There's a great clip on Youtube -- someone has spliced together scenes from "The Rifleman" with Chuck Connors in which our hero walks down the street and shoots his rifle about 60 times, killing dozens of people. Then he calmly starts to reload.
Must be ‘rabbit bullets’, they multiply.
The other one from the westerns is the guy “fanning” his pistol and actually hitting what he's shooting at. If you're holding the trigger down and pulling back and releasing the hammer with your other hand, you have NO ACCURACY!! The same with Lucas McCain's rifle. The action of levering and firing that rifle from the hip would shift the barrel all over the place.
But it's just a movie (or TV show), it ain't real.
