This pictured specimen is an example of the James Pattern I, Sub-pattern II projectile. This sub-pattern is commonly called a tie-ring James due to the visible ring extending below the base of the projectile body. The visible small notches, located in the raised portion of the projectile's ribbed body, were developed in an attempt to improve the chances of the lead sabot remaining attached to the projectile body during firing.  To learn more about the inventor, Charles T.
