Corrected entry: When Lee Van Cleef shoots his rifle at the man escaping on the horse, he is right next to his own horse and a rifle shot that close to a horse would cause it to rear or be startled. The horse is not startled, even when a second time Cleef shoots his pistol. The horse does not react.

Correction: The Colonel' s horse belongs to the "best shot in the Carolinas" a bounty hunter and conceivably served as his horse in The Civil War. It is entirely plausible that his horse was much more used to gunfire than a grain bag. My sisters thoroughbreds (a notoriously skittish breed), barely start when they hear my 12 gauge after a few years' exposure.
