Not an optimum choice, but IMO something on the order of a 230g cast TC moving @ 850fps properly placed would be enough to do the job if you were close enough.

Cast is a monolithic solid and the large metplat does damage, so this would be my choice over a HP or ball and for hunting it would improve the performance by way of penetration.

Consider the 45 Colt cast at 255g and moving 850 to 900fps being used and while not thought of as the best solution, it is adequate. Cast in an acp is not so different.
