Looking for 5.56x45 ammunition that packs a little something extra? Then we think you’ll agree that M855 is where it’s at. This military-grade ammo is loaded with 62 grain penetrator projectiles with green-painted tips. The penetrator performs just like a conventional FMJ – until it hits its target. That’s when the seven-grain solid steel tip just beneath its gilding metal jacket kicks into action, ensuring the bullet can pass through barriers as tough as sheet metal at close-to-medium range!
This round’s somewhat heavier bullet will receive the best in-flight stability from a barrel with a 1:9 or 1:8 rate of twist, although a 1:7 twist will do just fine over all but the farthest ranges. More importantly, the M855 bullet is magnetic!
This ammo’s new brass cases are extremely robust because they have been heat-treated. You will notice discoloration on the cases, although it is purely cosmetic. Boxer-primed, reloadable, and ready to rock out of all 5.56 rifles!
