Doc GKR has stated they have observed temporary cavitation wounding with hot loaded 44 mag. So it seems like that is where it really starts. From a discussion I had somewhere about it, he said that shape and mass also play a role. My example was a tank sabot round at 1700 FPS, would that cause temporary cavitation wounds? The consensus was probably yes.
From personal experience, Ive investigated a few suicides done with magnum revolvers. The wounds were significantly more severe than with what I normally see with the service cartridges. That being said, I always believed the extra muzzle blast was the contributing factor. But who knows.

No dude is going to get shot in the chest at 300 yards and look down and say "What is that, a 3 MOA group?"
