It's the ammo seller using that 5.56/.223 label, not the ammo manufacturer.
There is a difference, nato brass well be thicker and have lass volume than .223 brass. 5.56 chamber has a longer leade. 5.56 well normally run higher pressures.
For all practical purposes they are the same with minute differences.
