Product Overview

Winchester M855 5.56x45mm NATO ammunition delivers the reliable performance that shooters and hunters depend on in a 62-grain full metal jacket load. The M855 round—also known as the SS109 Penetrator—is a time-tested choice for AR-15s, patrol rifles, and standard-issue platforms. Whether you're zeroing at the range, training on steel, or hunting varmints, this brass-cased, reloadable ammunition offers consistent ballistics and dependable ignition in a cost-effective package.

The 62-grain full metal jacket projectile combines velocity and penetration characteristics that have made the M855 a go-to round for decades. You'll get 3060 feet per second of muzzle velocity and 1288 foot-pounds of energy at the muzzle—figures that translate to flat trajectories and reliable terminal performance downrange. The full metal jacket design resists deformation, making it ideal for barrier penetration and controlled expansion scenarios where depth matters.

Winchester backs this ammunition with quality brass casings that handloaders can recycle, stretching your investment further if you're into reloading. The 300-round cans are convenient for range days and training sessions, and the case structure—three cans per case—makes it easy to stock up or split orders with shooting buddies. This is workhorse ammunition: no frills, no surprises, just reliable 5.56 performance you can count on.
