Winchester - Full Metal Jacket M855 - 62 Grain 5.56x45mm Ammo - 600 Rounds

You’ve got AR-15 fever. The only cure? Ordering yourself 600 rounds of Winchester’s NATO spec 5.56x45 M855 ammunition, loaded by none other than the Lake City Army Ammunition Plant in Independence, Missouri!

This round is loaded with a 62 grain FMJ – a little weightier than usual, which in turn promotes more accurate long-range accuracy as well as the higher sectional density requisite for deeper penetration through soft tissue.

Importantly, this round’s FMJ will attract a magnet. That’s thanks to the green-tipped M855 bullet’s steel “penetrator” core, which deserves its name because it equips the bullet to pierce sheet metal and other resilient barriers several hundred yards downrange.

Lake City exclusively loads new production brass cases. These rounds’ cases are a little smoky colored around their shoulders, which is a cosmetic side effect of the heat-treatment process the manufacturer employs to make brass more supple and durable. Once you’ve popped out this ammo’s non-corrosive Boxers, you’ll have just what you need to start handloading!
