Alan Moon has a double in that calibre. He may use it on scrub bulls, or maybe he uses his .470.

I would assume it would kill them, but as the others above have said .....

I just used my 9.3x74R - 286 gr bullets at 2170 fps on cow buffalo and a scrub bull in non-threatening situations it killed OK. Maybe next year I will try it on a big bull and see. The bi bulls are a lot larger and heavier than the cows.

Have to see if I get up there next year first of course.
