A little advice from experienced shooters, please...

My son is consistently shooting right of center. His hit is always at or around target height, but always 2-3" right of center. This almost bit him this weekend when instead of getting a heart/lung on a whitetail, he got liver. Still lethal, but less than perfect.

He's a rightie, and I know that there are "typical" mistakes in form that people make that cause these kinds of shots. Does anyone know what the possibilities are? I'm trying to teach him, but I don't know where to go from here.

Thanks, as always.
