Can a bullet be over stabilized?
Over stabilization in bullets occurs when the barrel’s rate of spin exceeds the bullet’s aerodynamic need. In the most extreme cases, a very light bullet, driven to very high velocity, at an excessive rate of twist, will explode upon exit of the rifle barrel. That’s the extreme.
