50cal t/c renegade

[Killitgrillit]

Howdy all, first time posting here just found the web site and love it.
The question I have is I just recently recieved a factory Kit 50cal barrel for the renegade in a trade, the outside looks good but the inside (bore) has 1:RUST twist, the inside of this thing is gone. rusted pitted bad

So now can this be reamed out to a .62cal (20ga) smoothbore barrel and if so who can do it and how much would that cost???? or is it now just a door stop or ??????? sell it on ebay for the thimbles underrib sights and so forth. Any Ideas
Thx Killit

Why not bore that barrel out yourself - just enough to take the rifling out and clean up the pits. Make a card punch from a piece of tubing for wads to fit, there is no pressing need to get a 20 gauge.

Buy a second rifled barrel from Green Mountain to round out the selection and provide a switch barrel set up.
