I was taught to shoot a deer in the lower chest cavity right behind the foreleg in order to destroy the heart and lungs. I have done this with five kills and only one ran any distance before dropping. Recently, someone recommended shooting the deer at the shoulder to damage the lungs and spine. He claims that this shot will drop the deer in its tracks every time. I am a bit leery about this because 1. you have to shoot through the shoulder blade, and 2. if you do not damage the spine you run the risk of the deer running off without a catastrophic wound. I hunt from a stand in Western PA, so most shots are 30 - 80 yards and shot placement is not a problem. Your thoughts?
