Sable (Hippotragus niger).
The challenging, almost aggressive stance of the sable (not unlike a well bred Arab horse) is well known. They are prolific in the northern parts of Mozambique and considered rare in South Africa for local hunters and is rarely shot for meat due to cost. Like the gemsbok the sable is a very tenacious animal which needs to be shot through the heart to prevent a protracted and dangerous follow-up. Definitely a not lighter than 180 gr bullet from a .308" calibre or 170gr from a 7mm.
