20 x 50 round boxes packed in a M2A1 type steel reusable ammo can. Winchester manufactured 9mm NATO ammunition part number q4318. This ammo is commercial grade ammunition that is loaded to military specs with 10% higher pressure than standard 124 grain FMJ ammunition, thus it is +P pressure level (but not specifically marked +P). This ammo is excellent for sub machine gun use but will work well in any high quality 9mm Luger caliber weapon.
This is loaded ammunition.
