Giraffe is a good one if you hunt it on a big property with some challenging habit. Like in the mountains in parts of Limpopo. Just hold out for a big black bull.
Klipspringer, yes. In the mountains up top in parts of Limpopo or the Karroo in the East Cape... If limiting yourself to RSA.
Red Hartebeest, eh, to me more EC, like Black Wildebeest.
Common Reedbuck, never saw one in Limpopo.
Eland, doesn't scream Limpopo to me.
Gemsbok. No. Karoo or Namibia.
Tsessebe, yes your probably hunting that on a game ranch almost anywhere you go. Limpopo or Zimbabwe.
Black wildebeest, no. EC/Karroo.
Springbok. No. Namibia or Karroo.
Warthog, yes if you see a good one anywhere. Take it. A truly good/great Warthog is a challenging trophy to find. Never pass one up no matter where it is
Steenbok. I took a 5" plus in Limpopo.
Duiker, same as Warthog and Steenbok. If you see a good male anywhere, take the shot if you can! To me that goes for all the duikers.
