Tell me about it. I just went out to the local gun shop at lunchtime. No.22LR to be had. On the other hand, they did have a nice new supply of AR-15 P-MAG 30's at $24 each, which is way down from the "panic" days a few months back, so I picked up a couple to add to the SHTF box. They also had a good supply of extended mags for .22... just no ammo to full them with.
PMAGs and windowed PMAGS were plentiful at the Dulles Gun Show this weekend.
I bought 3 windowed for $42 total.
