good reminder....in case anyone here hasn't tried it....a deer's carotid arteries and jugular veins are deeper than you think.
you have to cut very deep to the spine on the sides of the neck to hit them....sawing at the front of the throat...even to the spine....will likely only cut the trachea and esophagus which will kill them but slowly and you're gonna sit and hear and see it pull air through the hole in its throat and suffer
it isn't worth the effort
i have in the past, but will now avoid, just walked up and stabbed the deer around 6 times in the heart and backed off....it's quicker and easier and can be done without getting as close and maintaining a more defensive posture....but it's also not worth it
yeah, just shoot it again from 10 yards and make it a good shot, then wait....at close range your 20 yard pin will hit low because the arrow hasn't risen sufficiently yet
