Before we moved back east, I sold off some surplus 5.56 I had, since it was "easy to replace and I needed funds. (Right BEFORE Newtown, of course - go figure). The first buyer refused to buy it (sealed boxes, of which he wanted one opened, with plastic bags inside with a wire and lead seal). He swore up and down that it was "remanufactured" - because of the stain of the annealed cases. Bet that moron was sorry when Newtown hit a couple of months later.
