No ammo at Wal-Mart, either!
I wonder who polished off the checkering on the extractor rod.
I wouldn't have bought a gun in that condition. But I hope it works for you. You probably know the power is about on par with .40 S&W. Reloading the bottle neck cases may prove difficult, with a high rate of ruined cases.
You presumably have, Sixguns, so let Elmer be your guide, keeping in mind that some powders may have changed and he loaded hot much of the time.
That gun was made between 1897 and 1905, so I'd load carefully. The frame was improved in 1905.
