Confederate case-shot projectile

The process used to construct this example is as follows:  After the casting was removed from the mold, the fuze and side-loader holes were finished and threaded, a dowel was inserted into the fuze hole to the opposite side, and the iron balls were inserted through the side-loader hole, followed by hot matrix.  After the matrix cooled the dowel was removed, leaving a space for the bursting charge.  Compared to canister, case-shot projectiles had a greater effective range when used as an anti-personnel weapon.
