This is silliness at its best.
I remember another panic (there really have been so many) where everybody was buying up all the small pistol primers. The rumor was circulating that the feds were going to outlaw the 9mm round, so, there went the primers.
But the large pistol primers were in abundance. I guess the panic shoppers didn't figure anybody could be killed w/a 45 ACP, etc.
Things will calm down.
Until then, I think I'll stop by Walmart and see if they've gotten anymore 22 ammo in.
