I hunt in the hills of ky, if I am hunting a holler and dont want the deer to run down a hill or into a thicket I shoot them in spine or the neck,depending on angle the crease between the neck and shoulder will work to. If the deer is coming strait at you with a rifle I aim at the v where the throat/neck meets the chest. A strait away shot gets a base of the neck shot. Basically I take out the central nervous system and a deer wont go anywhere. A heart lung shot is good but with that said sometimes they bolt like crazy with a heart shot.

hope this helps chris
