Just for grins I want back to the sporting goods area at WalMart yesterday. They didn't have any handgun ammo that I could see, no 22lr ammo and what ammo they did have looked to be high power rifle hunting ammo and only a very few boxes of it. Didn't check caliber but it's probably some of the less popular stuff.
On a side note, they had a decent stock of .177 cal. pellets but NOTHING in .22 cal.
Of course I've still got 750 left from my air rifle order. I'd like to order more too if I can.
