.223 5.56

[Pgabriele]

I know this is a newby question but I have never been told the black and white answer. Is .223 and 5.56 completely interchangeable in all rifles or its there some sort or catch to this?

223 firearm = 223
556 firearm = 223 and 556

What is the issue when loading 5.56 into .223 what makes them incompatible
