OK First time with my black power revolver. I have a Pietta reproduction 1860 Army. Took it to the range and loaded one cylinder. Thing goes fizz bang and not mark on the target. Examine gun, ball is stuck bout an inch in the barrel from the cylinder. OK.I take it home examine the gun and punch out the ball. This is what I find. I dunno what to make of it so I clean the gun again, this time leaving the cyclinders dry, zero oil. Couple of days later go back to the range. Load one cylinder, fizz bang, nothing. Ball never made out out of the cylinder. So I am thinking, just load another and try. Fizz bang I hit the target, I am not impressed, so I load another cyclyneer. Fizz bang, ball stuck in the cylinder. Now I am thinking maybe not enough powder, so I increased the amount from 15 FFG to 20. Fired, fizz bang, it hit the target. Well, I took the gun apart and in the two failed cylinders was a significant amount of powder left. Only thing I can think of is am I using the correct caps? #10? Am I measuring the powder correctly? What's with the delay with the time hammer hits cap and explosion? The fizz bang thing? This gun is really cool, and I would like to have fun with it.
