Listen very hard after the shot. You can't take in enough details after the shot. Where was it when hit, which way did it go, where did it dissapear? Don't start eating venison or looking for your arrow yet. I have had three deer pile up (I heard them fall) within earshot from arrow kills in the last two years. Two were under 100 yds and one just over. I have had a few stinkers make it to the next county (or it just seemed like it) after being hit. They make for a long tracking job but all ov them won't go down quick. The sound of a deer piling up within earshot is almost as good of a sound as the broadhead hitting the chest and blasting thru. Listen for it.
