I saw a Mossberg 500 at the Rockbridge flea market last weekend for $250. It looked pretty good.
Ohio Valley has a few good used shotguns as well. I haven't been in Down's or Jerry's to see what they have for some time.
I used to hunt with a H&R rifled 20 gauge. It shot very accurately with Federal 3" sabot slugs. Lately I use a 870 with a smooth slug barrel. It works.
I am sure there are places around Hocking county where a guy could get a 100+ yard shot but not where I hunt.
