The Blüm machine gun (Russian: Пулемёт Блюма) was a Soviet training machine gun designed by Mikhail Nikolayevich Blüm around 1929. It was chambered for the .22 Long Rifle cartridge. [1] The gun was developed in order to reduce the training costs in terms of ammunition and wear of the Soviet machine guns in service at the time. [2]

Machine gun fully automatic mounted or portable firearm

A machine gun is a fully automatic mounted or portable firearm designed to fire rifle cartridges in rapid succession from an ammunition belt or magazine for the purpose of suppressive fire. Not all fully automatic firearms are machine guns. Submachine guns, rifles, assault rifles, battle rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire. As a class of military rapid-fire guns, machine guns are fully automatic weapons designed to be used as support weapons and generally used when attached to a mount- or fired from the ground on a bipod or tripod. Many machine guns also use belt feeding and open bolt operation, features not normally found on rifles.

.22 Long Rifle ammunition

The .22 Long Rifle or simply .22 LR is a long-established variety of .22 caliber rimfire ammunition, and in terms of units sold is still by far the most common ammunition in the world today. It is used in a wide range of rifles, pistols, revolvers, smoothbore shotguns, and even submachine guns.

Known production figures for this gun at the Degtyarev plant are: 33 made in 1933, 1,150 made in 1934 and 1,515 made in 1935. [1]

The large surplus of 7.62×54mmR machine guns and ammunition available in the Soviet Union after the end of World War II made the Blüm guns obsolete for training purposes. [2] After they were decommissioned from the military in the 1950s, some of Blüm guns were refitted with wooden stocks and used as varmint guns in a campaign to control wolf populations. [1] In this application they were considered superior to 12-gauge shotguns loaded with buckshot, particularly because they were employed from aircraft flying at 50–100 meters, and a salvo from the Blüm gun could kill an entire wolfpack. [2]

7.62×54mmR Russian rimmed rifle cartridge

The 7.62×54mmR is a rimmed rifle cartridge developed by the Russian Empire and introduced as a service cartridge in 1891. Originally designed for the bolt-action Mosin–Nagant rifle, it was used during the late Tsarist era and throughout the Soviet period to the present day. The cartridge remains one of the few standard-issue rimmed cartridges still in military use and has the longest service life of all military-issued cartridges in the world.

Pistolet-pulemet (Пистоле́т-пулемёт) means submachine gun in Russian. The name is most often used in relation to a series of weapons made by the Soviet Union which includes PPD-40, PPSh-41 and PPS-43. The letter after the PP (ПП) in the gun's designation is from the designer's name. For example, the "Sh" in PPSh stands for Shpagin.

Revolver cannon autocannon, commonly used as an aircraft gun, that use a cylinder with multiple chambers (like a revolver handgun) to speed up the loading-firing-ejection cycle

A revolver cannon is a type of autocannon, commonly used as an aircraft gun. It uses a cylinder with multiple chambers, like those of a revolver handgun, to speed up the loading-firing-ejection cycle. Some examples are also power-driven, to further speed the loading process. Unlike a rotary cannon, a revolver cannon has only a single barrel, thus its spun weight is lower. Automatic revolver cannon have been produced by many different manufacturers.

Degtyaryov machine gun light machine gun of Soviet origin

The Degtyaryov machine gun or DP-27 is a light machine gun firing the 7.62×54mmR cartridge that was primarily used by the Soviet Union, with service trials starting in 1927 followed by general deployment in 1928. Besides being the standard Soviet infantry light machine gun (LMG) during WWII, with various modifications it was used in aircraft as a flexible defensive weapon, and it equipped almost all Soviet tanks in WWII as either a flexible bow machine gun or a co-axial machine gun controlled by the gunner. It was improved in 1943 producing the DPM, but it was replaced in 1946 with the RP-46 which improved on the basic DP design by converting it to use belt feed. The DP machine gun was supplemented in the 1950s by the more modern RPD machine gun and entirely replaced in Soviet service by the general purpose PK machine gun in the 1960s.
