I've visited the nearest 3 walmarts here and they were all very low on ammo... no handgun ammo at all except for .357SIG (one Wal-Mart had a few boxes of .44mag). No .22 ammo (that one suprised me), and pretty low on rifle ammo. They were out of .270, .30-30, and I bought the last two boxes of .30-06 at one of them. Surprisingly, they seemed to all have at least some 7.62x39 and .223 (WWB).
Maybe this means that the "assault-weapons" side of the buying craze is slowing down (?). I don't know. Wal-Mart dudes told me that they get shipments in every week and it take about 2 days for the shelves to get to the point where I saw them. Prices had not gone up, as far as i could tell, from pre-election.
Oh yeah, the one Wal-Mart that still sells rifles were out out Mini-14's, Marlin 60's, and maybe a few others.
