7.62 NATO Headstamp ID
OK guys, someone out there knows the origin of this ammo. I have searched on several web sights and have come up with no definite answer. Some say German and some say Austrian (Hirtenberger). Is this ammo German or Hirtenberger? Headstamp reads "7.62x51" at 12 o'clock. At 6 o'clock reads "H21-59". Thanks guys.
