.223

The 223 Remington (designated as the 223 Remington by the SAAMI and 223 Rem by the CIP) is a rimless, bottlenecked rifle cartridge. It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create a small-caliber, high-velocity firearm. The 223 Remington is considered one of the most popular cartridges and is currently used by a wide range of semi-automatic and manual-action rifles as well as handguns.
In the US Army, the cartridge is referred to as "Cartridge, 5.56 mm ball M193." The 5.56×45mm NATO was also developed from the 223 Remington.
