Being able to reliably hit a very small target at 70 yards at full draw is exactly what I would want for hunting. That game is easily spooked and can likely evade you better than you can chase it. Why in the world would you want to get any closer than necessary and be moving while attempting to shoot it?

Not to mention that his 10 shots at the beginning of the video are no where close to full draw. I'd suspect that even if he did hit an animal with hide that it would not be a lethal shot.
