Note the tin covering on the lead sabot which was an attempt to help prevent the
leading of the cannon bore during firing, which caused excessive wear and tear on the
cannon's rifling. The two-piece James percussion fuze often failed to explode the
projectile, and when the fuze worked properly, the small ineffective bursting cavity often
led to unsatisfactory fragmentation. The seam where the tin covering joined together is
clearly visible. Note the impression of the canvas on the tin sides of the projectile's
sabot. Click here for a cross-sectional view.
