Yo my friend you did recover those deer even if one did run a few yards. Thats what is so nice about a Barnes X bullet! They penetrate the tip will fold back like pedals on a flower and keep on going. To have a good blood trail we need pass throughs in the lower one third of body cavity so it fills up with blood quickly. then it runs out those holes. Try to get a shoulder shot next time don't matter which side or through both and see how great they work![&:]
