The Wal-Mart in Clarksville is where I've had my best luck with .22 and 9mm. I picked up a couple boxes of 100 round 9mm bulk packs for 26 bucks each last week. And they seem to have 50 round boxes of .22 fairly often.
I checked at Gander Mountain, Lima Road in the Fort, today. Shelf was full of 9mm WWB for $19.99/50rnd box. They also had about ten boxes of Fiochi for $17.99. It was still too high for me, but it is good to see a good supply on the shelves. Lots of .223, 5.56, .308, .30-06; also .4oSW, .45ACP; plenty of 12ga 00buckshot, etc.
