Normally, when I go to Cabelas they have .308 ammo in at least three bullet weights from at least three manufacturers. Today they had no .308 ammo. Zero. Nada. Zilch. And the gun counter there was packed. In addition to the 30 guys looking at guns, there were another 15 in line to do paperwork for purchases.
I guess with the Obama administration planning to limit firearms ownership - especially of 'assault weapons' - people are rushing to load up on military chamberings.
Maybe Dick's will have some .308 ammo.
