One possible option is Congo-Brazzaville: Have a look at: http://www.congo-site.net/v4x/tourism/trsmchass.php

I don't know how good or bad the hunting is there though.

Congo-Brazzaville shouldn't be mistaken for it's "dreaded" neighbour: The Democratic Republic of Congo, where hunting possibilities seem to have been an on and off thing these past few years after they officially opened tourist hunting again.

Supposedly hunting is also possible in Gabon, but as Harald Wolf wrote in Hatari Times a few years ago, his hunt was a disaster.
