as far as the watusi, they drop easily with a well placed bullet that holds its shape, that said it was remarkable how many of the bullets touted by the "experts" didn't hold shape! with those there was a LOT of shooting going on. and by a LOT i mean tons. with those shooting what we've advocated a total of 2 bovines in two shots. i used a bullet the experts said would be the bees knees and it failed, went and finished it with a barnes out of a smaller caliber. and to your point gary, on animals not even remotely as tough as a cape buff, not even remote, and if the bullet fails on them it would be a tragic disaster on cape buff. the 50 cal hardcast perfectly placed as i did on the watusi would've been an unrecovered cape buff! any expert that wouldn't recommend a monometal solid or punch bullet for cape buff out of a 500L should have his expert card revoked.
