According to both my LGS's. They claimed they were getting their normal shipments of 22 cal ammo. but due to hoarding, that was the shortage cause. Everyone in my area has 22 cal ammo in stock now. For some reason, ( due to increased production from what I'm told.) about January of this year, it made a huge comeback. And the shops say they are ordering and selling more than ever before. I don't think te profit margin was all that big on 22 rimfire either. So that may have also contributed. The price on popular caliber pistol ammo has almost doubled since 2008. 45apc, 44, 357, 38, 380 prices were just flat out gouging ridiculous for the past several years. But recently has started to drop again.
