Saw some at the gun show in Tulsa last weekend, at a wildly inflated price, and not in quantities previously available. Difficult to impossible to reliably find on line. Heck, even .22LR and .22 Mag are in short supply, especially bulk pack. Wannamaker's (a BIG gun show) is coming up in April, so we'll have to see what things look like then.
I was at a gun show in Rochester NY a few weeks ago. There was a guy selling 200 round battle packs of 7.62x51 for $200. That’s a buck a round. Ouch. I should have invested in ammo back when you could get a case of 1000 from the Sportsman’s Guide for about $130. This is why I will never be rich. Only my hindsight is 20/20. My financial foresight is closer to Ray Charles.
