The Effects of Deformed Shot on Shotgun Pellet Dispersion
It has been previously proposed that the outliers of shotgun dispersion pattern are due to shot which are aerodynamically less stable as a result of impulse deformation at the instant of discharge. This has been confirmed by an experiment in which all of the shot are intentionally deformed before the loading of the shotshell. Any pattern of dispersed shot is therefore likely to be in part a result of a shot packing factor which describes the propensity of shot to be deformed upon discharge or to be cushioned against such deformation.
