- Q & A
These are the ever-popular green-tipped 5.56 NATO rounds known as M855, although since they’re manufactured by Federal they’re XM855. M855 rounds have lead bullets with steel penetrating cores, and although they are, indeed, designed for superior penetration, they are not armor-piercing rounds. They’re rated by the military for use against human personnel and light vehicles, but since the test for an armor-piercing round involves blasting through 1” thick steel, M855 doesn’t make that list. That doesn’t mean this isn’t absolutely awesome ammo, because it is. An M855 round is capable of punching through steel target plates like nobody’s business and will do some serious damage to your stationary targets. If you want to load your 5.56-chambered rifle with ammo capable of Hulk-like force, M855 should top your list.
These XM855 rounds are 62 grain, which is the standard size for green-tip penetrator rounds. It puts these rounds on the lighter side, making them capable of higher speeds; there’s no doubt this ammunition soars down-range faster than you can even imagine. These are FMJ rounds designed for target practice, tactical training, and plinking, just remember that rifle rounds can travel for miles unchecked and an XM855 round can punch through barriers that would stop most rounds, so have a backstop in place that’s tough enough for this ammunition. Each of these rounds moves with lightning speed with a muzzle velocity of 3104 feet per second and slams into – then through – your target with a muzzle energy of 1326 foot-pounds.
There are 420 penetrator rounds in this box, and they’re loaded onto stripper clips so you can load your gun even faster. Think 420 stripper-clipped rounds will last you for a long time? Wrong. Your 5.56 will eat this ammo so fast it’ll be gone before you can blink, so you might want to consider getting more than one box. Federal manufactures this ammunition at their plant in Anoka, Minnesota. They’ve been making ammunition to high standards for almost 100 years; they definitely know what they’re doing, and these XM855 rounds are proof of that. Get your order in today to find out why XM855 is considered to end-all, be-all of the 5.56 world.
(Although 5.56x45 NATO does fit in a .223 Remington chamber, the 5.56 is a military, high-pressure round and is not recommended for use in a .223 Remington chamber.)

I have two of these, one of which I bought from this website. I got a way better deal here! This ammo has performed flawlessly in my Mini 14 and is pretty good as far as accuracy goes. Stripper clips make it easy to load and who doesn't love to have an ammo can?

- 5.56x45 what is the 45 for I have s/w ar15 that will 5.56 an 223 is the ammo for my gun Posted On: 11/30/2019 By: mike cole
- Hello Mike! The 5.56x45 is the full name of the caliber. The 5.56 designation is the bullet diameter while the 45 designation is the case length. If your rifle is chambered for 5.56, you can use either 5.56x45 or .223. If your rifle has a chamber that denotes only .223, it is not recommended that you use 5.56 ammunition. Joe

- They aid in loading magazines when coupled with a magazine loader designed for stripper clips.
