Will, who is an infrequent visitor here, iirc, but active on AR, and whose name is Bill Stewart, has succesfully used a 416 Taylor for at least several elephant.

It would be fine for buff as well.

Keep in mind that it launches a 400gr bullet at greater velocity than the 450/400NE rounds and at greater velocity than the original 404 loadings, and they were plenty adequate for DG.

All that said, there is something to be said for rifles for which you can probably scratch up ammo in Africa should you need to.
