Of course most autoloading shotguns are semi and if the firearm got away from the shooter it most likely it would not double. We are missing many pieces of the pie here so we are all just speculating, so far, unless I’ve missed some things on the Net, we still don’t know the young mans size, the exact configuration of the firearm, etc. But I really wanted to address the issue about age . . . is it really germane to the equation? Again I don’t like talking about the death of this person and what his family is going through. It is the age issue that I would like to address. When is it to young for someone, with supervision of their parent or responsible adult, to shoot any firearm? In the Northeast some states restrict youth from hunting big game, while in Mid America youth as young as 12 or so can hunt with an adult.
