Great score!!!
I used to own one many years ago and should have never sold it.
They are probably the best made (modern) percussion revolver of all time. 30grs Of Pyro P and a Wonderwad/wax cookie under the ball gave very respectable accuracy but they get dirty fast.
This is one of the few times i would suggest trying APP or JSG powder.
BTW Clements mods them to 50cals if you feel the need for more knock down but at a heavy price tag.
