I have been informed that first generation 45 Colt Colt SAAs require pressures that are generally used for 45 Colt revolvers in "Cowboy Action" shooting. Obviously, loading current brass with black powder would be below or meet such pressure levels. What I find regarding exterior ballistics of factory "Cowboy Action" 45 Colt ammunition is that there is a large variation in listed muzzle velocities among different factory cartridges having identical bullet weights when all cartridges are loaded with smokeless powder (via Midway Arms' web site).
Please identify smokeless powders that can be efficiently loaded to yield "Cowboy Action" pressures with 250- and 225-grain cast lead bullets. If possible, include TiteGroup as one of these powders. Hodgdon's web site' 45 Colt handloading data are not as clear on this subject as I prefer. Pressure levels are listed, but I do not know what "Cowboy Action" pressures are. Without this information, Hodgdon's information is not yet useful.
