Correctly understanding how their fired bullets actually fly through the air can be advantageous for serious riflemen, especially those competing in Extreme Long-Range (ELR) matches. The obsolete idea that a rifle bullet flies through the air with its center of gravity (CG) nailed to a smooth trajectory while its nose spirals around pointing outward is simply incorrect. Any 6-degree-of-freedom (6-DoF) flight simulation shows that this cannot be the case. The CG of the bullet rotates about its mean trajectory 180 degrees out of phase with the gyroscopic precession of its spin-axis direction.
