7.62x51mm SATO

The 7.62x51mm SATO is a rimless, bottlenecked rifle cartridge used by the United Nations Space Command as standard ammunition in automatic rifles, marksman rifles, and machine guns.
== Overview ==
The 7.62x51mm is a high-velocity cartridge derived from the 20th century 7.62mm NATO round. The cartridge case is made from high-durability polymer, reducing weight by 30% compared to brass casings, leading to a subsequent reduction in the amount of weight carried by individual soldiers. The cartridge offers a high muzzle velocity due to the use of copper thermite gel propellant which is much more energetic than smokeless powder. Standard armor-piercing bullets consist of an alloy core, tungsten-carbide penetrator, and cupronickle jacket, with a standard weight of 150 grains. These rounds have an average velocity of 995 meters per second when fired from a 620mm (24 inch) barrel.
