Adopted by the twenty-nine member nations of NATO and one of the most popular civilian rifle calibers, 5.56x45 ammo is entering a sixth decade of official and recreational use. Globally favored for its cost to benefit ratio, the caliber uses almost a minimum of components from brass for casing to bullet weights and powder to deliver a hypersonic round that can be quite devastating at close to medium ranges. Though still selected for small game hunting, the 55 grain FMJ round is predominantly a target and civil defense option. This one by Winchester leaves the muzzle at 3270 feet per second and is moved along by 1306 foot pounds of energy. Ideal for competitive matches, it delivers reliable performance out to 300 yards and in precision rifles is often pushed out to 600 yards or more.

Because of its widespread military adoption by almost 30 nations and popularity with civilian shooting enthusiasts, the 5.56 NATO cartridge is one of the most produced calibers in the world. Therefore, the reputation for consistency associated with the Winchester “white box” is a welcomed comfort to shooters wanting less wait-and-see and more see-and-hit performance from their ammunition. As always loaded on quality, reloadable Winchester brass cases, these 180 rounds offer post facto value to shooters who handload.
