I have a couple of .30-06 cartridges headstamped “W-W SUPER 30-06 SPRG”. They have pointed FMJ 150gr. cupro-nickel bullets. The envelope they are in indicates the box label read ".30 AN M2 Manf. June 1981 Lot 12SF20"
Then an added note (not on the box) “For export to Greenland for Eskimo hunters”.
Does anyone have more information on this load?
