I find it hard to believe that anything that the government would buy would affect the supply of 22 ammunition. Yet, that is the ammunition that seems to be completely gone. I see various pistol ammunition available; I see shotgun ammunition available; I see some high-power ammo available. So, what is the explanation for 22 ammo?
I have also heard that 22 rifles are the most common guns in public hands. Surely the public doesn't think they are going to protect much with a 22.
