While they are similar, the cartridges are not the same, with slight differences in the shoulder angle, length of neck. It is safe to fire .223 in a weapon chambered for 5.56, but 5.56 ammo in a weapon chambered for .223 may NOT be safe.


Is 223 Remington the same as 556mm?

yes, except 556 is written as 5.56 caliber (223) Actually, no, it isn't.
