I agree with most of what has been posted. I have to ask a few questions though. If we are going to be armed with a rifle that take any animal we might face from any angle, then we are shooting bushbuck and duiker with 458 Lotts and larger cartridges? Also, it does imply that we each carry our own medical kit, fully stocked for whatever injury we might face, instead of the PH having one in the bakkie or one of the scouts or trackers carrying it?

A stunt is a stunt, I would never try to hunt with a marginal firearm for any animal. However, using a firearm capable of stopping a raging elephant from any angle while hunting duiker seems a bit odd to me, I guess. I guess the old cartridges from 7x57 through, and including, the 375 H&H should be dismissed entirely from hunting in an area that holds Cape Buffalo, Rhino and/or Elephant.

Should I leave my 300 H&H at home and just carry the 500 Jeffery for Sable and plainsgame?
