Thanks for all the information. The bore is bright & shiny with strong rifling. There is a bit of holster wear on the sides of the barrel extending app. 3/8"-1/2" back from the muzzle. One aspect I'm curious about is on the cylinder stop slots. There is a extremely slight burr on the fully squared (stopping/following) side of the slot. It is barely perceptible with a fingernail. This is the first time I've run across this. Any theories as to what caused this burr/mushrooming? Since this cylinder was not heat treated, is there a safe threshold for handloads to be fired in this revolver? I'm not a subscriber to hot rodding handloads. Thanks again!
