Pick your shot, with a premium bullet, and you should be fine on a buff - borderline - but fine. With the new Oryx and similar loads, it behaves a lot like a .375 flanged in its classic load. It would not be a primary choice for elephant. I have always thought a scoped 9.3x74 OU would be a very cool plains game rifle in any of the brush country destinations. It would be decisive on everything up through eland. I have a 30'06 in that configuration, and with TSX's it is equally effective, but that extra 40 - 80grs in bullet weight is interesting.
