If I was booking another cape buffalo hunt on price I would still go with Zimbabwe.

But if I was looking for a choice or chance of the biggest, longest horns I would give Tanzania a shot. Can't talk from personal experience though as I have hunted there. But the largest trophies I have seen came from certain areas of Tanzania. Quantity of buffalo being shot may also play a part.

Don't know about Zambia, Mozambique, Namibia, Botswana or South Africa.

The big trophies tend to be where you find them! as lucj certainly plays a part and a smattering always seem to come from all over.
