Headspace guages dont check ammo. It is used to determine headspace in the bolt and barrel extenstion, and it is better to use a USGI 5.56 field guage to check headspace in an AR15.
ETA, yes if it is a case headspace guage it is ok to use on a .223 round. |

If this is a case not a chamber headspace gage then yes you can check loaded 5.56mm rounds. The differences between .223 and 5.56mm are in the chamber so the 5.56mm cartridge can be loaded to a higher pressure.
