What larger, more powerful rounds give is a more likelihood of immediate incapacitation.
If and only if they land in the same place.
And about the FBI report. It has been much misinterpreted.
True.
They gave a list of criteria. #1 was adequate penetration. Note the word 'adequate'. Once one gets past the adequate part then OTHER factors come into play. First among them is DIAMETER.
Forget the " list". What they concluded was that the most important factor is what is actually
hit. Penetration enters into that, as does placement. And so does diameter, to much a lesser extent.
So, what do we mean by "placement"? We mean what the bullet hits
within the three dimensional body of the assailant. No , it is about not how the shooter aligns the sights and pulls the trigger.
No one can reasonably visualize where those jostling and hidden key target are within a moving, turning and twisting assailant moving at, say, five meters per second, and shoot at them. Hitting---
placement, in this context--is a
stochastic process. It's a matter of chance.
More shots fired faster will
greatly increase the probability of "well placed" hits and therefore that of an effective stop, all other things being equal.
Larger diameter projectiles (expanded) will also help,
all other things being equal, but it doesn't take much of a mathematician to show that the effect will be small indeed.
What it will then boil down to is how fast one can fire how many controlled shots with what gun. Probably the biggest factor in that is recoil.
