I usually take 4 or 5 deer a year, most with a bow or crossbow I have found that placing your shot makes all the difference. In my experience a heart shot will often run as much as 100 yards so will a double lung shot; but I have found that placing the shot, bow or gun square on the knot of arteries just over the top of the heart will limit the distance run to about 35 or 40 yards max with a bow, and will often drop them on the spot with a muzzle loader. I realize this is a small area and requires a carful shot and a reasonable knowledge of anatomy but the results are worth it.
