You have unanswered questions on the forum.  But you can start here:

At the very start there was the .222 Remington. This was uniquely developed (no parent case) in 1950 as a cartridge for varmint hunting. It became known far and wide as a benchrest competition cartridge because it was good at it, and its developers were avid benchresters. It was the first commercial rimless .224 cartridge made in the United States. So, when Armalite, and others, started its Small-Caliber/High-Velocity experiments, this is what they started with. It was clear early on that it wouldn’t meet the Continental Army Command velocity and penetration requirements, so Armalite went straight to Remington, who in turn responded with the .222 Remington Special, which had a longer case body and shorter case neck than its .222 Remington. Springfield Armory concurrently developed the .224E2 Winchester, an even longer-bodied .222 Remington, which later became the .222 Remington Magnum. Springfield dropped out and in 1963, the Remington .222 Special got its designation as 5.56x45 mm and was adopted for use in the new M16 rifle (even though it was already being used). The next year it got SAAMI-certified and emerged as .223 Remington in commercial loadings.
