Briman - I've had the exact opposite experience. With the 300win mag I have NEVER seen ANYTHING: elk, antelope, or deer get up after it was KNOCKED down, as opposed to running off and LAYING down(only had animal run at all,a 6X6 elk my wife shot-poor shot placement) With smaller calibers I have seen them get up even when knocked down, but not often, the smaller the caliber the more often it happens. Also, I pointedly did NOT say small and fast wasn't as good as big and slow. I said that one doesn't kill any better than the other just that small/fast allows em to run more before expireing. Which is almost exactly what you said.
