There are some african countries that state the 9,3 as a minimum, and I'd like to know which?

As to caliber, the diffrence between a .375 and the 9,3 is merely academic when it comes to solids? I've heard the .375 is marginal, but still capable of putting down an elephant. Would a 9,3mm be that differen?

When it comes to buffalo I agree to a certain degree, as they're primarily hunted with softs.. However, shot placement is the more essential..

To shoot the .470 reliably I'd have to get some sort of scope.. I can't say I fancy a heavy recoiling rifle with s scope, and the stock being to low at the same time..
