Federal - Full Metal Jacket Boat Tail XM855 - 62 Grain 5.56x45mm Ammo - 500 Rounds

This 5.56x45 cartridge by Federal is designated as an XM855 (the “X” prefix simply means it’s not meant for military use). As an XM855, the round’s 62 grain projectile has a green tip that indicates its lead core is strengthened by a steel penetrator. The bullet’s design is built to penetrate barriers like steel plating and light body armor. This round’s bullet further sports the full metal jacket that’s indispensable for high volume shooting, as it prevents rapid bore fouling, as well as a boat tail design. With its tapered base’s superior ballistic coefficient you’ll find this round’s bullet’s trajectory to stay flatter and deliver greater energy upon impact downrange.

Federal’s American Eagle ammo is cost-effective, but still desirable for the consistent quality it exhibits. You can count on these 500 rounds’ very standardized components to give unvarying performance as you’re enjoying your rifle, and their brass casings in particular are worth hanging onto for the multiple handloading opportunities they represent.
