When I was about 9, my dad got a me a Ruger M77 .270 bolt action(only rifle I will ever shoot and still shoot to this day) and when we went to the woods to sight her in I was shooting right handed but rolling my check over so that I was looking through the scope with my left eye. Luckily, my dad said "what the hell you doing boy" before I shot instead of letting me learn the lesson the hard way. I told him this is how I shoot my daisy red rider bb gun and hit every soda can I shoot at. He just laughs and replies "this has a little more kick than a bb gun son." Did one of the many eye dominance tests and it proved that I was left eye dominant. I always thank him to this day for not letting me shoot with my checked rolled over to use my left eye through the scope. He said hell, I didn't have health insurance to pay for you breaking your nose.
