Here is a real world example of bullet performance beats placement. Old school, no scope, afternoon still hunting. I was hunting with an Ithaca pump 12ga with lightfield slugs. A deer ran past me and I swung the gun and snapped an almost lucky shot. Right in the gut! No joy. As expected. As the deer rans, full gallop, I pumped and got a follow up in the ass. Through the hip, straight line and out the front. Droped on the spot. I hit is again, but; probably no need. Try that with a 223! Try that with a scoped bolt action!
Folks on the www like to talk about how they can finesse a kill with minimum ballistics. There is something to be said for over kill. In the famous words of Elmer Keith: "I cannot be over gunned, because the game cannot be over dead".
