Broadside
Heart-lung: follow the back edge of the near front leg up about a third of the chest height. The heart sits low, just above the elbow. Side-on brain shot: the brain lies low in the skull, roughly halfway between the eye and the ear and a little below that line.
Quartering and other angles
Frontal brain shot: the brain sits low and far back in the skull, roughly level with the eyes and behind the horn bosses. The bullet has to travel down the length of the skull, so the entry point shifts with head height. Low head, aim higher on the face; raised head, aim lower. Quartering away on the body, aim for the far front leg.
Do not
Do not use expanding bullets. Rhino need solids with deep, straight penetration. Hunts are only legal under strict permits in a few countries.
Where they live and the typical miss
White and black rhino live in Southern and East Africa under heavy protection. The typical miss is a brain shot placed too high, into the horn base and sinus.
Darting and conservation
Many rhino hunts today are green hunts, where the animal is darted for veterinary work or relocation. The shot placement for a dart is the heavy muscle of the shoulder or rump.
