RE: Dominant left eye/right handed
I struggle with eye dominance. The only places where it is a real drag is pistol shooting, (which I can shoot either hand) and bow. Archery I don't think I can change over. But it has caused me to miss boar with a bow before. Cause my left eye is struggling to pop open when he was running around towards me.
Not much you can do. If she can, try lefty with rifle or whatever your teaching.
