Mythbusters-Pistol-Shot-High-Speed-Slow-MotionAt the start of the video they did a standard “Neva bin done befo’” claim… Something tells me this has been done several times before even by YouTuber’s who have access to such cameras.  Correct me if I’m wrong though.

What the heck type of range is his filming that on?  I figured he’d have a pristine personal private range, not one which looks like the battle of Fallujah took place between its walls.

Thoughts?
