I went over to bowsite to educate myself a little as Big Duane suggested.They seem to be pretty divided on the subject.Where the wind pipe meets what would be the collar bone area on a human.There is a soft ball to grape fruit sized spot that is the area to hit.Some folks recovery rate was exceptional,some were horrible.Everyone stated it was a ground level only deal,20 yards and in for some,10 yards and in for many.
Obviously the person behind the bow is what is going to dictate the end result.
