Berdan rifle

In February 1866, General Hiram Berdan patented a trapdoor mechanism for firearms and a Berdan-type gun was submitted to the United States Army trials of 1865–6, but it was rejected in favor of the Springfield Model 1866. Berdan also developed a hammerless action, using a straight-line striker instead of an external hammer, which was patented in the United States in March 1869. In 1869, the Russian Empire ordered a total of 30,000 rifles and 7.5 million 10.6 mm cartridges from Colt, while a slightly modified Berdan trapdoor-action was adopted by Spain in 1867 to convert their old caplock rifles to use metallic cartridges. According to E. C. Ezell, Russian plans of locally manufacturing Berdan No. 1 rifles came into a halt when Berdan himself arrived in Saint Petersburg in the spring of 1869 to promote his bolt action No. 2 rifle, which was tested by the Artillery Commission and recommended by the Minister of War Dmitry Milyutin, who ordered the production of No. 1 rifles (out of an order of 60,000 rifles, only 16,575 rifles were produced by Russian arsenals) to be terminated in favor of the No. 2 rifle. After some objections from Gorlov, who believed that Berdan's new design was inferior to the No. 1 rifle, new tests with both rifles were conducted and ultimately Milyutin decided on the production of the Model 1870 Berdan (No. 2) rifle. ==Berdan I==

Two different versions of the later single-shot Berdan rifle were adopted as service weapons by Imperial Russia. The first version, manufactured by Colt in the US, is known as model 1868, or Berdan I. It is a hammerless "trapdoor" breechblock design, and was manufactured in limited numbers (the contract stipulated 30,000) as a full-length infantry rifle. Colt also manufactured a few half-stock Berdan I cavalry carbine prototypes, but these were never adopted for Russian service. Colt even produced a few target rifles based on the Berdan I. ==Berdan II==

The model 1870, or Berdan II, is a single-shot bolt-action with a distinctive short, pear-shaped bolt handle. The bolt handle serves as the only locking lug for the action, and when closed, points upwards at a 30-degree angle, rather than horizontally. The Berdan II was produced in four variants: an infantry rifle, the lighter and slightly shorter Dragoon rifle, a Cossack rifle with a button trigger and no trigger guard, and a cavalry carbine. Infantry and dragoon rifles were issued with quadrangular socket bayonets. Initial production of the Berdan II was at Birmingham Small Arms in England. The rifles were later manufactured in large numbers by Russian factories at Tula, Izhevsk, and Sestroretsk. Estimated total production of all models is over 3 million. The rifle was known for its accuracy, simplicity and reliability. ==Cartridge==

The 10.7×58mmR cartridge used in the Berdan was also invented by Hiram Berdan, with the assistance of Russian colonel . It was the subject of many patents in both the United States and United Kingdom. The bottleneck cartridge case used the Berdan primer, its first use in a small arms cartridge. Cartridges were issued in blue paper packets of six rounds each. In addition to the regular cartridge for rifles, a special cartridge was manufactured for use in the cavalry carbine. It consisted of the same cartridge case and bullet, but with a lighter powder charge of only 4.5 grams, and was issued in six round pink paper packets. At the time of its use, the 10.75×58mmR (4.2 line) cartridge was known for its power and accuracy. ==Later usage==

No magazine-fed versions of the Berdan ever progressed beyond the prototype phase. Russian troops, however, did have various cartridge holders, such as the Krnka quick-loader, attached to their rifles to aid in reloading. By the late 1880s Russia began the process of replacing the Berdan with a high velocity and magazine fed rifle, and this resulted in the adoption of the Mosin–Nagant. In 1892, a batch of 3,004 Berdan II rifles were converted to 7.62×54mmR for Russian service by arms makers in Belgium. These rifles have new barrels and sights, and new bolts with a front locking lug and longer bolt handle. Had the conversion been deemed fit for service, an additional 40,000 were to be converted. However this did not go through. Sporting rifles and shotguns were re-manufactured in Russia from surplus rifles after the Mosin–Nagant was adopted into service, often referred to as "Frovlovka" ==Markings==

Markings on the Berdan rifle usually consist of the Imperial Russian double-headed eagle cypher on the top receiver flat. The manufacturer's name in Cyrillic, date of manufacture, and rifle serial number, are on the top of the barrel. Some rifles also show a date of manufacture on the receiver. The serial number was also applied to the bolt. Additional proof marks and property markings are found on the receiver and barrel. There is a factory cartouche on the right side of the buttstock. == Comparison with contemporary rifles ==

• : Acquired a small batch of Berdan №1 rifles in 1877 and were in service until 1881. • : Captured rifles were used in WW1. The receivers were marked "AZF" by Artilleriezeugsfabrik & had sling slots added to the stock. Some were converted to flare guns as well. • :1000 supplied to Muzaffar bin Nasrullah by Russia in 1883; those weapons were only issued after 1885. 2000 purchased for 'Abd al-Ahad Khan's bodyguard in 1889 • Kingdom of Bulgaria: At least 30,000 Berdan №2 rifles and 10 million rounds were bought from Russia for the Bulgarian army. They were replaced in front line service with Mannlicher rifles. • : The Russian Empire sent 30,000 Berdan rifles to Ethiopia before the First Italo-Ethiopian War. Some were hand-modified into carbines • : Limited usage during the Winter War • : During the Franco-Prussian War, France purchased 5,760 Berdan №1 rifles & 63,000 Spanish M1857/67 models. • : Limited use of captured rifles during WWI • : A Cossack unit was formed and provided Berdans from the Czar. • :Smoothbore copies manufactured in the 1870s. • : At least 3,000 rifles were received from Russia • : Received 30,000 Berdan №2 and 15 million cartridges in 1895. • Russian Empire: Both the Berdan №1 and Berdan №2 were used by guard units in the Russian Army during the Russo-Turkish War of 1877–78. Russian forces, although ultimately victorious, were badly mauled by the very long range fire from Turk Peabody–Martini rifles during the Siege of Plevna. After the war a long-range auxiliary sight was adopted and retrofitted to the Berdan II infantry rifle. The Berdanka, as it was called, continued on in Russian service even after the adoption of the Mosin–Nagant, primarily with reserve and rear echelon units when the Mosin-Nagant became plentiful. Many Russian troops had Berdan rifles in the Russo-Japanese War of 1905. During World War I, some Russian second line, training and service units were armed with the Berdan II. It is common to see Berdan rifles in photos of street fighting taken during the Russian Revolution of 1917. • Kingdom of Serbia in 1890 received 76,000 rifles as military aid. They saw service in the Balkan Wars and the First World War in the hands of Serbian soldiers of the 3rd class (men over 50 years old). • : Berdan-trapdoor conversions • Yettishar:1000 supplied by Russia in 1869. Locally made copies were manufactured. ==See also==
