Before getting to anything that is actually important, I want to discuss the number 2000. In addition to being included in the titles of a few notable products, namely Lever 2000 and Windows 2000, the year 2000 is significant for several reasons. Did you know that 2000 is the highest number that can be expressed by only two unmodified roman numerals? It is true. And if you are wondering, 2000 in roman numerals is MM. There was also that little problem titled Y2K, or "Year 2000."

People everywhere were in a panic when they realized that the practice of abbreviating four-digit years to only two digits in computer systems would bite them in the "you-know-where" once the date changed from 1999 to 2000. And when I say people were panicked, I mean people were preparing for the apocalypse. I am sure you remember. As it turned out, the problem was overstated and nothing too Earth-shattering took place.

The number 2000 is really important though, because it happens to be the number of M855 cartridges you get when you order our new Federal XM855CS 5.56 ammunition. Each cartridge contains an SS109 bullet – signifying the fact that each bullet is a 62gr full metal jacket with a steel penetrator and a lead core. These non-corrosive, brass-cased cartridges are boxer-primed, reloadable and ready for use with any AR-15 chambered in 5.56x45mm NATO.

The Federal Cartridge Company, headquartered in Anoka, Minnesota, is a wholly-owned subsidiary of Alliant Techsystems. The company was founded in 1916 and has since become one of the finest names in the ammunition industry. Today, the company manufactures a complete line of rimfire ammunition, centerfire ammunition and shotshells – they even have a production contract with the United States Military. Federal ammunition has been used during multiple Olympic Games in which the U.S. team brought home gold, silver and bronze medals. Pretty high-quality stuff if you ask me.

Like all Federal ammunition, Federal XM855CS 5.56 ammunition is manufactured at the Lake City Army Ammunition Plant (LCAAP) in Independence, Missouri, which is an interesting aspect of the ammunition in itself. LCAAP is a government-owned, contractor-operated munitions facility that was originally established in 1941 for the manufacture and testing of small arms ammunition for the United States Army. Since 2001, it has been operated by Alliant Techsystems and is the largest manufacturer of small arms ammunition for the U.S. Army. But enough about the boring stuff – on to the ammunition you so desperately want to get your hands on.

As noted, each package of Federal XM855CS 5.56 ammunition contains an astonishing 2000 cartridges. But these are not just any cartridges. The cases are loaded with SS109 standard military ball bullets. Each 62gr full metal jacket bullet is constructed to provide for enhanced muzzle velocities. This particular load boasts muzzle velocities that have been observed to travel in excess of 3,100 fps. You may have also noticed that each bullet features a green tip. This signifies the presence of a steel penetrator tip and a lead core. Those bullets with orange tips signify that it is a tracer round. Even more impressive is the fact that this is the same ammunition used by the U.S. Military.
