Some .22 LR ammo is available
I have seen .22LR ammo for sale on sites like Midway early in the morning - say 6 AM Eastern. It only lasts a few minutes before it is sold out. I have recently seen Remington, Federal, and Winchester bulk packs - at normal prices.
I did not buy any as it was not the ammo that I normally shoot, and I do not believe in hoarding. The self centered guys that are hoarding, or trying to support their image as tacticool dudes are the problem. All of the ammo that I have seen lately has limits for the amount anyone is allowed to purchase, and it is still all gone in minutes.
