Yeah, that’s what I look like when I shoot. You see, I’m severely cross eye dominant. When I shoot pistols, I have to turn my head so that my left eye is over the center line of the pistol.
With pistols, this isn’t a problem. With rifles, I am forced to use my weak eye to aim and my left eye closes automatically so as to not try to ‘take over’. I do not see how anyone can use their left eye while aiming a rifle, but it can be done.
Oleg Volk has an article up at Cheaper Than Dirt on living with Cross Eye Dominance. I like the red dot concept better as I’m used to the idea of keeping both eyes open when you use one (I do this on my Ruger Mark III 22/45 with the cheapo holosight on it).
