I don't see a way to load the cylinder on the conversions. You must have to remove the cylinder, and load it in a separate press. Funny that they call them muzzle loaders, I doubt they push the charges down the barrel to load the cylinder.

The Ruger Old Army, is about the best most modern black powder revolver ever made, IMHO.

The hot setup, would be a full size cap and ball revolver, with an avenging angel cut down revolver, for concealed carry. With multiple cylinders that could be used in both revolvers. Use the full size as the loading press for the cut down one.

I doubt in places that only allow you to own black powder revolvers would let you carry one for protection.
