ISO 12 gauge single shot

[lil bubba]

I know this is a long shot but I have a busted left shoulder and I can really use a 12 gauge 28 to 30 inch full choke single shot for deer. In the B.C. it is shotgun only and I can use my pump or auto but an old fashion single shot would be much easier and lighter for me to tote. Not looking for a bargain but willing to pay decent price for a gun you may have laying around. The ones they sell now ain't fit to shoot sparrows......
