I wish I had, but not yet. I did find a picture of a 1960 DA NATO cross shell. It's zero crimp with no primer sealant visible at all. The 1970 I have is boxer primed.DI5Hey just picked up some Surplus stamped with the Nato Cross and DA 61.
Seems to be Dominion Arsenal, Québec, Canada......
Anybody have experience with this stuff?
