Ammo Overview

Quantity - 500 rounds per case in 20 round boxes
Manufacturer - Federal
Bullets - 62 grain full metal jacket boat tail (FMJ-BT) XM855 steel core
Casings - Boxer-primed brass


The proven M855 ammo that is made to mimic the military specification and does so very well, while still not being contracted ammunition by spec. The steel core projectile is a 62 grain weight bullet that functions very well in 1 in 7, 1 in 8 and 1 in 9 barrels which allow increased performance at longer distances and effective shooting out past 300 yards when dialed in correctly. The Boxer primed brass cases are annealed at the throat and offer easy reloading with great flexibility and can be reloaded multiple times. Talk about a value add. This cartridge offers a great set of ballistics by the numbers with a velocity of 3020 feet per second and 1255 pound feet of energy at the muzzle.

This is the scary “green tip penetrator” your mother warned you about. Be aware that this will be dramatically effective on varmints, in home defense situations and against steel swinging targets. These tend to be ideal targets for this round and while it will work for big game including deer and hogs, it’s a great round for just going out and slinging lead down range at heavy object on stands, or at bottles of water. The plinking capabilities of this round are essentially unmatched with the storied green tip involved. If we didn’t know any better, we’d think the military created the XM855 spec just to have a bit of fun in their off time. Fun is delivered one round at a time through a green tip penetrator.

A: Federal states that this XM855 ammo should have a muzzle velocity of 3100fps from a 20" M16 or AR-15. From a 16" AR-15, you can expect velocities of approximately 2950fps. If you want 5.56 ammo with a muzzle velocity of 3200fps or higher, you should check out Federal XM193.

A: Often, the ammunition inside is exactly the same. American Eagle ammunition is oriented towards sales to non-government/nonmilitary people, while the ammunition packaged in brown boxes labeled Federal is sometimes meant for sale to government agencies or military units. However, both ammunition types are generally made to the same exact standards and could be considered the same level of quality. Sometimes, contract overruns mean that both types of ammunition are readily available on the market.

A: As stated in the description, this ammo comes in 20 round boxes. The full case has 25 boxes of 20 rounds each for a total of 500 rounds.

A: Technically, this is not steel core ammo. It has a hardened steel penetrator in the forward portion of the projectile, and is legal for sale in California.

A: Most ammo has a lead core with a copper jacket. This is an economical way of producing bullets that also offer good performance for a wide variety of situations. Steel core, or steel penetrator like this M855, ammo is meant to defeat armored targets at various distances, but is not as cheap to produce except on a massive scale. Solid copper ammo is meant for hunting or other situations where lead in projectiles is either not wanted or not allowed by law.

A: They are essentially the same, and this is about as close as you can get to genuine Lake City M855 ammo without reenlisting.
