Theoretically and in a vacuum, only.

SD is a measure of potential, only. Potential being realized is always dependent on other factors, not the potential itself. That’s the Achilles of trying to declare one aspect of what a bullet does, as more important than others. Whichever one expands less in the medium it hit, and sheds energy slower will penetrate the most.....no matter what the SD started out at. I have plenty of lower SD bullets that’ll out penetrate higher SD bullets on game.....purely because of construction and retained energy/velocity. Nobody is saying SD isn’t cool and can’t indicate certain things.....just like BC, weight, expansion, velocity, etc don’t work alone, either. Ifs and buts, candy and nuts.....the ONLY time SD is anywhere near a given as ‘better’, is IF ALL OTHER factors are equal. They rarely ever are.
