# How does a bullet achieve its stability when fired?

As far as I know, darts, arrows, and airplanes have the center of gravity(CG) ahead of their center of pressure(CP) and often have fins at the rear to achieve stability. Contrary to these, bullets have CP ahead of CG and they do not have fins. Thus, how do bullets acquire stability?

• Just guessing here: rockets are pushed from behind to accelerate, while bullets are pushed from the front to decelerate....so it all makes sense? – JEB Jul 29 '20 at 14:36

• can a spherical projectile of the pre-rifle days even be unstable? I mean if $I_{ij} \propto \delta_{ij}$.... – JEB Jul 29 '20 at 14:38
