Yes, the meat analog he uses, though not perfect, is the closest to a real-world test I’ve found that a regular person could reasonably perform themselves.

357 out of a revolver is indeed still too slow, even with lighter bullets. Only in a lever action carbine does 357 start to reach the required power to perform some hydrostatic tearing, since 357 is really able to take advantage of that extra barrel length to increase velocity fairly dramatically.

There was an extremely comprehensive video done on real-world wound ballistics that I was struggling to find for my last comment, but I found it just now, once again thanks to Luckygunner.

He gives a summary of it here, and also made this video as a supplement, but if you’d like to see the absolute last word on firearm wound ballistics, I’d suggest this full documentary featuring Dr. Martin Fackler (but be warned, this has NSFW gory images as examples).
