fubsy : I was born with 90% sight loss in my right eye,so I would have to answer, my whole life. Handguns are no problem as I have learned to compensate and am comfortable shooting in any manner of correct or incorrect ways. While I will never be a "great" shot, I do get by OK. It's only when I have to shoulder a gun that the problem starts.Anything up to a 30-30 is fine, but because of the unatural feel, anything heavier is a real problem. My real concern is laying out the $$ for a 12 ga, and then not being able to shoot it.
