Killing deer with a bow
This trick is useful when you playing a season and are required to use a bow to hunt a high point deer that keeps running away from you. Get a gun with a scope. Aim in front of or at the deer (depending if it is moving or not). Switch to the bow and do not move your hunter at all. Aim with your bow and shoot. The same thing can be done at the target range.
