Bryan Litz, in Applied Ballistics for Long Range Capturing, pointed out that greater velocity may well incorporate towards the RPM for better steadiness, but that also boosts force applied to the nose with the bullet as it spins and increases aerodynamic torque (which means less security). The 2 opposing forces mainly cancel one another out.
