These are Boxer primed with a 4-stab crimp.
I think I will bang a primer on bright steel to check if corrosive. Assuming it goes bang, of course.
Then reload the case.

I'm with you. I'll save a few of these boxes, just as I have saved other boxes from WW2
I am lucky to have at the moment 3 original full boxes of GermanSmKH 8mm ammo, of the 3 different bullet colors. And I have sealed full cartons of US Cal .30 AP M2 from the 9 plants that produced such cartons during the war. Plus a few sealed boxes of Ball M1
and other odds and ends.
From what I can tell, the chemistry within those cases hasn't betrayed me yet. But this isn't black powder so eventually these rounds will go to heck.
