For the poor performers, my 500 gr hardcast at 1625 fps from a 500 smith lever gun. Ground away to nothing. The sierra 140gr 357 mag did not kill the yakalo well and had to be finished with a barnes from a 45 colt. Granted it was going much too fast from its intended velocity range so this is not an indictment. Also a 44 auto mag 240 sierra was shot into a watusi bull?s shoulder with a mv just over 1600 fps. It thumped the bull good and broke the onside shoulder. It was put down with a 375hh double rifle. The initial shot the bullet broke up and a couple small shards hit the lung and did no real appreciable damage to the vitals. Too fast and big bone so it wasnt surprising. Just pushed to fast.
