I would lean towards the Jeffrey for the history, and if not that then a 416 Remington. I saw both rounds on the shelves of the sporting goods stores in Africa. The Taylor makes a lot of sense except in the case of lost ammo which has happened to me before.

The 416 Remington could be almost as trim as the Taylor depending on the action. The difference between a long action and a standard one is not that great for a rifle of this level of recoil. A magnum action though changes things considerably in cost and bulk especially with a dropped box magazine.
