Take me instead! LOL
If his shooting bothers you then tell him if he can put 5 in the target in a row you will take him. If it were my call to make I would base my decision on how hard he's trying not how good he is. If he is really making the effort and doing the best he can I would take him as long as there are no safety issues. Maybe you could watch him shoot and give him some pointers. Another idea would be to set his stands where he could only get real close shots.
