Perhaps the most useful post in the thread.

Far more effort is often expended trying to find the "magic bullet" than in practicing with the firearm in question. That's always the advice given by any legitimate expert in the field of wound ballistics. Shot placement will always trump bullet selection.

Having said that, there are ways of determining which projectiles meet minimum standards. There is still ammunition being sold today, billed as "superior performance", that exhibits characteristics 180 degrees different than what is universally accepted as ideal by the majority of wound ballistics experts. Those rounds are often touted in gun magazines as having the best "stopping power", by famous gunwriters with little qualifications, and often financial ties to the companies they write about, (along with advertising dollars directed towards those magazines), or in a long ago discredited book.
