Is there a difference between 223 caliber and 556 mm?
Yes there is a difference. They are physically the same size casing, but the 556 military rounds' chamber pressure is ~10,000 psi higher then 223. Military rifles generally have chambers with a different throat configuration than normal sport 223 rifles. This being said, I would not recommend shooting 556 unless your rifle was designed for the higher pressures.
Are 223 and 556 the same?

Is 223 Remington the same as 556mm?
yes, except 556 is written as 5.56 caliber (223) Actually, no, it isn't. Although the dimensions match, the military 5.56 cartridge differs from the civilian .223 in several aspects, such as the neck angle, casing thickness, and chamber pressure. A general rule of thumb is that .223 Remington can be fired in a 5.56 chamber, but 5.56 ammo should not be fired in a dedicated .223 chamber.
