Winchester 5.56 NATO 62 Gr FMJ M855 Penetrator Bulk 150 Rounds WM855150

his 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. For armored or vehicular threats, the penetrator is the bullet for the job.

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.
