The cartridge i have in front of me was fired from a .223 M14, known as a mini-m14 because of the fact that a military issue m14 fires 7.62x51 NATO.
The .223 may be almost identical (some say it's different, but by all that much) to a 5.56 but the .223 was originally designed to take down really big game animals. The .223 offered hunters the ability to take down an animal with less bullets and more force. Hunters are actually vital to ecosystems in some places, where population control over problem species needs to be maintained. Not to mention it's potential uses in extreme law enforcement and security for high risk events such as the olympics. It is in some cases interchangeable with the 5.56mm so it could be used with some 5.56 rifles. the .223 round is considered an assault rifle round, but banning it would cause semi automatic weapons to be affected too.

Your statement about the .223 being designed to hunt large game is completely incorrect.The opposite is in fact true the .223 was designed as a varmint round so small game coyotes,wolves things of this nature you can hunt deer with one but it is not the ideal round for that role and it not a very good round for large game.Against a human being either round is highly effective and likely to cause death or very serious injury.I don't know where you got your information but it is wrong. No .223 or 5.56mm round is a long a a pinke either unless you have tiny fingers my pinkie is about 3 inches long maybe you mean the casing and the bullet.A .233 or 5.56mm is about the length of an AA battery.
Now the 5.56x45mm and the .223 are almost exactly the same in most respect they have a differences the inner wall of a 5.56mm case in thinker allowing for higher pressures the cambering is slightly different the leade of a .223 chamber will be 0.085 on a 5.56mm round the leade is 0.162 both rounds will fit in either chamber but it would be un wsie to use military grade 5.56mm rounds in a .223 chamber.
