The most common shot taken on elephants today is NOT the head/brain shot. It still remains behind the shoulder, aiming for the heart and lungs. And I'll reiterate what Rich Baker and others here have posted for you, which you tend to ignore. A bow setup with a KE of 105 lbs or more is an effecient means of killing an elephant. And hunting elephants is an effecient means of managing that species' populations.

Listen man, I've spent three months hunting and guiding in South Africa, I've also attended Professional Hunting classes. I'm a biology major at UWS, and have studied effective population management practices in South Africa. If anything, South Africa has got a good idea of what's going on. Look at the recent increase in cheetah, white rhino, black rhino, and elephant populations.
