Yeah, the military scientists and engineers seem to believe, and they should know, that the harder the armor, the more speed you need for the projectile. I have read that this similarly applies to hard bone, but that is against the conventional wisdom it seems.


Bone and armor aren't related in those terms. I learned in the late 70's that it takes speed to penetrate steel and hardness to peneyrate concrete. Bone can be broken and or penetrated both slow or fast projectiles and requires a bit of hardness but nothing like concrete. Expanding bullets do not penetrate concrete well at all

Soft bullets will penetrate steal if the velocity is fast enough
