Abstract: A method of manufacturing a premeasured compressed charge in which the compressed charge has a leading end portion with a smaller dimension than both a trailing end portion and a desired caliber of the intended firearm and the trailing end portion has a larger diagonal dimension than the desired caliber of the firearm. The method comprises the steps of providing a mold with cavities, filling the mold cavities with gunpowder, pressing gunpowder to form a compressed charge so that one of a density and a compaction of the gunpowder, adjacent the leading end portion of the compressed charge, is about 0% to about 5% less than the density or the compaction of the gunpowder adjacent the trailing end portion to facilitate a more complete combustion of the compressed charge upon discharge of the firearm, and removing the compressed charge from the cavities.

Abstract: A clean burning premeasured compressed charge for use in black powder firearms as well as cartridges. The premeasured compressed charge is manufactured to have a substantially desired shape which facilitates improved flame propagation by the leading end wall and along the exposed sidewall surfaces of the compressed charge to result in a more complete and rapid burning of the compressed charge both from the leading end wall toward the trailing end wall and also radially inwardly from each one of the four sidewalls toward a center of the premeasured compressed charge. The premeasured compressed charge has a leading end portion and a trailing end portion and the leading end portion is either the same size or a smaller dimension than the trailing end portion.

Abstract: A consumable premeasured charge for use with an intended black powder firearm having barrel with a desired caliber, the consumable premeasured charge comprising a closed container defining an interior chamber and loose granular gunpowder filling a volume of the interior chamber to between 50 and approximately 100%. The closed container being sized to be loaded within a gun barrel of the intended firearm. A method of forming consumable premeasured charge is also disclosed.
