not the most intuitive thing in the world to shoot both eyes, extremedooty.
try bringing up the gun and aiming with one eye, then while holding it there, open the weak eye too. you need to be comfortable with the fact that there are two sight pictures going on.
i switched to two-eye shooting trap, and i did it by doing what i just said, and most of the time i would squint my left eye alot so it was still open but it din't see as well as the right eye. oever a few weeks, i let that squint let up a bit.
that being said, i continue to focus on target, not sights. i lose a tiny bit in overall accuracy, but i'm comfortable with my acquisition and shot placement. i think it would be weird for me now to shoot with just one eye, focusing on the front sight.
