I don't think many are going to tell you need the 9.3x62 over the 30 06 for your hunting scenario.
The real question is "do you want it?"
It's a really nice rifle that I'm sure I'd like but I'm busy with young kids and a full life so I really don't want it in a bad way for it's own sake, only if it offers something extra. I've never found the '06 lacking I just try to keep an open mind and learn from others who have experience that I don't have. I've got decent experience with bears but none with a 9.3.
