If I use a shotgun I aim for the head,but if they are more than a few yards away you are going to get pellets in the meat everywhere sooner or later just advise the youngster to aim for the head and if they hit it anywhere then it's a good shot,main thing is they have fun and shoot alot,that is what will get them to go back time and time again,and as they get older then it will be about who made what shot and how far and so on.GOOD HUNTING and enjoy your hunting partners.
