Typical revolvers paper cartridges differ from heavy-duty percussion rifle cartridges in that the cartridge is inserted into the chamber as a whole and rammed. Turret cartridges were often flammable, and the bullet is usually exposed, with the paper cartridge glued, usually with sodium silicate, a high-temperature glue that was widely used because it was also used to keep eggs fresh. Many specimens were tapered to a cone and wider at the ball than at the back. Some commercially manufactured cartridges, such as those from Hayes in England, were also equipped with a small cloth tear on the front to help remove the protective outer layer before loading the cartridge. [3] [8] The paper used in the cartridges varied considerably. Published in 1859, the Enfield Paper Cartridge Manufacturing Manual, which uses three sheets of paper of two different thicknesses, shows the complexity this could entail. Some cartridges, such as those for percussion revolvers, used nitruated paper. Treated by soaking in a solution of potassium nitrate and then drying, this made the paper much more flammable and ensured that it was completely burned when burned. [8] With the advent of the rifle musket and the widespread introduction of rifled barrels by the armed forces, the spherical projectile eventually went out – although the new elongated bullets were still called bullets in the army (in fact, full metal casing ammunition is still called bullet ammunition today). While conical bullets and bullets were used with rifles for several hundred years, both in cartridge form and loose form, the Minié bullet contained the mid-19th century. In the nineteenth century, a number of important innovations made it possible to take over the rifled weapons of the main infantry units, rather than being reserved for elite units of tirailleurs and riflemen. The design of the paper cartridges varied depending on the buyer`s specifications or the manufacturer`s practices; A cartridge was usually built with a specific weapon in mind, with a specific charge of powder and a bullet or bullet of appropriate size.
A cartridge built for a .65 caliber musket obviously could not be used in a .50 caliber weapon. However, weapons of similar size could often share cartridges. During the American Civil War, the main handguns used by both sides were the .58 caliber Springfield Model 1861 musket (North) and the .577 caliber Enfield rifle musket (South). The two guns were similar enough that both sides could easily fall back on ammunition captured by the enemy. Mini-munitions with loose bullets in rifled muskets meant that slightly undersized ammunition could be used in an emergency, although accuracy was compromised compared to properly sized ammunition. The end of the cartridge bullet was crimped and the end of the powder was filled and folded closed. The bullet tip of the finished cartridge was then dipped in a mixture of melted beeswax and tallow to lubricate the bullet. [1] A paper cartridge is one of many types of small arms ammunition that were used before the advent of the metal cartridge. These cartridges consisted of a paper cylinder or cone containing the bullet, gunpowder and, in some cases, a primer or lubricant and an antifouling agent.
Combustible cartridges are paper cartridges that use paper treated with oxidizing agents to allow them to burn completely when ignited. [1] [2] [3] The revolver paper cartridge lasted longer than usual and encompassed a wider range of shapes, as Rollin White covered the patent pierced by cylinders on a turret (used for a paper cartridge application). This patent was granted under exclusive license by Smith & Wesson, giving them an effective monopoly on the American production of efficient cartridge revolvers until the patent expired. Since they could not convert to rimfire or centerfire cartridges, other manufacturers had to stick to percussion systems or develop proprietary front-loading cartridges. [3] [10] “Cartridge paper”.

Smoothbore muskets were loaded with lead balls slightly smaller than the bore diameter to facilitate ramming of the gun (especially when fouling accumulated); A “patch” of paper or cloth was wrapped around the bullet before inserting it into the barrel so that it fit snugly so that it does not recoil when the muzzle is tilted downwards. It also helped that the bullet didn`t bounce off the run when it was fired (see Wind). A typical flintlock cartridge consisted of a tube of paper attached together in three places to form two compartments. The first compartment contained the projectile(s), either a single round bullet or a large round bullet plus three shotgun bullets in the case of a goat and bullet charge.
The second compartment contained the powder charge. To load the musket, the following steps were used:[7][9] The paper, usually of thick and sturdy quality, keeps the undersized ball centered in the bore. As each shot leaves more and more dirt in the barrel through the gunpowder, this makes each shot more and more difficult to load. This can be supported by the use of a lubricant, which not only serves to slide the ball into the barrel, but also serves to mitigate contamination of the bore so that it is pressed freely when loading. [1] [7] To load the rifle, the end of the powder was opened by unfolding or tearing and the powder was poured into the barrel. The end of the ball was then inserted up to the height of the thick paper tube, which was then torn off and discarded. The ball was then seated with the rod and nipple primed with a percussion cap. Despite the complexity of their construction, paper cartridges were used in the 19th century, from the Napoleonic Wars to the time of the American Civil War, after which they were replaced by modern metal cartridges and the magazine by the breech. Paper shot cartridges, consisting of a paper body with a brass base and edge, were manufactured and used for many years after their general replacement by plastic cartridges. However, the only areas where they are still used in fairly large numbers are in extremely cold areas, where plastic shells often crack when fired at temperatures of -40 degrees C (-40 °F) and when loading projectiles at very low pressure for extremely old shotguns. Paper shot cartridges consist of a rolled up paper tube placed in a brass base, with the mesh of the case made of compressed pulp. These cartridges are sturdy enough to be refilled several times.
[4] [14] There are a number of characteristics that are not specific to a particular firearm and therefore apply to any paper cartridge. For example, the cartridge must be robust enough to withstand the handling that can be expected. This means that a sturdy paper should be used or the cartridge should be reinforced for strength. The importance of paper cartridges is evidenced by the existence of cartridge paper, a paper manufactured specifically for the production of paper cartridges. In some cases, the cartridges were made directly from pulp and formed into a seamless cylinder with the correct diameter. [1] [6] As the projectile`s velocity increased with better and more consistent gunpowder, loading, and firing techniques, a well-fitting lead projectile was found to leave lead trails, contributing to the contamination of the borehole. Lubrication helped somewhat, but even that had problems picking up gravel and other hard debris that damaged the bore of the firearm. The solution was to wrap the contact surface of the projectile with paper, placing a lubricated calf or waxed cotton disc behind the projectile. With a grooved projectile, lubrication is readily available, often eliminating the need for additional lubricated cotton behind the projectile.
When a barrel is fired, the projectile must activate the rifle to give rotation, greatly improving accuracy. The Minié sphere made it easy to load a slightly undersized base projectile that expanded for sealing; Or a loose round bullet would use the cartridge paper as watting and sealant. Accuracy has increased from 50 to 100 yards for a smooth bore to about 400 to 600 yards with repeatable accuracy for trailed runs. At the longest distances, a striped run could reach 2000 to 2500 yards. Although it lacked accuracy, it became possible to fire effectively at an enemy from a distance, with units of disciplined shooters taking turns firing at a common target. The concept of a fully autonomous paper cartridge for cylinder head loader was patented in 1808, just one year after the invention of the impact cap. One of the first widely used breech-loading firearms was the Dreyse needle pistol, patented in 1839 and used by the Prussian army. The needle gun used a uniform cartridge that contained a bullet, powder and primer in a paper package.
The primer was at the base of the bullet, and the fire pin or needle penetrated the back of the case, passing through the powder and hitting the primer to ignite it. [2] [4] [11] Paper cartridges were often coated with beeswax, lard or tallow, which served several purposes. They offered a certain level of water resistance, they lubricated the bullet wrapped in paper when pressed into the borehole, they melted when pulled to mix with the powder residue, and they more easily removed the resulting pollution, and they were not as dangerous to transport and handle (especially in combat) because the gunpowder inside was not as susceptible to ignition by wandering sparks or other sources of ignition.
