.223 Remington 55Gr. FMJ, annealed brass case, 2007 production. Fifty 20 round boxes = 1000, in a cardboard box (no ammo can). This is good stuff, not the hottest in the world but very consistent, clean, and surprisingly tight grouping. Excellent plinking/range ammo. I purchased this case for $399 long before Obama but at the peak of metal prices. Im taking a loss by asking $300. I dont think you can find brass cased ammo for less. SOLD FTF in the greater Seattle area, will deliver within reason.
