The .19-223 is a .19 caliber rifle wildcat cartridge. It's the second in a set of .19 caliber rounds created by James Calhoon because of his interest in British sub-caliber rifle trials in the early 1970's.
The cartridge is based on a necked-down .223 Remington cartridge. This gives higher velocity and a flatter trajectory than would be found with typical .223 loads. .19 caliber rifles have thicker rifling than .17 and .20 caliber files, which helps the barrel stay clean longer and improves barrel life.
