I saw two 500-round cases of Federal 7.62x51 147-grain FMJ at the south BA Walmart yesterday, with a price tag of $375. I haven't seen that caliber on the shelf in a long time, and was wondering if anyone here has had any experience with this brand? I hemmed and hawed about buying a case, but since I know nothing about the caliber in this brand, opted to walk away. Should I go back and get it - if you guys reading this haven't already run down there to get them?
