I had a similar situation with a Skimin and Wood waterfowl/ live pigeon gun that a previous owner decided that he should shoot steel shot through. Not only did the guy (no woman that I know of would be this dumb) succeed in scratching the bore (scratches since largely polished out) but he also decided that it would be a great thing to take a hand hone to the chokes and use it to ream them off-center. The reaming left precious little "meat" for choke tube installation but Briley got the job done, though with a certain amount of trepidation.
I guess I was lucky, in a way. I had a pretty clear shot at "customizing" this gun because "Boy Genius" eliminated any concerns that there would have been about "collector's value" before I bought the poor thing. For being a big, heavy beast by British standards (30-inch barrels and 8 pounds, 2 ounces)I now have a very usable gun that is now much more versatile than it was when it was new.
