The official name for .223 Remington in the US Army is cartridge 5.56x45mm ball, M193. If a 5.56×45mm NATO cartridge is loaded into a chamber intended to use .223 Remington, the bullet will be in contact with the rifling and the forcing cone is very tight. This generates a much higher pressure than .223 Remington chambers are designed for. [3]
Cartridges like the American 5.56×45mm M193 (1964; originally used in the M16), Soviet 5.45×39mm M74 (1974; used in the AK-74, which replaced the AKM), Belgian SS109 / 5.56×45mm NATO (1980; used in most AR-15 systems), and the Chinese 5.8×42mm (1987; used in the QBZ-95) allow a soldier to carry more ammunition for the same weight compared ...

It is currently the fastest production .22 caliber round in the world with muzzle velocities as high as 4,600 feet per second (1,402 meters per second
It appears that this round can drastically improve the performance of any AR-15 weapon chambered to .223/5.56 mm. Superior accuracy, wounding capacity, stopping power and range have made this the preferred round of many special forces operators, and highly desirable as a replacement for the older, Belgian-designed 5.56×45mm SS109/M855 NATO round.
