Having had a 338/06, I am very inclined to go w/a 9.3 on my next mid bore, as I think it kicks things up a notch, not that a 33 won't work well, they do also.
I think you are set Alan. Elmer Keith used his 44 that far w/250s IIRC, at less than half that mv....no doubt you are slinging a chunk at a good clip. He would surely endorse a 9.3x62.
