - and my son wants to get a carbine to complement his pistol but I would really like to try and develop one load that will work across the board for both of us and is interchangeable with rifle and pistol. I figure the Uberti is the weak link so I need to work up a max load with it in mind. I don't believe the #68 will work in all of these applications and am thinking about a 230 gr calvary-style bullet. I also question whether I should find a gas check design or just stick to a PB since I won't be pushing anything to magnum speeds. BTW, we are shooting feral hogs, deer and varmints up to 100 yds so a flatter trajectory would be a plus. Any thoughts or suggestions are appreciated.
