Energy means BUMPKIS, I can't count how many times I've seen an elk have the spine shocked by a near miss and it drops them after a few seconds it's dragging it's self then it gets it back end back under it and then all of the sudden your back to a fully functional elk because someone though energy was permanent reliable thing, never seen one recover from a 4 inch hole blown through it's lungs from parts of the bullet mechanically shredding it!!
Your comparing testing with a pistol bullet compared to a rifle bullet on big game, I honestly don't understand how someone can make any leap to how any data from one is relevant to the other!!
