I've done enough hunting to be convinced that there is no such thing as sure "knock down" power.

I once shot a zebra with a .30/06 - he went down right in his tracks . . . and I mean STRAIGHT down, right on his belly, like someone had dropped a Buick on him. And zebra's have a reputation for being difficult to put down.

I also shot a bushbuck (think of a small Texas whitetail) with a .375 H&H, breaking the shoulder and taking out the heart . . . and he still ran about 50 yards on three legs. Tough little so-and-so.

Most people probably aren't as tough as wild animals, but the odds are you're not using a rifle, either. So in a defensive situation - keep shooting until the threat is ended. Shoot as fast as you can get hits - don't fire a shot and wait for a reaction. And use the biggest practical cartridge you can.
