At least at the range I frequent most of the .223/5.56 range brass is once fired and it's quite easy to recognize. Seems a lot of people go to Wal-Mart or Academy and buy the cheapest stuff they can find and just bang away with it. Shooters are supposed to sweep it up and put in a barrel for resale, but quite a few don't. It doesn't worry me a bit to pick it up and use. YMMV
JOG, another reasonably priced and accurate bullet to keep in mind is Hornady's 55 gr soft-point with cannelure, $12.59/100 at Graf's just now.
