I discovered I was a lefty shooter when I was 9 when my day took me to buy a savage over/under rabbit gun. The guy over the counter handed me the gun and I pulled it up to my right shoulder and leaned over the stock to use my left eye to aim. That's when we discovered I was left eye dominant. I've shot lefty ever since that day for 40 years now. When I got into bow hunting, It was not even a question, lefty.
However, I read something somewhere awhile back that you should shoot a scoped rifle with both eyes looking down the scope. I tried this and shoot much better with my riffles. It does not work with archery for me because of my anchor point. I don't think I could even draw a bow right handed.
I do everything else right handed.
