check walmart....there was lots of .22 ammo in 2 walmarts I went to...not much else..unless you use 28 gauge ammo, and a few other odd size ammo.
I checked the local Walmart; no .22 cal at all, no handgun ammunition at all, almost no long gun ammo. A couple of boxes of .410, and somewhat suprisingly, several boxes of 30-06, but almost nothing else.
