One property owner in the East Cape told me if I didn't shoot every warthog I saw, he would kick me off the place. They are hard on game and domestic farm management because they dig under fences which allows leopards to move around (note that many game fences are electrified at the TOP specifically for that reason ... but maybe for baboons too?). Leopard are essentially not huntable in most of South Africa. My PH said there's less than half a dozen tags a year and those almost always go to "friends of friends." During the drought many property owners had to supplement with feeding to keep the game going. Needless to say, warthogs gravitated to feeding spots. I found them to be very skittish and challenging to hunt. Both of mine were opportunity knocks while hunting plains game. For them, unless shooting over bait (boring!), it's typically not spot and stalk. Usually spot and shoot quickly. The little buggers don't hang around and they usually see you about the time you see them. Both of mine were taken after stepping out of the truck ... on the same property ... at exact same spot ... two different safaris. The owner wanted them shot and lodge wanted the meat. Second trip after cresting a hill, the owner in back seat said, "There's one with tusks. You better shoot him." Nice boar was running across the road. It stopped in the meadow to wait for three others just long enough for me to step out and drop it in a cloud of dust at 200 yards. "Better reload." Not necessary. I shot him in the neck. PH and owner looked at each other. "In the NECK?!" Yeah. Didn't want to waste the meat. And sure enough it was shot in the neck. I think when shooting at something that doesn't matter, one has a tendency to be more accurate. Lesson learned is force yourself to be "unexcited" when stalking the big one for the wall. Better yet if the opportunity pops up unexpectedly and there's no time to get excited. I spent an hour and twenty minutes on the sticks last year before my nyala finally moved into a brush free window for a clear shot. Not sure if I was shakey from anticipation or exhaustion but the first shot went a bit low. He ran and fell but got up again. Killed him with quick second shot off the sticks running at 100 yards through the heart.
Bush pigs are generally taken at night over bait. I have no interest in that. Farmers usually want to be rid of them. They kill livestock. Very hard on sheep. Baboons are also sheep killers.
