Springfield Armory’s Earle Harvey lengthened the .222 Remington cartridge case to meet the requirements. It was then known as the .224 Springfield. Concurrently with the SCHV project, Springfield armory was developing a 7.62 mm rifle. Harvey was ordered to cease all work on the SCHV to avoid any competition of resources.
Eugene Stoner of ArmaLite (a division of Fairchild Industries) had been advised to produce a scaled-down version of the 7.62×51mm NATO AR-10 design. In May 1957, Stoner gave a live-fire demonstration of the prototype of the ArmaLite AR-15 for General Wyman. As a result, CONARC ordered rifles to test. Stoner and Sierra Bullet’s Frank Snow began work on the .222 Remington cartridge. Using a ballistic calculator, they determined that a 55-grain bullet would have to be fired at 3,300 ft/s to achieve the 500-yard performance necessary.
Robert Hutton (technical editor of Guns and Ammo magazine) started the development of a powder load to reach the 3,300 ft/s goal. He used DuPont IMR4198, IMR3031, and an Olin powder to work up loads. Testing was done with a Remington 722 rifle with a 22″ Apex barrel. During a public demonstration, the round successfully penetrated the US steel helmet as required, but testing showed chamber pressures to be excessively high. Stoner contacted both Winchester and Remington about increasing the case capacity. Remington created a larger cartridge called the .222 Special. This cartridge is loaded with DuPont IMR4475 powder.
During parallel testing of the T44E4 (future M14) and the ArmaLite AR-15 in 1958, the T44E4 experienced 16 failures per 1,000 rounds fired compared to 6.1 for the ArmaLite AR-15. Because of several different .222 caliber cartridges that were being developed for the SCHV project, the .222 Special was renamed 223 Remington. In May 1959, a report was produced stating that five- to seven-man squads armed with ArmaLite AR-15 rifles have a higher hit probability than 11-man squads armed with the M-14 rifle. At an Independence Day picnic, Air Force General Curtis Le May tested the ArmaLite AR-15 and was very impressed with it. He ordered a number of them to replace M2 carbines that were in use by the Air Force. In November of that year, testing at Aberdeen Proving Ground showed the ArmaLite AR-15 failure rate had declined to 2.5/1,000, resulting in the ArmaLite AR-15 being approved for trials.
In 1961, a marksmanship testing compared the AR-15 and M-14; 43% of ArmaLite AR-15 shooters achieved Expert, while only 22% of M-14 rifle shooters did. Le May ordered 80,000 rifles. In July 1962, operational testing ended with a recommendation for adoption of the ArmaLite AR-15 rifle chambered in 223 Remington.[5] In September 1963, the 223 Remington cartridge was officially accepted and named “Cartridge, 5.56 mm ball, M193”. The following year, the ArmaLite AR-15 was adopted by the United States Army as the M16 rifle and it would later become the standard U.S. military rifle. The specification included a Remington-designed bullet and the use of IMR4475 powder, which resulted in a muzzle velocity of 3,250 ft/s and a chamber pressure of 52,000 psi.
