This was my wife's grandfather's "yard gun" that she inherited. I never met him since he died years before we ever met (which is a shame, he sounds like a fun guy) so I don't know much about the gun (or pistols in general, I'm mostlya rifle guy). All it says on the barrel is ".22 Caliber". I found an old owners manual online and it lists this gun as shooting short, long, or long rifle.
Does that sound reasonable? Is shooting 22 shorts out of a revolver with a long rifle chamber safe? I've shot 22 shorts in a rifle, but the barrel is attached to the chamber in a rifle, so I'm not sure about a revolver.
