i tried these tri ball things and wasnt pleased. I took a 50 yard shot at a doe and almost lost it. one ball missed the deer, one was just under the skin on the shoulder blade, and the other one lucky enough hit the lung and heart. I myself dont like them or buck shot in general. Just me though. Its seems like too big of a chance to injure the deer.
