My right eye is useless, been that way for65 years at least. I am right handed but have to shoot lefty. I'm just as fast with a righty bolt as most righties. I've tried left hand bolts and no way can I do it. Probably if I had a lefty from the day the problem was found it would work. In fact I just picked up a Rem 700 BDL RH. Start the munchkins off early with the RIGHT tool and stand back and smile..
