I do not mean to sound argumentative but why is that whenever there is a discussion of penetration we usually end up with two opposing camps. One camp, the light, fast carbon camp loves to use Kinetic Energy as their basis to support their use of equipment. The other camp, the heavy, slower aluminum camp always wants to use momentum as their basis to support their use of equipment.

I always see numbers and equations thrown around to support both sides but rarely do I actually see a true comparison test. What do you think would be something trully representative of a live animal short of shooting one itself? Ballistic gelatin? An old shoulder blade saved from a prior deer harvest? Any ideas at all?
