I have a Sauer cape gun in 16 bore x .43 Mauser from the chamber cast. Both barrels have been milled in England to make them usless. They can be sleeved and the ribs are still good. Other problems: stock is loose but I can see no cracks on the outside, gun is slightly off face, the toplever has been replaced with a badly fitting POS. The photos show what's good. $200 + shipping.
