In my humble opinion the 9.3 is the better round. You can get factory loads up to 320 gr. It is mild to shoot and when you hit game with it they go all wobble legged and tip over. I shot a 5 pt whitetail with mine a few years ago when he was facing dead on. Bullet took him at the base of the throat and exited at the base of the tail. End to end pass through with almost no bruising and very little meat damage. Try that with a mag.
