| After World War II and the decommissioning of the .30-06 in favor of the unsatisfactory 7.62 NATO (308 Winchester) used in the M14 firearm, the military decided that another smaller caliber was needed for our NATO forces. Work began in the early to mid 1950's and there were many prototype/experimental calibers leading to the introduction of the 5.56 NATO or (223 Remington). Some were called .222 Remington Magnum (aka .224 Springfield), .224 Winchester and .222 Special (Stoner-Design). The NATO armed forces finally decided on the .222 Special design (aka .223 prototype) and called it the 5.56 x 45 NATO. The commercial version became the .223 Remington. These .222 Special cartridges are from that testing phase (1954/1956) leading to the 5.56 NATO introduced in 1957 for use in the USA’s AR-15/M16, and later also named 223 Remington for commericial use. |
