if your shooting a slug theres a good chance of it going straight through someone and still being lethal, buckshot and bird shot dont scatter how people say they do, in a house if your shooting a target more than 7 yards away from you that would be considered far, and even then the spread of the shot is nowhere near as wide as a torso, if you miss with buck or bird shot it might go through a wall, if you miss with a slug its more than likely going through a couple of rooms.
