I lucked onto a Navy Arms Bisley (1873 Colt Bisley Clone) in .44-40 today. Only two spots of minor wear and it was mine for $275, a price I could certainly live with. I have a Navy Arms Schofield, in .45 Colt, but because of the design, I'm a bit hesitant to go over the "cowboy" SASS shooting type loads. I probably would have bought it in .45 Colt too, but I've since taken an interest in .44-40 and voila, now I have one. I plan to use a 200 grain JSP (first the .426 diameter, with the crimping groove where it belongs) and IMR 4227 for propellant. I'm going to try for 900-950 fps out of the 4 3/4" barrell. I figure for out to 35 yards or so, that will be plenty good deer medicine for the Midwest where I go on an annual deer hunt. In addition, it should be a good winter load for Montana, where most of the bears are usually hibernating, and wolves, lions and coyotes may be the only real concern, (predator calling). In the past my winter handgun has been a Model 27-2 S&W with 158 grain JSP @ about 1000-1100 fps. This should be a little lighter and have more "fun factor" for me, as I'm a single action fan.
If anyone has any information about handgun hunting with the .44-40, either jacketed or lead fodder, I'd be interested in reading your experiences and the stats on your load. Just curious what I've got to look forward too.
