 Given the close performance to other cartridges and military acceptance, both the .222 Remington and the .222 Magnum faded quickly into obsolescence, being replaced by the .223 Remington.While the .222 Remington is rarely found in current production in America, its derivative cartridges are among the most popular in the world.In addition to the .222 Magnum and .223 Remington, the .222 has also served as the parent case for the .221 Fireball, the fastest production handgun cartridge.
