One would think that the higher spin rate would introduce more aerodynamic turbulence and rotational drag, but if so, it seems it must be more than overcome by the alignment effects. I wonder if this phenomenon is measured directly – for example, by doppler radar – or inferentially – for example by drift, or group size, both of which could be compromised if the bullet path were not linear, but rather “corkscrew” in trajectory. At what point, I wonder, would increasing spin introduce secondary destabilizing effects from bullet imperfections, like voids/density variation that would introduce eccentricity in flight (spinning about the mass centerline/”center of gravity” instead of the geometric/bore axis centerline)?
