OK...Pictures are nice, but really do not tell the story of what each was fired into and the range to the target. I have shot many rounds of the Hirtenberger 7.62 NATO ammo and have not noticed any difference on the target from LC ammo.
It "could" be different/more effective. It "could" be that the German bullet pictured was fired into a more resistant medium or struck a significant bone like a femur.
Anyway you slice it, Ball ammo in any caliber will not be as effective as a decent soft point in that same caliber (on soft targets).
