My belief structure concerning ballistic stopping power and predictions of same is an amalgam of TLG, Hatcher, Marshall-Sanow, Keith, Skelton, Jordan, and a number of trainers I have learned from over the years. Add in quite a bit of ER and autopsy attendance and the discussions had with the medical professionals involved in those inquiries. Eclectic, I know--not deeply disciplined, either. I do try to alloy some common sense into the mix as well. As alluded to above, even an unlettered mountain man of the 1830s knew darn well that a 24 bore (58 caliber) roundball hit better and harder than some .36 caliber rifle. Rocket science it isn't, in many ways. There are no "bad" loads in 357 Magnum for felon repellent.......the 125 grainer runs faster than the 158 grainer, might have a better expansion potential, and seems to have a bit less recoil--but both do the job well. One is better served to practice more frequently and hone one's own edge rather than try splitting hairs with it over minutae like bullet weight. Driven to the caliber's full potential--current SAAMI or 1935 Doug Wesson--all bullet weights are more than adequate to the task. There is no compensation for poor placement or non-placement.......you can't miss fast enough to win a gunfight (thanks to the late Sgt. Varga for that).
