In respect to this, why do my arrows hit the target at an angle?
When you shoot the arrow up close to your target, if the arrow doesn't come out perfectly straight it will enter the target at an angle. The angle that it enters the target at will determine what you have to do in order to tune the bow. If it enters perfectly straight your arrow and your bow are tuned.
