The .222 Remington, aka Triple Deuce was introduced in 1950 by Remington Arms Company (as a completely
new designed cartridge) to compete against the .219 Zipper by Winchester in a market between the .22 Hornet
and .22 Swift. It was first chambered in the Remington Model 722 Bolt-Action rifle.
Many other cartridges hace been designed using the .222 Remington case, sure as .221 Remington Fireball,
.17 Remington Fireball and more recently the .204 Ruger. (.222 REM. vs. .223 REM. below)
