Guys - got the Renegade today. The barrel is in good shape. It looks as though someone had 'freshened up' the snail to remove some surface rust but it is in good condition and the nipple threads are good. I checked them. The bore looks brand new. The only other thing I noticed is that there is some minor blueing wear on the side flats from the stock. But some cold blueing could fix that in a couple of minutes.
So a T/C 54 cal percussion barrel for $60 - who wants it.
