Design paper cartridge and iron ramrod

The introduction of the paper cartridge increased rate of musket fire significantly. Before this invention, shooters had to fill the barrel with gunpowder from a tube, then flatten and cork it with a wad and put a bullet into the barrel. All these operations took up too much time and the rate of fire was low. Once the paper cartridge had been introduced, a marksman had only to put a ready-made cartridge into the barrel, which made the reload time much shorter.
