Product information ".223 Rem."
The 223 Remington is a rifle cartridge, originally developed in 1957 as a commercial hunting bullet for varmint hunting. The first rifle chambered for it came out in 1963. It has continued to be a popular civilian small game hunting cartridge. Though it finds occasional use on medium game, this is not recommended and is illegal in at least ten U.S. states and the United Kingdom, where the .243 Winchester or similar cartridges are the smallest bore cartridges that are legal for hunting deer.
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.
