20 Rounds of 62gr FMJ M855 5.56x45 Ammo by Federal

Looking for a box or five of 5.56x45 M855 ammunition? Look no further, because we’ve got America’s favorite Federal American Eagle in stock!

You may have already fired M855 ammo at the range, especially if you have ever served in the U.S. Armed Forces. If so, then this ammo is exactly what you’re accustomed to. But if you’re unfamiliar with M855 ammo, then the most important thing to know about it is that the bullet will attract a magnet.

Why is that? Well, the 62 grain full metal jacket bullet has got a copper-alloy jacket and lead core. It also has a seven grain solid steel “penetrator” tip beneath its green-painted jacket. The hard steel insert fortifies the bullet so it can reliably pierce barriers like sheet metal (which presents an obvious combat advantage to our nation’s troops). The slightly heavier FMJ also has greater momentum in flight, which helps it to resist wind deflection while you’re firing outdoors and over longer distances.

Obviously, you’re not going to get M855 into a range which prohibits “magnetic” ammo. This ammo is also not suitable for shooting steel targets, as it is going to permanently damage them. A 1:8” or 1:9” rate of twist is considered good for a 62 grain bullet, but 1:7” is acceptable as well.

This ammo’s cases are brand new – not reloaded. They do look discolored, but that is only because military-grade brass isn’t polished after it has been heat-treated for greater durability. This ammo is new, noncorrosive and Boxer-primed. It’s a great way to fire military-grade 5.56 in your AR without having to actually join the military!
