123 Hansen M67 Yugoslavian factory load 2,424 57,900 CUP
I contacted some ammo collectors and figured this ammo had to be high pressure proof loads. I have seen other test of Yugo M67 ammo that was much milder and in line with standard AK ammo. The proof loads are in boxes similar to standard ammo and if people don't know how to read the language it's hard to tell the difference. That article was from years ago.
