This article addresses older paper small-arms cartridges, for modern metallic small arms cartridges see Cartridge (firearms).
A paper cartridge is one of various types of small arms ammunition used before the advent of the metallic cartridge. These cartridges consisted of a paper cylinder or cone containing the bullet, gunpowder, and, in some cases, a primer or a lubricating and anti-fouling agent. Combustible cartridges are paper cartridges that use paper treated with oxidizers to allow them to burn completely upon ignition.
Paper cartridges have been in use for nearly as long as hand-held firearms, with a number of sources dating their use back to the late 14th century. Historians note their use by soldiers of Christian I in 1586, while the Dresden museum has evidence dating their use to 1591, and Capo Bianco writes in 1597 that paper cartridges had long been in use by Neapolitan soldiers. Their use became widespread by the 17th century. The first army to officially use paper cartridges is presumed to be "piechota wybraniecka" of Poland under the rule of Stephen Batory.
Paper cartridges were often coated in beeswax, lard, or tallow, which served a number of purposes. It provided some degree of water resistance, it lubricated the paper-wrapped bullet as it was pushed down the bore, and it melted upon firing to mix with the powder residue and make the resulting fouling easier to remove. Since the standard procedure for loading a musket or rifled musket involved biting open the cartridge, this caused problems for those with strict dietary restrictions. The grease used on these cartridges was rumoured to include tallow derived from beef, which would be offensive to Hindus, and pork, which would be offensive to Muslims. The Sepoy soldiers in the employ of the British in India, for example, were largely Hindu, who were forbidden to eat beef, or Muslim, who were forbidden to eat pork. Rumors of the use of lard and tallow in the lubrication of the cartridges they were using were part of the cause of the Indian Rebellion of 1857.
