Yes but the point was that if you started a bullet at 1100 ft/sec and it was
stable it would remain stable for it's practial range depending on its weight.
And the heavy'er the bullet the longer it would retain it's velocity (Just like the
300gr SMK compaired to a 150gr SMK shot at the same velocity).
My understanding was that the projectile would lose it's stability while passing
through the transonic speed,and can't regain accuracy once through .
The reason the new tank rounds are fired out of a smooth bore and the projectile
has stablizing fins is to avoid this problem, and eliminating the yaw that occurs
when passing through the sound barrer with a rifled barrel and a rotating projectile.
So once the bullets path is disrupted it cant find its way back on track. Hence the
accuracy problem beyond the transition.
