John:
A friends brother used to load 90 gr HP's in a 264 Win Mag.drive them at max just for the purpose of letting us watch them disappear in a blue haze before they made it to the 100 yard target.
The rifling scored the thin jackets and all those rpm's just did the rest.Fun to watch.
I also understand that the target Bergers have tougher jackets than the hunting versions so they will withstand the high rotational forces of fast twists on rifles for LR shooting. Seems some versions would not make it to the target.
I think the same thing can happen to one extent or another (depending on the bullets construction) when an expanding bullet's jacket is compromised on impact with an animal.
