I think people that are very ambidextrous might have the ability to shoot with either hand and eye, but if a person is say RH and right eye dominate the chances of being able to shoot with the other eye would be slim to none. Myself, I'm some what ambidextrous. I write LH, but play most sports RH, except tennis I don't have a back hand, I just switch hands but have to serve RH, 2 forehands. Hockey, Baseball, golf all RH, soccer I can kick with either foot but better with my right. Working with tools I'm equally bad with either hand. So I think that when dealing with young people when first starting to learn to shoot, first thing you have to figure out is what eye dominate they are. Just giving a kid a RH gun to learn on because they are RH may be setting the kid up for a really discouraging time, they might be opposite eye dominate. I know, when I was young and first learning to shoot .22 because I was LH just like my brother I was being taught to shoot LH, couldn't hit the broad side of barn door. then my brother says hey try it RH, what a revelation.
