I'm about 50% successful on frontal brain shots I've made. All of the tuskless have dropped to a miss, one tusked cow faltered but did not drop. Three bulls have not dropped or even faltered, but one was stopped in a charge and turned.

500grs at 2145fps or 450grs at 2190fps.

Bulls are more imune by far from the shock of a close miss.

But a big bore will turn a charge or drop an elephant, I've turned two and so has 500grs, when a medium bore, even one with more velocity and even more enegy just won't. If you doubt this than fire up Buzz Charlton's very informative and fun DVD, "Hutning the African Elephant," and listen for how many times he recites, "...a hunter using a rifle that shoots a 500gr bullet would have dropped this elephants..."

Buzz uses a 416 Rigby and stops a charging cow in the DVD. His narative, "...If I'd have been using a rifle that shot a 500gr bullets, this elephant would have dropped..."
