Watched this when it came out. Mostly valid, I think, but I cannot help believing that the stopping power edge still goes to .40 and over vs .355/9mm. Not by much, but possibly, on occasion, when it counts most. I think, for example, that a 230 grain Gold Dot from a .45 will be more likely to produce a quick stop in a determined attacker than a 124 grain Gold Dot 9mm, all other factors (e.g., barrel length) being equal.
If one is observant and shoots enough game, it becomes obvious that larger calibers are higher on the food chain, especially as size of the game increases
A proper bullet and shot placement matter most
