If you haven’t heard of M855 ammunition yet, then don’t get turned off by its alien sounding name. This is military-grade 5.56x45 ammunition, compatible with any AR-15 rifle, and just as good to have on hand for target shooting as it is self-defense.

Look at an M855 round and the first thing you’ll notice is its bullet’s tip, which is painted green. That indicates that beneath the bullet’s jacket is a seven grain steel penetrator core. The steel makes the bullet stronger, so it can reliably penetrate barriers as resilient as steel plating at close to medium range. Because the M855 core’s rear section is made of lead and its front section is made of steel, there is a good chance it will split apart into two pieces and track multiple wound channels into soft tissue.

The M855 bullet weighs 62 grains. That’s a touch heavier than the usual 55 grains, and as such this ammo offers the best accuracy in conjunction with a 1:9 or 1:8 twist barrel. A 1:7 twist will still deliver serviceable accuracy, however.

This magnetic ammo is American-made, non-corrosive, brass-cased and reloadable. Winchester packages all 420 rounds in a new production ammo can, complete with a tight sealing bailed latch, rubber gasket to lock out moisture, and hinged carrying handle. This ammo is also loaded on stripper clips to make loading it into magazines easier.
