 CONT: During the OK Corral gunfight, Doc Holiday fires three shots  from the same shotgun without reloading. While the second and third  shots do in fact produce the same injury to the cowboy, they are  completely different shots. With the first shot we see Doc point the  shotgun to the air and fire, making the horse rear up. In the second  shot Doc shoulders the shotgun, aims down the barrel and fires.  While the last shot shows Doc running sideways while holding the  shotgun almost at his hip.
