I am looking at a Iver Johnson Second Model small frame 5 shot 32 at my local pawn shop. It has all of the nickel worn off but the gun locks up tight and the rifling is very good. I would like one of these for a shooter. I would reload for it but would rather not have to use black powder. I don't know much about old wheel guns and the black powder days. I never thought I would be loading for something like that. Could I use something like pyrodex for it? Or should I even consider shooting such a gun. They want $120 for it. If I can get if for $100 and can shoot it (with pyrodex or even black powder) I might buy it. Any suggestions or info would be appreciated.
