[QUOTE="Beng, post: 1132454, member: 37512"] Suggestion: Buy the Applied Ballistics book. How stability is influenced by changes in air density and temperature are explained in there. Short: The denser the air, the greater the forces acting upon the tip of the bullet will be. Bullets swerve a little, when the tip swerves off the flight path, the center of pressure and center of gravity aren't aligned anymore in the direction of the force enacted upon the bullet by air resistance. This creates a moment trying to overturn the bullet. High altitude and high temperature both reduce air density. [/QUOTE]
