The aerodynamic properties of a 105 mm model of the 155 mm T-358 shell are discussed. Subsonically, at small yaw, the model has a serious case of dynamic instability as indicated by a rapid divergence of the precessional component of yaw. It is shown that this instability is due to Magnus effects, and that these effects cannot be circumvented by firing at a different spin. However, because of past experience with similar shell, it is conjectured that this dynamic instability is a small yaw phenomenon and that a limit cycle is present. As a consequence of this, the dispersion will not be markedly affected.
