I’ve seen plenty of people struggle with “different-eye” dominance, if that’s what it can be called.
The son of a friend of mine probably was a natural lefty when he was little. But as he grew up he learned to write, throw, etc. etc. with his right hand.
His dad wasn’t a hunter or shooter so I have taken them both out on occasion just to plink. The first time the young man raised the rifle, he was holding it righty but cramming his head down on the stock to get his left eye to the scope.
I told him to go ahead and hold the rifle (.22 mag) left-handed. He insisted on going righty but at times when I would glance over he would be cramming his face down there again without even realizing it.
I am right handed but should have been left handed. I am left eye dominate but it is mild. I trained myself to practice the combos until I was good at it. I trained my daughter now 34 years old and son sonn to be 33 the same way from early childhood. I’m a really good shot with any firearm. My son is as good as I am. My daughter kicks our butts. I am already working with the two oldest of my five grandkids who are female 6 and male 5 with pellet pistol and scoped pellet rifle. They are natural shooters.
