My "GUESS" is that the brass was indeed made by IVI, or whomever makes that now. But the complete head-stamp is not same as military NATO - so is no real reason to believe that ".223 Rem" by IVI, is same as 5.56 IVI NATO stuff. It might be - it might not be - would almost have to weigh a sampling of each, or compare water volume, to know if they are the same or not.
