A: These cans do not come with any desiccant packs in them.

Posted On: 5/9/2013 By: CO_MF

A: While we don't have any extra spoons (also known as "feeders" which remove the ammo off of the clip directly into the magazine) laying around, we have found that Federal is including at least one of these per each ammo can. This is usually laying on the top of the ammo sleeves, inside of the can. If you do not wish to use a spoon/feeder, the rounds may be easily removed from their clips to be loaded manually into the magazine or stored in your box of choice.

Posted On: 3/26/2013 By: Sidney

A: The 420 rounds are loaded on 10 round clips. These clips are packaged into cardboard sleeves of 30 rounds. The full ammo can weighs approximately 18lbs. These are packed into the ammo can to take up the full width of the can. There is usually enough room in the middle column of the can to add 2 50 round boxes of pistol ammo if you choose to fill the can to its maximum capacity. While out of our control, Federal will include a spoon (feeder) for the magazines if there is an excess supply in the market.

A: This Federal 5.56 ammunition is from a recent production run and should not be older than two calendar years. On previous cans we have noticed most of the brass is stamped with Lake City '11.

Posted On: 2/26/2013 By: Russell

A: This is correct. While the rounds are brass cased with a copper jacketed bullet, steel is used inside the core of the bullet. This will make the bullet stick to a magnet for those ranges that "magnet test" the ammo. This ammo is a great choice for any outdoor shooting range.

Posted On: 1/27/2013 By: Jeff

A: Since the 10rd clips of ammo don't physically insert into your magazine, these will work on any magazine that holds 10 rounds or more. Federal usually includes a spoon, also known as a feeder, that connects the clip to your magazine. From there you may push the rounds off of the clip and into the magazine. If you are shooting a 10rd magazine, 1 full clip from this ammo can will fill your magazine. If you have a 30rd magazine, grab 3 clips of ammo to fill the mag. This spoon will fit on any standard AR-15 Magazine.

Posted On: 2/6/2012 By: Jeff

A: The barrel of your AR-15 should be stamped with either .223 or 5.56. You should check the barrel and not the lower receiver, because the two can be swapped without changing what the receiver states the firearm is chambered in. The two are not the same, because 5.56 is loaded to higher pressures, and only the 5.56 chamber is manufactured to safely relieve these pressures. Using 5.56 in a .223 rifle could possibly result in an unsafe condition that would cause excessive wear and improper function.

A: No, this ammo will stabilize out of a 1/9 twist barrel.

Posted On: 10/18/2011 By: Quicksaber

A: This Federal XM855 ammunition features new ammo cans.

Posted On: 10/18/2011 By: Zack

A: Ammunition can be stored for many years, but it does not "expire" like food. It should be stored in a cool, dry place. The biggest sign that it should not be used or depended upon is evidence of water or other moisture on the ammo or the packaging in contact with the ammo.

Posted On: 10/13/2011 By: Jacob

A: Lake City is a government-owned ammunition plant operated under contract by ATK. It is not a specific brand of ammunition. Federal (FC) headstamp brass can be considered of equal or comparable quality to Lake City (LC) brass. The same goes for ammo, although some Federal ammo may not have crimped primers or sealants on the case mouth.

Posted On: 10/11/2011 By: Dustin

A: The penetration in dirt of these M855 rounds will be no greater than any comparable bullet of similar size, weight, and velocity. They are designed to penetrate barriers such as steel helmets.

Posted On: 10/9/2011 By: Matthew

A: Yes, this Federal M855 ammunition is essentially what the HK MR556A1 was designed to shoot. It will function reliably in any serviceable rifle chambered in 5.56 mm.

Posted On: 10/2/2011 By: Jonathan Humphries

A: This ammo will have a slightly longer max effective range than 55gr due to its higher ballistic coefficient, but will not be as effective at range as 77gr. The same goes for wind drift at range. At close (0-300m) ranges, the differences are minor.

Posted On: 9/29/2011 By: Jason

A: This 5.56 ammo comes in a can that is the same size as a standard 30 cal ammo can.

Posted On: 9/29/2011 By: Anonymous

A: Yes, this ammo comes with a spoon or stripper clip for loading the ammo into magazines.

Posted On: 9/29/2011 By: David Savino

A: The ammo can is approximately 10" by 3 1/2" by 7" and weighs 16lbs. It is a new can with a gasket.

Posted On: 9/28/2011 By: Anonymous

A: Yes, a stripper clip guide or "spoon" is included with this ammo.

Posted On: 9/27/2011 By: Chuck

A: The terminal performance of 55gr and 62gr 5.56 ammunition is very similar - that is to say, not consistently impressive. Both are designed to be land warfare legal and in the case of 62gr M855, penetrate specific steel barriers at specific distances. You would be far better off with fragmenting ammunition. Either 40/45/52gr ballistic tip/HP or 75/77gr BTHP ammunition would work much better for coyotes.

Posted On: 9/27/2011 By: Greg

A: Yes, because these Federal XM855 cartridges were loaded on a military production line, the primers are crimped in place. In order to reload the cases, the primer pockets will need to be swaged.

Posted On: 9/27/2011 By: Dallas

A: One "spoon" used to feed rounds from the stripper clips to the magazine is included with this can of ammo.

A: ATK (parent company of Federal Ammunition) currently operates the Lake City Ammunition Plant to supply our military with mil-spec ammunition for service use. This particular batch of XM855 ammunition according to ATK, "had ballistic variations that were outside of mil-spec". This XM855 ammo which performs great was sold to the civilian market providing a great value to AR-15 shooters. This XM855 ammo provides great penetration and is highly accurate. Additionally, this product is great for long-term storage as it comes packaged in a sealed ammo can.

Posted On: 6/1/2011 By: tyler

A: Green tips are utilized by ammunition manufacturers on 5.56x45mm cartridges to identify it as an M855/SS109 cartridge. The green tip on the projectile does nothing to alter its performance and is simply a color indicator to easily identify it as an M855 round. The M855/SS109 cartridge contains a 62 gr steel-core projectile and is often dubbed the "penetrator" round named for its ability to penetrate through steel plates. At 600 yards, the M855 bullet is designed to penetrate through .135" steel. At 50 yards, the penetration capability is between .25-.5" with a minimum steel hardness of 1010 according to MIL-C-63989.
