I was always amused by the opening scene of the Annie Oakley TV show when compared to the always necessary bad guy chase at the end of each episode. In the opening, Annie (Gail Davis) is standing on the saddle of a horse running at full gallop and uses a Colt 45 to shoot the center spade out of a 9 of spades card that is being held in a cowboy's hand. The center spade on the 9 card is smaller than the one on the Ace, therefore more of a challenge. However, when they cut to the bad guy horse chase at the end of each episode, she couldn't hit the broadside of a barn. The bad guy usually fell off his horse just from laughing.
Along this line, I always felt bad for the horses in the Westerns with all those pistols and rifles being fired right next to their ears. There had to be a lot of deaf horses on those sets.
A funny scene I recall from a Wyatt Earp TV show episode was when Wyatt (Hugh O'Brien) knocked a bad guy over the head from behind with his long-barreled Buntline Special pistol and the barrel bent down in the middle at a 90-degree angle. He even tried to holster the bent pistol.
Not a Western, but I could never understand why Superman, after standing there boldly with his legs spread apart, hands on his hips and his chest proudly pushed out could take all six shots from the bad guy's revolver bouncing off his chest but when the bad guy threw the empty revolver at him, he always ducked. Go figure!
I'm sure they used some kind of ear plugs on those horses. Watch the opining of the lone ranger. He is galloping on his horse firing his gun directly over Silvers head. They had to have used ear plugs on those horses otherwise there would have been lots of accidents with horses suddenly going out of control from the gun shots.
