Hank, that really sucks.
From experiences at some of the rendezvous I have attended, some of them have a match where a person has to shoot from their weak side. I agree, it is pretty uncomfortable.
At first it was a totally alien experience, but after the first two or three attempts, I found out that I could shoot just as poorly left handed as I do right handed.
The only "cure" I can think about is to have the cataracts corrected.
Or, go with it and get a left handed rifle.
