Winchester-Western U300 NIB Unprimed Cartridge Cases I've had this stuff sitting around for the last twenty years or so. I have four boxes of twenty but one box only has nineteen. It's still pretty shiny for the most part but there is some minor tarnish in spots. This can ship USPS Priority for about $5 CONUS. The twenty year-old price tags say $7.19 / box. Make me an offer.
