Is .22LR even available on the shelf yet? Last I heard that was still in short supply, even though larger calibers are becoming available.
Not in my area. I will sometimes come across some but it's typically out of stock the day it comes into the store. They also jack the price up by double in some stores when they get them in. I still have about 1,500 rounds of .22LR that I got lucky enough to snag one day. I was able to buy a 525 round box, and a friend bought one for me as well, it was their last two boxes. Then when I found some 9mm, they had 5 50 round boxes left of .22LR, they only let you buy 4, so the guy in front of me got 4 I got one.
That was about 3 months ago, I haven't seen more than a stray box here and there lately. Dicks, and Dunhams are my local stores and I'm in a populated area so it's hard to find ammo still.
