I think what looks like knockdown power is nerve shock caused by a bullet. We took a fresh road kill and hung it by the neck so it was suspended by a rope. We shot this deer body with a wide variety of bullets from a wide variety of calibers. Little difference we could detect. The body merely quivered when shot with little difference we could detect. So I concluded that what is referred to as knock down power is actually shock that causes the deer legs to buckle. Sometimes they jump back up and run off and sometimes never regain their stand up position before death. I have hit the spine with a crossbow bolt and from the deers reaction one would think there was great knockdown power when we know better. Discussion is welcome, I don't mind one bit with others having a different viewpoint or experience. Ben

Good topic,, this year I watched my uncle double lung high a nice 8 point, the deer was standing relaxed broad sided, deer humped it's back slightly on impact as blood flew out the other side like a water hose on mist setting, then the deer set down on it's rear and fell over, DRT, one rib hit going in, 150 grain .30 cal bullet going really fast out of a .308, I was watching the deer through my scope all the time, field dressing there was no damage to the spine and the heart was untouched, no damage behind the diaphram either but the lungs were mush.
I've sohot deer where the heart was ripped in 2 and a lung was jelled and they still made it 50 yards,

Off topic but I also shot a large rather fat Grizzly in the butt with a rubber slug one day from 20 yards,,, you could see the shock waves run through the fat all the way up to his shoulders,,,
