sorry if this seems like a dumb question, and i'm sure the answer is probably going to be something obvious, but it's been bugging me.
according to fackler's wound ballistics theroy, temporary cavitation doesn't matter, and the important factors are sufficient penetration to reach vitals + permanent crush cavity.
so, if temporary cavity is not important, what is fackler's reasoning for why .308 FMJ does more damage than .45acp FMJ? both rounds have enough penetration to go right through the average person - and .45 acp will have a larger permanent crush cavity volume due to it's larger diameter. I realize that .308 will probably yaw at some point, but yawing is fairly brief and doesn't crush that large of a volume of flesh. so what's the deal here? i can't help but think that temporary cavitation is a more important wounding mechanism than fackler is letting on, but i'm sure he has an explanation for this - i just can't find it.
