There is only one LGS that has .22 mini-mag ammo for sale. He's asking $10 a box. No one is buying it.
AT the shooting range where I'm an RSO I heard that one LGS had bulk boxes of .22 but he wouldn't sell the ammo by the bulk box. He was only selling the ammo in lots of 50 rounds at $7 each.
I reload for every caliber that I shoot with the exception of .22 and I'm not going to pay high prices for it.
