But then, I re-timed it when I did the action job, and all rounds fired since factory test firing have been black powder, which doesn't leave those permanent black rings on the chamber mouths.
The one thing I hate about the Rugers, their abysmal timing.
I think that the 3 screw Rugers shouldn't have the lines. They time the same as a Colt. Aren't the Vaqueros set up to use a half cock to load/unload?
