As Trigger and others are shooting their guns at the feet of the "Dude" in the saloon, no bullet holes can be seen in the floor until a close up is made. When the shot returns to a longer view, the bullet holes are no longer there.
While Trigger and others are shooting their guns at the feet of the "Dude" in the saloon, the first two shooters fire 16 shots from two guns (one each, 6-shot revolver) without reloading. Trigger shoots 12 shoots between his two guns and then begins to reload (ok).
