I would not hesitate to hunt DG in Africa with a 9.3x62 or an FN FAL. At the other end, I have used the .585 nyati with 750 grain bullets at 2250 fps on elephant and buffalo. It is fun to give them a big whack, but not necessary, and nothing shoulder-fired will drop them immediately.

However, when lightly armed such as that, I would not provoke elephant charges. And I would take flat broadside shots only on cape buff.
