I'm one of those oddball shooters,
when i'm shooting with a pistol, i shoot right handed, both eyes open and but aim with my left eye. When i hold up a gun and put it on target, i close each eye to see which one it lines up with, and everytime, i've lined it up with my left eye.
but when i shoot a rifle, i shoot right handed, and when i bring my rifle up i automatically sight it in with my right eye, and still shoot with both eyes open. It's quite odd.
