In any case, such an item should never be places into the muzzle of a loaded musket. A discharge with this obstruction could result in a split barrel. One other item that is worth mentioning is the wooden or practice flint. For drill purposes, the regular flint is removed from the musket jaws, and the wooden flint is substituted. It is important fir the drill instructor to hear the click of the musket firing to determine if the squad is firing in unison.
Wooden flints are simply small squares of hardwood, approximately the same size as a musket flint.
They are easily made from scrap wood, and were probably made up as needed in the field from boxes and barrels used for shipping. The handling and firing of a flintlock musket creates several dangerous conditions. Accidental discharges can occur if the flint accidentally falls, striking the steel and throws sparks into the pan causing the musket to fire. This can happen in several ways, such as a worn half-cock notch in the tumbler of the lock allowing the flint to fall when jarred. A somewhat anachronistic solution to this problem has been the development of the hammer stall.
