I am left-eye dominant and right handed. Shooting rifles I use an eye patch over my left eye. This is the only way I have been able to clearly see through a scope.
Using a shotgun, I can quickly close my left eye during the shot while wing-shooting.
My problem stems from the fact that I can close my left eye, but not keep it closed for any duration. This is why I use the patch for shooting a rifle.
I have been working at keeping my left eye closed during my range visits while shooting my handgun. Tonight, however, I think I have decided to try: 1. Shooting with both eyes open, or 2. Aiming with my left eye while shooting right handed. I think either of these 2 methods will be easier for me. Especially #2.
