Anyone that bases the distance they can hit a live deer on their accuracy and group size when shooting a target on a range or in their backyard has not bowhunted long and/or have not had MANY opportunities to shoot at a live deer, or have not faced the various inclement conditions that can considerably reduce the distance that you should shoot.

Not only is the perspective much different and varied in accordance with static field conditions and ever-changing conditions that are not normally present when shooting a target, that live deer, and other deer that may be in the immediate area, is/are going to present you shooting circumstances that an inanimate target does not.
