I have the same shooting deal and have made the switch and find that I can shoot as well as when I shot right handed.I have a bench gun with left bolt right port,and a Browning SS Stalker in 300 WinMag.Also shoot a left hand Browning 525 shotgun and have made that switch as well.My problem started with eye problems that led to a cornea transplant. I started shooting #1 Rugers for the left side.You can do it if yuo put your mind to it. Good luck!!!
