500 Rounds of 5.56x45 Ammo by Federal American Eagle - 62gr FMJBT XM855

Looking for 5.56x45 M855 ammunition? Don’t let the “XM855F” printed on this ammo’s packaging lead you astray. “X” means it’s meant for sale to the commercial market instead of destined for the U.S. Armed Forces, and “F” just indicates the way it’s packaged. This is the real deal, courtesy of Federal Premium!

This cartridge’s 62 grain projectile is an FMJBT: full metal jacket to ensure smooth feeding into a semi-auto’s waiting chamber, boat tail to produce a flatter trajectory downrange. What really makes the M855 round’s bullet special is what’s beneath the tip of its jacket: a seven-grain solid steel “penetrator” core. Its steel component is why the M855 projectile is able to reliably penetrate sheet metal hundreds of yards downrange, and we’re sure you can appreciate why our military appreciates that kind of performance. Under optimal conditions the M855 projectile also has a good chance of breaking in two as it penetrates its target.

If you just want to fire this American-made ammo at the range, we’re right behind you. As you may already have surmised, the M855 bullet will attract a magnet. Not all commercial ranges allow “magnetic” bullets, so plan ahead. The M855 bullet will also probably damage a steel target, and its very best accuracy can only be realized with a 1:9” or 1:8” barrel twist. But so long as you’re not sharpshooting over long ranges, a different rate of twist will serve you well!

This is new production, noncorrosive, Boxer-primed, reloadable and brass-cased ammo. Military grade brass cases such as this ammo’s are heat treated for greater suppleness and better functionality, but they aren’t given a cosmetic polish afterward. It will not affect performance, so don’t worry that this ammo’s new cases a little less pretty than usual!
