But a converted 1860 sure is one fine looking and sweet handling gun. The cartridge transfers the pressure directly to the recoil plate and frames tend to stretch much more quickly, that's especially of concern with the open top Colts. These are with a very light load of Red Dot giving about 850-900fps and 25 yard groups under 2'.Ĭartridge cylinders put much greater stress on the frame than does a cap & ball cylinder where the initial pressure is contained entirely within the cylinder. I stand them in the loading block and dribble a bit of Lee's liquid alox over the ball.
457' ball seated just deep enough for a roll crimp to not bite into the ball. 454' bore that will require you to ream the cylinder throats to. This always results in poor accuracy and fouled bores. The 200 grain bullets do much better but best is a. Some people buy a conversion cylinder for a black powder revolver with. First the rifling twist of 32' was meant for round balls and accuracy of any 250 grain bullets is piss poor. I stick to very light loads for two reasons. The gated conversion is as quick to reload as any single action cartridge revolver and with smokeless powder there is no messy clean-up. I have the Kirst five shot gated conversion on my 1860 Pietta.
