Product Overview

Winchester Ammo M855 Penetrator ammo is an excellent choice for competitive and recreational shooting applications. This fantastic ammunition is well known to provide excellent results, delivering excellent accuracy and reliability. Winchester Ammo USA ammunition features 5.56mm NATO with 62 Grain and is positive functioning with great accuracy.

This round features the penetrator bullet – you can tell as much by its tip, which is painted green. Inside the bullet’s full metal jacket is a two-piece core: lead in the back, hardened steel in the front. Its steel penetrator tip fortifies the bullet for more reliable passage through hard barriers including wallboard and sheet metal, and at close range it can easily punch 18” deep into ballistic gelatin.

This round’s bullet weighs 62 grains, seven of which are its steel tip. A heavier 5.56 bullet is best stabilized by a 1:8 or 1:9 twist barrel. A 1:7 barrel should serve you just fine if you’re not sniping, but a 1:12 twist barrel will fail to correctly stabilize the heavier bullet.
