Stability measure?

We all (hopefully) know that kinetic energy increases linearly with mass, exponentially with velocity. KE = (1/2)mv^2

But with velocity comes instability, particularly past the supersonic velocity mark.

Granted stability has MANY other factors involved - the seating of the pellet, any deformities, tumbling during flight.

But there has to be some sort of measure to describe a pellet’s average stability by velocity and distance.

Right?
