This 5.56x45 cartridge by Winchester isn’t your run of the mill FMJ. It’s an M855, also known as the SS109 or “penetrator.” The penetrator projectile’s slightly greater weight gives it a higher sectional density than a conventional 55 grain bullet, but that’s not the only reason why it penetrates so well. This bullet’s green tip indicates that it ends in a seven grain steel spike, which enables it to reliably pierce a 0.12” thick sheet of steel well beyond 600 yards.

This NATO spec cartridge offers all the high quality components that you should expect from a revered manufacturer like Winchester. This round features a reloadable brass shell casing, drawn and tapered to specific dimensions for unfailing feeding, chambering, and extraction. Its new-fashioned Boxer primer won’t permit corrosive salts to accumulate in the chamber and bore, and its propellant burns up clean to deliver consistent ballistic performance.

Please Note: While they share the same dimensions, the 5.56x45 is loaded to a higher pressure than the 223 Rem. Do not fire this ammo in a weapon that is chambered solely for 223 Rem.
