beast44k,
Put a Leupold on it and advertise for top dollar on the scope/gun combo. Cheaper scopes won't pull a sale like a good scope will. Selling a used muzzleloader is alot different than selling a used smokeless rifle. Everyone knows muzzleloaders are dirty and the suspicion that the gun is corroded is very high even with good care. Also coupled with the fact that your model is waning in popularity to the inlines and that lots of muzzleloaders are very cheap sitting brand new on the shelf pushes the resale values way down. Why not keep it as a back up or as a spare buddy gun?
