This case type also shows up in Spain from time to time so, again, I think we can say this ammo was purchased by the Spanish government.
As far as I recall I haven’t had an original round in my hands, but I have a round with a black solid projectile, unmarked, that shows a double segment crimp on the case neck, so it was probably reloaded (not after firing, but having its original projectile substitued by the black one).
The fired case I am presenting, shows double crimping segments too.
Is the “KE 5429” headstamp identified?
Can this round originally have the double-fuzed pink API projectile shown in my previous thread?
