223 556

The .223 Remington is a rifle cartridge, originally developed in 1957 as a commercial hunting bullet for small mid-western varmints; with the first rifle chambered for it coming out in 1963. It has continued to be a popular civilian hunting cartridge.
A military version, M193, with a 55-gr full metal jacket bullet was used by the United States Army in the M16 rifle. The 5.56×45mm NATO was also developed from the .223 Remington.
