Well, I'm just the opposite of you (right handed and VERY left eye dominate) and couldn't change either.....until.....I had a medical problem on my right side and my doctor gave me the option of changing or giving up shooting (not an option at all). Within 3 months I was shooting better than I had ever shot before the switch and I've been shooting for more years than I want to admit to! To do so would reveal my real age...LOL I had the right motivation...LOL And since it was a "do or die" situation the mental conversion was really easy.
I even hunt left handed now and harvest far more ducks & geese than before...yum!
Hunting white tail, no doubt.

Now that I'm laid off, and have time on my hands, I'll give it a go as you have. I'm only 54 and looking to see if I can serve in the US military. Wish me luck.
