The general equations of the six-degree of freedom problem of the lateral constraint forces on a projectile traveling in a gun bore are indicated. In general, the bore is not straight, the projectile is imbalanced, and the principal axis of inertia of the projectile is not aligned with the spin axis. Complete equations are derived for two special cases where the rifling is of constant pitch the first case being that of an imbalanced and misaligned projectile traveling in a perfectly straight bore, and the second case being that of a perfectly balanced and aligned projectile traveling in a crooked bore.
