None of us know the extent of your injury, and the 9.3x62 is probably the best option if you can handle it...but it still generates a bit of recoil by some folks standards...
Try it, but if you cannot shoot it comfortably and pain free, then I would suggest a 30-06 or a handloaded 7x57 for even less recoil..
Proper bullet placement and a proper bullet with either will kill any animal on this planet, even elephant..Not my choice but I have not had two surgerys on my shoulder as you have and I am not too recoil sensitive. I have killed buffalo with both the 06 and 7x57, and both did very well for me.
I would rather a hunter shot a 7x57 well than a 470 poorly on all DG...
