I once calculate the RPM of various bullets, based on muzzle velocity and rifling pitch. Most rifle bullets exceeded 100,000 RPM, while most handgun bullets were in the 35,000 RPM. Thus, the shorter the bullet for caliber, the slower the spin, while longer bullets require faster spin rates.
The terms "understabilization" and "overstablization" while apparently non-existant, are actual terms used in ballistics. If the spin is too slow, a bullet will tumble in flight, hence lose any aspect of accuracy. A bullet that is "overstablized" or spun too fast, will not follow the trajectory's arc, but will tend to remain constant with the angle of departure. Such overstalization results in loss of downrange performance as well as a loss of accuracy.
An overstabilized bullet will display key holing downrange on a paper target.
Granted, these are very long range studies conducted for overhead machine gun fire and heavy artillery, but the application is the same. Regardless of the caliber, .30" or 3", projectiles having the ballistic coefficient of 1.0 behave in the same way.
