We all have our excuses about why we miss flying birds when we’re shooting our shotguns, but cross-eye dominance doesn’t have to be one of them.
As a child, and even into young adulthood, I had a strong right-eye, which matched my right-handedness. Unbeknownst to me, my eyes changed as I aged. Now my left eye will take over as the strong one if the right one is fatigued. The issue doesn’t bother me at all as I look through the scope atop my Sako Hunter rifle. When I need both eyes open, to point at and hit a bird is when I’ve encountered difficulty.
