Under no circumstances should you fire that shotgun with modern ammunition. It was made for black powder. I have an old damascus 12ga. double that belonged to my grandfather, but I reload with black powder and the shotgun has been well taken care of.
If you want to clean yours up a bit, remove the metal and soak it in penetrating oil, wipe off with rags, soak again etc. until most of the heavy rust is gone. Once that has been done, rinse off with solvent or mineral spirits and re oil with gun oil. You will probably have to re oil every couple of days or so until the gun oil has completely soaked into the metal.
No such thing as a stupid question. What is stupid is not asking it.
