Not to go on too big of a tangent here (as I honestly don't know), but if bullets don't become destabilized as they slow down to a certain point both in velocity and (more importantly) RPM, but still stay transonic, why do twist rates matter? Shouldn't a slow twist barrel stabilize a given bullet the same as a fast twist barrel, as long as the bullet is transonic since RPM slows down as the bullet slows down too right? I was thinking that when a bullet's RPM slowed down at some point it would start to destabilize and wobble, regardless if it was still transonic or not.

I hate to bring so much gun gak into the conversation, but am genuinely curious.
