Thread: Twist rate vs velocity vs bc

So for any given bullet in theory for the same pressure more velocity should be obtained by a slower twist using less energy and friction to rotate the bullet, what are your experiences with this?

An over stabilised bullet may not tip and follow its arc of travel but stay spinning on the axis of the bore at long range increasing drag as it falls threw the air, anyone observed this?

How does the stability factor affect the way the bullet transitions the sound barrier at ELR or is this more a function of the form of the bullet?
