Machine Guns in the War of 1812-- Part 6: The Bullets

With these big orders, Joseph Chambers subcontracted with John Joseph Henry and George Tryon for 20 swivels and 200 muskets to be delivered within three months.  In a design change, the swivels were to have seven instead of eight barrels.

The special lead shot used in all these weapons consisted of a  cylinder whose thickness was one-half of its diameter.  On the projectile's bottom was a "stem," whose dimensions were roughly one-half of the upper portion.  A small hole along the central axis was the means whereby gasses from the discharge of the preceding powder charge were transmitted to the next charge, thereby continuing the firing of the weapon.
