You're right, get anywhere near the opposite leg and the arrow can indeed bounce out. Think of it ,on a bradside shot you have a 50-50 chance of either hitting rib, or going in between, same on the other side. You think the rib bone slows down the arrow much? You bet it does. Hey I'll take 12" of penetration any day. Thats a dead deer if it's in the boiler room.
