So, the greater the velocity the greater the KE at impact (we all knew that). But the higher the twist the greater the force pulling the bullet apart for a given velocity and the larger the bullet the greater the force trying to pull the bullet apart. No idea if that rotational force is meaningful. Meaning, does it approach the structural integrity limit of the bullet where more force equals greater opening.

Back to the OPs thought though, I would like to see some form of apples to apples comparison of the various monos impacting near 1800 FPS and see how different they are.
