My job sent me to an area today that I don't often frequent. Naturally I asked the locals to point me towards a gun shop. I was browsing the .223 and the owner goes "If you're just looking for something to burn up, I got this." And he pulled out a case of American Eagle in black boxes like this ... I know AE is made by Federal. But, I've never seen a black box. I came home and did a quick nets search and all I could come up with (as far as a review) was a single post from AR15.com: "This is believed to be the exact same as xm193 in the old school brown boxes." The guy's price was $7.99/box. I'll be back in the area tomorrow. Is it good ammo? The price beats Wal-Marts $8.52 for Remington/UMC. Is it worth pulling out the credit card and stocking up? Sorry for the ammo question here. I just figured I'd get better/faster responses than in the "ammo section."
