Gander has .223 in stock (Federal) in the 100 round bulk pack and 20 round black boxes (AE223) - none was priced but there was a pallet of ammo being unloaded and it looked like plenty more hanging out... I expect it was more than the $9.99 per box Cabelas is charging for the same stuff and had in stock up in Rogers about 30 minutes earlier (10 box per customer limit now in effect). Dick's had boxes of TulAmmo steel cased for $7.99 a box over in Coon Rapids... 6 boxes per customer. Sounds like Fleet had some earlier as well... Plenty out there if you look, sounded like the manufacturers were getting things caught up on the ammo side and I figure it will ease a bit after the first of the year when everyone is sitting on their wallets after their payroll withholding goes up a couple hundred bucks a month.
Looks like $0.33 per round for steel and $0.50 for brass cased is about normal for the time being at retail.
Good luck finding mags or AR rifle components still, nothing out there... though there was a single DPMS 16" AR10 pattern rifle sitting in a rack at Cabelas about an hour ago for $1099.
