I don't think it's enough to kill someone unless you know a person's vital points - and in this case, I really don't think it's what killed him. But if you use more than one bullet - let's just say ten or so - at once, it's definitely going to hurt.
Of course, it is also possible to make someone go unconscious that way, depending how strong they are.
