.308 ammo in 200 round sealed battle packs. I have four 200 round battle packs available. Manufactured to NATO specifications by GGG, this 7.62x51mm (308 Winchester) ammunition reflects the superb quality of Lithuanian manufacturing. This GGG ammunition is new production, non-corrosive, in a boxer-primed, re loadable brass case. Topping this round is a 147 grain FMJ bullet that will not attract a magnet making it perfect for those ranges that will not allow steel cored bullets. Must be 21 years old. I live near the Julington Creek Fish camp Technical Information Caliber: 7.62x51mm NATO Bullet Weight: 147 Grains Bullet Style: Full Metal Jacket Muzzle Velocity: 2700 fps Muzzle Energy: 2379 ft lbs Case Type: Brass Primer Type: Boxer Primer, Non-Toxic
