Gryan I am assuming that you mean your son is actually bowhunting (if not, with only grapefruit sized groups at 15 yds it sounds like he has way to much gun or is simply flinching terribly, but I doubt that is the case). What kind of practicing is he doing? What kind of targets are you using? Many beginners that I help are guilty of shooting their first arrow " anywhere" and then actually get a group by shooting at their first arrow. Thats indicative of not aiming at a spot like on the target, but for some reason they can easily aim at that first arrow. Really I see it all the time. And its only worse on live animals. They simply put crosshairs or pins on " the deer" and let fly with hope and luck.

I would actually recommend you have him start practicing on white cardboard or posterboard that is just blank, something larger than just a standard piece of notebook paper. He needs a large enough blank area that forces him to pick a spot. Have him call out a specific " area" he is going to aim at before the shot. This will help him concentrate on " picking a spot" . And dont let him shoot at the same spot twice as that defeats the purpose. Simply turning large targets over that are blank on the backside will work as well if they are big enough. Once he gets a general feel for " picking a spot" , the BEST thing is to have him start shooting at fullsized 3-D targets. It would be worth your investment in a $60-$100 target like a McKenzie etc. This will truly train him and show him the importance of concentration on an " imaginary spot" . I also recommend he practice on that target while in a stand or somewhere off the ground to get him used to the different shot angle of a treestand.

Once he whacks that first deer, it will not only be worth ALL the work and practice, but he will be hooked for life and his confidence level will SPIKE greater than anything you can tell or do for him. PLUS you will have the most enjoyable hunting buddy of your life!!!
