I don't do one shot on anything. If they are moving away, I'm putting another bullet in it, at least. For one thing, I'm not experienced enough to see, or hear, a hit at distance... So unless I happen to see it hump up, or see fur fly, I'm not sure I hit it. For another, I never wanted to track an animal very far. My buddies are very experienced with finding downed animals by the smallest blood trail, and then locating by smell. I'm not that good at it at all. That's another reason why I hunt with buddies, I need the help!!
