I hit a large number of Walmarts in my area this week - seems to be a spike in 22LR ammo? Got quite a few boxes of M*22 and (I think) 25 boxes of Federal 550, half of which are already gone (to shooters and their kids).
Many of the stores I hit usually get only 1 case of the 550 - I know 3 stores got 3 cases, and one got 2 or more (didn't see 'em, just going on what the clerk told me).
One of the stores that I've never been able to get 22 ammo in (grumpy white guy always working, denies seeing any 22 in ages, and beats you over the head when you ask) I actually walked out of with ammo in hand today!
I've pretty much given up on this store, as in over 10 trips when ammo is supposed to have been delivered, I never got any.
Since I was in the neighborhood, I gave it a shot (I figured the grumpy old white guy might stick his neck out a little too far one of these days) - a different clerk was working, and when I asked him if he had rolled out today's 22 shipment, he reached under the counter (a no no) and pulled up 3 boxes of 550.
I guess maybe that's where the grumpy old white guy always hid it when he always denied having received any?
