The James projectiles
nearly always threw the lead sabot after firing, endangering friendly troops and tending
to cause an unstable flight. This led to the replacement of the James projectile
with a Hotchkiss pattern (pictured) that could be fired from the existing James rifled
cannon. The patent date is cast into the base cup. The fifteen lands and
grooves of the James rifling is evident on the lead band. Solid-shot Hotchkiss
projectiles are also found in the following field artillery calibers: 2.6
inch, 3-inch, 3.4-inch, 3.5-inch, and in 3.67-inch.
