There is a video floating around a while ago where a very reputable PH shoots every single buffalo immediately after the client does. Every single time. It could have been some understanding between the PH and client as it was never mentioned.Maybe they wanted to avoid un-necessary tracking in the thick Zambezi bush or something? They id take quite a few and with the video perhaps wanted more action instead of searching.

But I would not be happy for a PH doing this on my safari unless it was necessary - ie a charge getting too close or the animal being obviously poorly shot and getting away.

Communication is the key before booking and before hunting to a lot of later issues.

I do remember discussions on shooting elephants - I have never shot one - where a lot of people admitted the PH will shoot immediately after a brain shot being missed - ie if the ele doesn't drop, and will also shoot no matter what if a heart shot is taken.

This story does fit those circumstances.
