Although I have a 9.3, I've never used it on buff. However, the cartridge is so close to a 375 flanged that I wouldn't hesitate to substitute it anywhere I'd use that. Having said that, the 375 H&H family are rather marginal for charge stopping at close range. Clair has it quite right, that's where you want a 450-476 family or even bigger. After all, it's the pf's shoulder and he's used to it. The 375 is great for buff you stalk, not as good for wounded angry ones. I've only once had to deal with a surly buff heading in my direction and I had 70 paces to do it it. You'd be surprized how fast you can reload given sufficient incentive and collective throw-weight counts for something! It was a 375.
This is a topic that comes up uver the fire and the only phs I've met who would prohibit a 9.3 were those who had a highly legalistic view of the (government) 375 minimum regulation.
All that said, I have a little Chapuis 9.3 that will shoot sub 2" groups at 100 yards all day and comes up like a bird gun. It would make a great African one-gun safari rifle.
