I've heard on this forum several times that there is an "empty space" below the spine and above the lungs. They say that if you hit them here you won't kill the deer. I don't see it. Is this drawing incorrect, or is that empy space just a myth? Or could it be that high lung hits don't leave good blood trails and these deer die but are not recovered?
