I picked up a case of PMC .223 (55g BT) tonight at MCSports in Bloomington for $350 ($6.99/box of 20). This is brass cased ammo (reloadable). They had at least four cases left.
I did however have to point out to the guy that was waiting on me that the Fiocchi 50 round packs he was trying to sell me as a good deal at $20.00 are .40 a round and the PMC in the 20 round packs at $6.99 was just under .35 a round!
