I keep both eyes open, but squint my left....Left eye dominant.Right handed
Closing the other (presumably dominant eye) will distort the aiming eye.Dummy me, all my life I was forced to be right-handed and as it turns out I am really a lefty shooting right-handed. I didn’t really figure it out until I began trying to do well at 40 plus yards. You can’t force eye dominance.
I shoot with both eye's open for shotgun, Pistol and bow. I close my left for scopes.
