"Behind the shoulder" takes in a lot of territory, some that can result in quick kills, some that might not. I prefer to hit them low and tight behind the shoulder, about in line with the back of the front leg. That will either punch the heart or disconnect it whlie also trashing the lungs. Never had a deer hit like that go farther than maybe forty yards, and they are literally dead on their feet. Most fall within twenty or thirty feet, and they don't get up. A couple of times the heart has actually rolled free from the other viscera when I opened the chest. A deer shot high only through the lungs, can go quite a ways because the heart's still pumping and some of the lungs might still be functioning. Slow bullets don't fragment and throw bits of stuff about like high-velocity ones do so shot placement is a bit more critical, I think.
