History of the .223 Remington and *5.56 NATO* cartridge:
The .223 Remington was introduced in 1957 as an experimental cartridge for the M4 (AR-15) rifle, as the United States forces was looking to replace the 7.62x51mm NATO* (308 Winchester) with a lighter recoil cartridge with less range for closer combat situations.
In 1964 it was adopted by the United Stated Army as the 5.6x45mm Ball cartridge: M193. Shortly after the United States Army adopted the 5.56 NATO cartridge, Remington introduced the 223 Remington to the general public for the sporting and hunting industry.
In 1977, NATO* countries signed an agreement to select the *5.56x45mm (5.56 NATO) cartridge to replace the 7.62x51mm or 7.62 NATO* cartridge; however, due to the devastating wound damage of the 55 grain M193, it was decided to use the Belgian 62 grain SS109 projectile, which was soon standardized as the official NATO* cartridge. The .223 Remington and 5.56x45mm NATO* are not actually identical, although, the outside case dimensions are approximately the same, the 5.56x45mm (5.56 NATO) has a thicker walled case and is usually loaded to higher pressures than the .223 Remington cartridge.
Because of the higher 5.56x45mm (5.56 NATO) pressures, it is best not to use the 5.56x45mm (5.56 NATO) cartridge in a rifle chambered for the lower pressure .223 Remington cartridge.
*NATO is an acronym for the North Atlantic Treaty Organization, an alliance of app. 30 countries started after World War II, which includes the United States, most European Union members, Canada, and Turkey.
* 5.56 in the 5.56 NATO refers to the diameter of the projectile 5.6mm or 22 caliber (app. .224″)
*45mm in 5.6x45mm refer to the case length of 45mm ( app. 1.75″).
