I sold my .223 handi and the 17 Remington barrel, so I only had a RF frame that was the donor for the 17 rem barrel. Today I stopped by a pawn shop and bought a pair of Huntsman muzzel loaders with consitive serial numbers for a hundred bucks for the pair out the door. Don't know what I really have but they are cool, 58 cal and one looks like it was never fired and the other is really nice. They use the #10 cap and have a screw in breach plug. Nef's are just too cool to leave alone. Larry
