I'm left eye dominant and have preferred shooting rifles (right handed models) left handed although I can shoot both ways. When I took up bowhunting I tried it from the left but no way did that feel good. Maybe if I'd started shooting at an earlier age but at that point it was right handed and learn to use my right eye. It didn't take long, a few winks and blinks, and now its pretty natural. Actually it has helped me become more comfortable shooting rifles from the right side. I may see which way he feels best shooting a bow.
