I am to lazy to deep think much about how the energy of a given load relates to killing Alaska's big game. All I am concerned about is whether my loads have "the right stuff", which is, sufficient accuracy for my shots at what ever I am hunting, shot placement, penetration and wound channel. Those are things that I can relate to easily because I can see evidence of them when I make a gut pile.
I do think energy has a role some where in determining if you have enough for the task at hand. But, I'm not ever going to figure it out.
