I found this interesting. Being a science guy I always get into this type of stuff and enjoy ballistics gel tests for the reasons that are explained in this video. The thing I found interesting was the 2200 fps threshold they spoke of. I can't remember if I have read about this before or not, but their explanation was good. I would say this is worth the watch. Yes it is mostly about handgun performance, but there are tidbits that relate to us long range guys like perhaps this 2200 fps bit. Obviously velocity really comes into play when talking hydrostatic shock. And there is a point where that velocity is insufficient. I am sure sure shape and surface area play a role as well, but like I said, interesting and imo worth a watch. I'll leave it here and you guys can discuss, add, or detract.
