Every time there's an ammo scare, 9mm/5.56/.308/7.62x39 fly off the shelves, but there are stacks of .243, 7mm-08, and 6.5 creedmoor are left sitting there.
I’ve only seen 7mm-08 at cabelas, one federal load was all they had. The had no 243, and neither has any other shops except I found 5 boxes at academy last week for $35 a box! For basic federal ammo. And 6.5 creedmoor is as common as 308 on the shelves right now. But I haven’t seen 243 since this time last year.
