Paper Cartridge - Advantages of Paper Cartridges

Advantages of Paper Cartridges

The most common applications of paper cartridges were in muzzleloading firearms. While these may be loaded with loose powder and balls or bullets, a paper cartridge combines a pre-measured amount of powder with the ball in a sealed unit. This eliminated the operation of measuring the powder during loading. In the case where multiple projectiles were used, such as buck and ball loads, the cartridge also served to package up the projectiles, so they did not have to be measured or counted out. The paper also served as a patch in smoothbore firearms, which fired undersized balls sealed in the barrel by a paper or cloth patch.

The paper used in cartridges varied considerably. The instructions for making Enfield paper cartridges, published in 1859, which uses three pieces of paper of two different thicknesses, shows the complexity that could be involved. Some cartridges, such as those for percussion revolvers, used nitrated paper. Treated by soaking in a potassium nitrate solution and then drying, this made the paper far more flammable and ensured it burned completely upon firing.

Despite the complexity involved in their construction, paper cartridges were used through the time of the American Civil War, after which time they were displaced by modern metallic cartridges.
