It allows you to properly train to put your shot groups in center mass, which for the untrained, is the best kill shot. Remember, all self defense training teaches you to use deadly force only if YOUR LIFE, or your families, is threatened. It's serious business, because you can't recall a bullet after you've pulled the trigger. I like how you suckered us to answer in the wrong context of your question. You first posted targets, then changed it to photos. Cute trick.
