I just came across this and I have to admit that I no next to nothing about BP shooting apart from what I have seen on the net but one thing that is puzzling me is if every time that the gun is fired the drum rotates and should line up with the barrel so that the bullet/ball slides from the drum into the barrel this being the case why is it that the caps do not have the indent from the hammer/firing pin in the same place in each cap ??????????
