The 308 is popular in South Africa and Namibia, probably elsewhere too. One PH loaded the Speer 180s others used the RWS Cone point and H-Mantles, not sure which weight. Either 168 will work well. Another good option is the 130 TTSX this if shots will be longer or recoil might become an issue. I wouldn't hesitate to use the 130 on the larger game you listed but might go heavier for eland. Depending on the length of the hunt recoil can build up cumulatively and is more likely in African hunting where you can shoot as many shots in one day as you do in an entire season in the US.
