ever since i read that article, i have been trying to keep both eyes open when shooting my scoped rifle. it's not easy, that is for sure. i find that sometimes, i naturally start to switch between which eye i am using. I lose sight through my scope and sometimesi have to close my left eye (not lookin through the scope eye) so that i can gte back on track of where i should be with my right eye (eye looking through the scope).
I'm still in the first or 2nd year of my shooting career, so i'm trying to learn the good habbits before the bad ones start.
