Does anyone here have any experience with Remington's "cheap" .223? Dick's Sporting Goods has the stuff on sale for $7.50/20 rounds, which is the cheapest I've seen brass .223 going for a while. I picked up four boxes last week, and three boxes this week. (I don't really buy in bulk, just pick up 2-4 boxes every time I go somewhere I can buy it.) I'm mostly wondering whether the stuff is excessively dirty to the point that it's not worth shooting, or if anyone's had any other issues. Haven't had a chance to make it to the range recently to find out. It's not intended for match shooting or anything like that--just more for the pile, in case.
