boatanchor, I am sure that an under stabilized projectile can become stable down range, and physics explains this.
I am also sure that the better grouping my fellow posters are describing is also real.
My point is that if the groups are tightening up, after dispersing due to this yaw, physics demands a better explanation.


Democracy is not freedom. Democracy is two wolves and a lamb voting on what to eat for lunch. Freedom comes from the recognition of certain rights which may not be taken, not even by a 99% vote.
