I actually only favor a bonded bullet in a light & fast handgun calibers, like 357sig, or most rifle rounds. In slower rounds & bonded bullet doesn't give me anything but less expansion & more penetration. I seriously doubt my fight will be thru a windshield. If it does I will fire more rounds. BTW, no one is saying ME doesn't matter, which is often quoted. No it just isn't the fight stopper. Temp cavs are just that temporary. They have only a minimal wounding ability & that is totally dependent no target size, ie 100# target v 400# target. No lightning bolt affect, as has often been thrown out. Yes ME matters, to get the expanding bullet to work, just not as much as some fantasize about. You want a fight to stop, man or beast, destroy vitals.
