Here in NC I also belong to another forum and its called the Carolina Shooters forum. I looked on there last night in the ammo for sale section and I found at least 6 different folks wanting to sell 22lr ammo, most in bulk packs that had laying around. The prices were a lil steep but not too bad. Example, $40 per 500 pack, sometimes less. None were offering shipping, had to drive to their meeting place.
The point is, explore your local area shooter forums, local gun ranges or clubs that have a website. Local Craigslist or sale newspaper ads.
Good luck and hope this helps.
