It's been around a year since I've seen a box of 22LR at our local Wally World, of course I don't have their truck schedules, 100rd. box is largest, one per customer, we will know things have definitely went south when they break the boxes of 50 and 100 up and restrict customers to one bullet per visit per day.
The latest 223/5.56 debacle caused a rush, seems to be coming back, the cheaper stuff like tul ammo is still non existent.
