The .223 Remington is a sporting cartridge with the same external dimensions as the 5.56x45mm NATO military cartridge. The .223s are loaded to lower pressures and velocities compared to 5.56mm. Due to its lower pressure, you can safely fire .223 Rem. ammunition in a 5.56mm chambered.
Note, while the 5.56 runs a bit higher pressure, any 223 rifle is going to be able to handle it, heck these same rifles are rechambered in 22-250 and have no problem and that is a LOT hotter. You may use .223 in any rifle chambered for.556, but do NOT use .556 in any rifle chambered for.223.

While external 5.56 NATO and 5.56×45 case dimesions are the same as a 223 Rem, internally they can vary from manufacturer to manufacturer, just like 223 Rems so there is really no NATO, military, or SAAMI specification for internal dimensions.
No, they are NOT the same. The 5.45×39 is a Russian attempt to make a similar round to the 5.56×45. 5.45×39 is not the same as 223, 5.56×45 is the one that is often interchangable with 223, but it is a slightly differant round, and is normally not considered safe to shoot 556 in a gun that is.
Summary: Instead of there being two or three or four possible chambers (.223 Rem, .223 Wylde, 5.56mm Noveske, 5.56mm NATO) and two possible pressure levels of ammunition (.223 Rem and 5.56mm NATO), there are a nearly infinite number of points between the extremes. This can result in differing pressures with the same ammunition.
556 will shoot 223, though usually 223 won't be quite as accurate in those guns because 556 generally has a looser chamber. However 7.62 is not the same. 308 rifles can shoot 7.62×51, but not the other way around. And don't even think about interchanging7.62×39 or x54R.
