# Yawing motion of a M193 bullet cal. 5.56 x 45

Imagine that the bullet´s CG moves on a straight line in the middle of the box,. Then the spiral-like curve indicates the spatial movement of the bullet´s tip along the range in calibres (0...8000 calibers). In this example, the M193 bullet shows a small precession instability.
