This is an example of the most common 10-pounder (2.9-inch caliber) Brooke
projectile recovered. It was turned on a lathe from the sabot to the ogive. Lathing was
needed to turn the projectile casting down to the dimensions needed to properly fit into
the bore of the cannon. The thin walled copper sabot tended to break as it expanded into
the grooves of the cannon. In an attempt to correct this problem the sabot was made
thicker and pre-cast with the rifling grooves, as can be seen in here. This pictured
example was recovered from the June 1864 Battlefield of Kennesaw Mountain, Georgia.
Stamped into the copper sabot is the letter "8". Also found
stamped on field caliber Brooke projectiles are the letters "G"
and "D".
