The foot may not be a killing shot but the rear end is. There are large arteries that run down the back leg. If you hit these they will die very fast. Is it the right thing to do? NO...because it's a small target and more things can go wrong. I can shoot an arrow into the eyes blinding a deer then go over and club it to death and no meat will be lost. Is it right to do? Why don't 3D targets have a 10 ring on the head? Why would anyone even argue a head shot is a good shot(most of all with a field tip as in the photo)with a bow is beyond comprehension. Either you just like to start crap or your some macho he-man with something to prove or you have NO respect for the animal. The guys who would do this are the same guys who are slob hunters who don't care about game laws or the animal and would do anything to bring home their deer.
