I found one with a "shoulder shot". The shot was 12 yards broadside from 14 feet up. No bones or cartilage interfered with this shot. You are looking at the exit hole, the entrance was directly accross and the arrow was in the ground. The BH was a Thunderhead which I don't use anymore. It was a double lung and severed the arteries on top of the heart.I watched this deer crash 35 yards from my stand.
I was very proud of this shot. It's one of those green dot shots.
