With iron sights?
.357 with iron sights at 65 yards (195 feet) isn’t impossible. Notice he said he hit him in the thigh. At that distance, aiming for the head on iron sights likely would’ve resulted in a hit below the waist. It’s not natural to aim over a target, but at that range with a revolver, he could make a kill shot. He’d have to understand physics though, and in a shootout situation, most people aren’t busting out a scientific calculator.
