And in regard to the strict example I've stuck to (because this is a thread about the 270 and 308), you're guessing, I'm not.


It isn't quite that simple and I'm not guessing at all. Can you answer the question about the .22 bullets or not?


Your comparison is not relevant due to the drastic difference in muzzle velocity. Higher SD bullets will out penetrate lower SD bullets of the same construction at the same velocity. I don't think this is really a disputable statement. That said, it would be a very rare occasion when there would be any real terminal performance advantage shooting 150 gr .270 instead of a 150 gr .308 of like construction on game.
