Anybody look through your scope with both eyes open?

I get a long converging V when try to look down a shotgun rib/barrel. I am right handed and left eye dominant

I use both eyes open to find the target whilst simultaneously focusing on the crosshairs. The only problems you may encounter is with certain eye dominance.

I agree and I have that problem severely from years of Bullseye shooting.

I grew up keeping both eyes open. For reasons I don't understand, my groups gets smaller when I keep one eye shut while shooting from a bench.
