# Needle gun

A needle gun (or needle rifle for varieties with rifling) is a firearm that has a needle-like firing pin, which can pass through the paper cartridge case to strike a percussion cap at the bullet base.

## Types
### Pauly

The first experimental needle gun was designed by Jean Samuel Pauly, a Swiss gunsmith.
In 1808, in association with French gunsmith François Prélat in Paris, France, Pauly created the first fully self-contained cartridges; the cartridges incorporated a copper base with integrated mercury fulminate primer powder (the major innovation of Pauly), a round bullet and either brass or paper casing. The cartridge was loaded through the breech and fired with a needle. The needle-activated central-fire breech-loading gun became a major feature of firearms thereafter. The corresponding firearm was also developed by Pauly. Pauly made an improved version which was protected by a patent on 29 September 1812. The cartridge was further improved by the French gunsmith Casimir Lefaucheux in 1836.
In 1809, Pauly employed the German Johann Nicolaus von Dreyse, who later invented the famous Dreyse rifle.

### Dreyse

The first mass-produced needle gun was invented by the German gunsmith Johann Nicolaus von Dreyse, who, beginning in 1824, had conducted multiple experiments, and in 1836 produced the first viable breech loading gun model using a complete cartridge.
The early Dreyse needle guns were smooth-bore. Later Dreyse guns adopted by the Prussian army were rifles using self-contained combustible cartridges holding oblong lead balls held in a papier-mâché "sabot".
From 1848 onwards the new weapon was gradually introduced into Prussian service. Between 1849-1867, The British military inspector had trial an early bolt action variants. The Dreyse rifle became widely used during the Austro-Prussian War of 1866 when it played a decisive role at the Battle of Königgrätz.

### Doersch and von Baumgarten

This Model 1861 rifle was an improvement of the Dreyse rifle by Johannes Doersch and Cramer von Baumgarten. They shortened the needle mechanism and moved the handle to the rear of the bolt. The rifle was officially adopted in the Principality of Schaumburg-Lippe. More than one thousand rifles were produced until the principality was forced to join the German Empire in 1871.

### Carl

In 1865, Johannes Friedrich Christian Carl (also known as Carlé or Karl), a ship- and insurance broker of Hamburg, patented a needle gun which was an improvement on the Dreyse gun. Sohs (Zons), a Hamburg citizen, participated in the design and development of it.
The Carl system was officially adopted by the Russian Empire in 1867. Only 215,500 Carl rifles were manufactured in Russia, because a short time later, needle rifles were replaced by rifles with metal cartridges, such as the Berdan rifle.

### Chassepot

The Chassepot was named after its inventor, Antoine Alphonse Chassepot (1833–1905), who, from 1857 onwards, had constructed various experimental forms of breechloader, and the rifle became the French service weapon in 1866. In the following year it made its first appearance on the battlefield at Mentana on 3 November 1867, where it inflicted severe losses upon Giuseppe Garibaldi's troops. It was reported at the French Parliament that "Les Chassepots ont fait merveille !", or loosely translated: "The Chassepots have done wonderfully!" The heavy cylindrical lead bullets fired at high velocity by the Chassepot rifle inflicted wounds that were even worse than those of the earlier Minié rifle.
In the Franco-Prussian War (1870–71) it proved greatly superior to the German Dreyse needle gun, outranging it by 2 to 1.
The Chassepot used a paper cartridge, that many refer to as being 'combustible', whereas in reality it was quite the opposite. It held an 11-millimetre (0.43 in) round-headed cylindro-conoidal lead bullet that was wax paper patched. An inverted standard percussion cap was at the rear of the paper cartridge and hidden inside. It was fired by the Chassepot's needle (a sharply pointed firing pin) upon pressing the trigger.

### Carcano

The Carcano Fucile di Fanteria Modello 1860/67 needle gun was developed by Salvatore Carcano, an Italian technician. This rifle was operated by pulling a cocking knob on the back of the action, retracting the needle and allowing the bolt handle to be lifted. It was adopted in 1867 in Italy.
The Carcano Modello 1868 needle fire rifle had very few differences from the 1860/1867 model.
