One myth related to BC and stability warns of the consequences of over-stabilizing bullets with too fast of a twist. The myth states that: spinning a bullet too fast can cause excessive stability and prevent the bullet from tracking with the trajectory, so it falls ‘nose-high’ on the downrange end, and causes more drag. This myth is easily dispelled if you recall the definition of stability, which is that the projectile aligns with the oncoming air flow. It does this even as the trajectory bends, and even for high SG’s obtained with fast twist. In fact, doppler radar data consistently shows that faster twist and higher SG’s actually reduce drag, especially at transonic speed for bullets fired at long range. The myth warning of overstability stems from high angle artillery fire where rounds could sometimes fail to track, and fall base first to the ground. This is not a problem in the realm of small arms rifle bullets shooting at small angles (under 30 degrees).
