Ya, I think the 22 cazyness is still going strong mostly because so many people are still buying/hoarding it. I've also read that its pretty low on the list of calibers for manufactures to produce because the profit margin is so low.
I know I've walked away from shooting 22lr for now. Which sucks because it is so fun, but half the fun was also tied to it being so cheap to shoot, not anymore! I can't bring myself to shoot any when I think about how I used go shoot a 500 rnd box for fun over a few hours for around $20.
I've bought a little here and there over the last few months (like real little, like maybe 1-2k rnds), but it was all from the store at resonable prices and I was buying other calibers anyway.
I hope it comes back to the old normal, and sooner than later, but I've mostly put it out of my mind and just go shoot my centerfire cartridges.
