Yes, stalked plenty of springbuck over the years, even on farms in the karoo, but not on the farm we went to the last two times. The farmer does not hunt himself at all, a sheep farmer, and he also does not allow anyone to chase the springbuck around for you either. One can see 5km's in every direction, believe me, on that farm no one is chasing anything lol. If there was we could have shot all 130 easily. Some of the shots were over 500m, I was just lucky to have them stop under 120m. (Except for a warthog that I shot at 430m, warthogs do not occur in that area naturally, some escaped from the farm next to his and he said if we see any we must kill them, no matter how small/big they are. They screw up his fences that keeps the jackals out of his sheep camps)
But yes, a lot of farmers do the driven hunt with either guys on horseback chasing them towards you, or guys walking around or even use vehicles or bikes. They can do what they want, I can't care less. But yes, that's not hunting, it's culling.
Edit: Just to add I have not seen anyone wound a animal on these two "driven" trips we went on, but the 5 walk and stack trips we did over the same period animals were wounded. Just because you can get 50m from one stalking does not mean you are going to kill it, crap happens, no matter how good of a shot you are.
