Abstract
In this paper, it is shown that the Magnus effect cannot be a primary mechanism for the dispersion of shotgun pellets. The one-dimensional motion of objects through air, applied to shotgun pellets traveling a short distance, reveals that throughout the flight, the Reynold’s number is approximately constant. The distribution of pellets upon the target is demonstrated to be a phased-shifted Maxwellian distribution in lateral displacement space. The minimum Magnus frequencies required to create a typical pellet distribution pattern are ascertained, and are well in excess of the frequencies that could reasonably be achieved by pellets exiting a smooth bore shotgun.

Keywords
