Can anyone suggest what on earth caused this scoring at the rear of this revolver cylinder? I purchased he gun used in the late 80's and this ring was on it when I purchased it. It detracts from the gun when viewed up close but when the revolver is viewed at arms length, the charcoal blueing makes it appear as a gold ring around the cylinder. This was my first Cimarron revolver and I really like this revolver. Bullseye ejector, BP frame, and beautiful case hardening.
I know this is NOT bolt drag since you can see the bolt race forward of this scoring. The frame does not impinge on the cylinder and there is at least a 10 thou gap there. No screw face is there. I just can't imagine what may have caused this scoring which is around the entire circumference of the cylinder. Suggestions?
With rifle in hand, I confidently go forth into the darkness.
