I agree with the double lung shot theory for sure as I haven't shot a deer yet with my Bow. BUT what does everyone think of a surgical shot of directly on the neck ? I shot most of my deer with a rifle in the neck and all of them have gone down instantly... can this be done with a BOW ?
How precise can you shoot your bow? A rifle bullet to the neck usually kills with kinetic energy and if it doesn't kill the deer it will temporally paralyze it if it doesn't do any damage to the spinal column. Now with an arrow to drop him in his tracks you would need to hit the spinal column and you only have two large arteries to hit to have a short tracking trail. There are too many ifs for a neck shot. The double lung or a shot a little high and back will hit the liver witch means a dead deer in a short time and you have a much larger target to err on.
