7.62×25mm Tokarev
The 7.62×25mm Tokarev cartridge (designated as the 7.62 × 25 Tokarev by the C.I.P.) is a Russian rimless bottlenecked pistol cartridge widely used in former Soviet states and in China, among other countries. The cartridge has since been replaced in most capacities by the 9×18mm Makarov in Russian service. History Prior to the First World War, the 7.63×25mm Mauser C96 pistol gained in popularity worldwide. In 1908, the Tsarist army placed the C96 on a list of approved sidearms that officers could purchase at their own expense in lieu of carrying the Nagant M1895 revolver. Between 1914 and 1917, more Mauser pistols and ammunition were obtained as captured arms from German and Turkish forces. The Mauser and its cartridge were used on all fronts of the Russian Civil War and in the 1920s, during a period of relatively close cooperation between Soviet Russia and the Weimar Republic, the Red Army purchased batches of the smaller Bolo version as well as ammunition for use by its of ...

Full Metal Jacket Bullet
A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. A bullet jacket usually allows higher muzzle velocities than bare lead without depositing significant amounts of metal in the bore. It also prevents damage to bores from hard steel or armor-piercing core materials. History The bullet was invented in 1882 by Swiss Colonel Eduard Rubin while he was working for the Swiss Federal Ammunition Factory and Research Center, which developed ammunition for the Swiss military. The use of full metal jacketing in military ammunition came about in part because of the need for improved feeding characteristics in small arms that used internal mechanical manipulation of the cartridge in order to chamber rounds as opposed to externally hand-reloading single-shot firearms. The harder metal used in bullet jackets was less pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proof (firearms)
A proof test is a form of stress test to demonstrate the fitness of a load-bearing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above that expected in actual use, demonstrating safety and design margin. Proof testing is nominally a nondestructive test, particularly if both design margins and test levels are well-chosen. However, unit failures are by definition considered to have been destroyed for their originally-intended use and load levels. Proof tests may be performed before a new design or unit is allowed to enter service, or perform additional uses, or to verify that an existing unit is still functional as intended.Test intervals for in-service ...

Suppressor
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that reduces the acoustic intensity Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m2 ... of the muzzle report (sound of a gunshot) and muzzle rise when a gun (firearm or air gun) is discharged, by modulating the speed and pressure of the propellant gas from the muzzle and hence suppressing the muzzle blast. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle, or an integral part of the gun barrel, barrel. A typical silencer is a metallic (usually stainless steel or titanium) cylinder containing internal sound baffles, with a hollow bore to allow the projectile (bullet) to exit normally. During firing, the bullet flies through the bore with litt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incendiary Ammunition
Incendiary ammunition is a type of ammunition that contains a chemical that, upon hitting a hard obstacle, has the characteristic of causing fire/setting flammable materials in the vincinity of the impact on fire. World War I The first time incendiary ammunition was widely used was in World War I, more specifically in 1916. At the time, phosphorus was the primary ingredient in the incendiary charge and ignited upon firing, leaving a trail of blue smoke. These early forms were also known as "smoke tracers" because of this. Though deadly, the effective range of these bullets was only 350 yards (320 m), as the phosphorus charge burned quickly. Incendiary bullets called "Buckingham" ammunition were supplied to early British night fighters for use against military zeppelins threatening the British Isles. The flammable hydrogen gas of the zeppelins made incendiary bullets much more deadly than standard ones which would pass through the outer skin without igniting the gas. Similar ...

Sellier & Bellot
Sellier & Bellot is a firearms ammunition manufacturer situated in Vlašim, Czech Republic. It is a subsidiary of the Brazilian company CBC. Foundation Sellier & Bellot was founded on August 5, 1825 by a German businessman of French origins called Louis Sellier. His family had been royalists who had fled France during the French Revolution. Louis Sellier began manufacturing percussion caps for infantry firearms in a factory in Prague, Bohemia on the request of Francis I, the Emperor of Austria. Sellier was soon joined by his countryman Jean Maria Nicolaus Bellot, who led the company to quickly gain momentum. Sellier & Bellot products soon established themselves on both European and overseas markets. As early as 1830 the manufacture of percussion caps was in excess of 60 million and peaked later in 1837 at the enormous quantity of 156 million caps.

Prvi Partizan
Prvi partizan ( sr, Први партизан, Prvi partizan; abbr. PPU) is a Serbian manufacturer of ammunition and handloading components, based in Užice, Serbia. The company produces ammunition for civilian and military consumers in a variety of calibers in various loadings. Several ammunition articles list Prvi partizan as one of the few sources of certain unusual cartridges, such as the 8x56mmR used in the M95/30 variant of the Mannlicher M1895, the 7.92×33mm Kurz cartridge used in the StG 44 rifle, and the 7.65×53mm Argentine cartridge. In early 2009, the company began manufacturing 8mm Lebel ammunition, becoming the first commercial manufacturer in decades to produce it. Headstamp Prvi partizan cartridges carry the headstamp "ППУ" ("PPU"), which stands as abbreviation of the company's name in Cyrillic letters, "Први партизан Ужице" ("Prvi partizan Užice").

CZ-52
The CZ 52 (also known by the Czechoslovak military designations vz. 52, for (vz. - ''vzor'' = model) "model of 1952", and CZ 482) is a semi-automatic pistol designed by two brothers, Jan and Jaroslav Kratochvíl, in the early 1950s for the Czechoslovak military. Around 200,000 vz. 52s were made by Česká Zbrojovka in Strakonice from 1952 to 1954. Before standardizing on the 7.62×25mm vz. 52, the Czechoslovak military used several domestic and foreign pistol models in three different calibers. After 30 years of military service, the vz. 52 was eventually replaced by the 9×18mm Makarov caliber vz. 82. The CZ 52 is technically known as the vz. 52; the Czech military designation. It's often referred to as the CZ 52 to differentiate it from the vz. 52 rifle, which entered the export market before the pistol. Description The CZ 52 pistol is a roller-locked short recoil–operated, detachable box magazine–fed, single-action, semi-automatic pistol chambered for the 7.62×25 ...

TT Pistol
The TT-30,, "7.62 mm Tokarev self-loading pistol model 1930", TT stands for Tula, Russia, Tula-Tokarev) commonly known simply as the Tokarev, is an out-of-production Soviet semi-automatic pistol. It was developed in 1930 by Fedor Tokarev as a service pistol for the Military of the Soviet Union, Soviet military to replace the Nagant M1895 revolver that had been in use since the Russian Empire, though it ended up being used in conjunction with, rather than replacing, the M1895. It served until 1952, when it was replaced by the Makarov pistol. Development In 1930, the Revolutionary Military Council approved a resolution to test new small arms to replace its aging Nagant M1895 revolvers. During these tests, on 7 January 1931, the potential of a pistol designed by Fedor Tokarev was noted. A few weeks later, 1,000 TT-30s were ordered for troop trials, and the pistol was adopted for service in the Red Army. The TT-30 was manufactured between 1930 and 1936, with about 93,000 being ...

9mm Winchester Magnum
The 9mm Winchester Magnum, which is also known as the 9×29mm, is a centerfire handgun cartridge developed by Winchester in the late 1970s. The cartridge was developed to duplicate the performance of the .357 S&W Magnum in an auto-pistol cartridge. The first handgun which chambered the cartridge was the Wildey pistol. Since then, Thompson/Center and LAR (Grizzly) have produced barrels chambered for this cartridge and AMT chambered their Automag III for it too, but the cartridge never reached the popularity enjoyed by other handgun cartridges. Starline Brass in Sedalia, Missouri, still make brass for this cartridge, although much of its production is now used to make 9mm blank firing cartridges for firearms chambered for 9×19mm, as this is easier to accomplish than using .223 Remington ( 5.56×45mm) cases, which may leave the neck area of the blank too thick to crimp properly. 9mm Winchester Magnum cases can also be trimmed and resized for reloading 9×25mm Mauser.

Bullet Trap
A bullet trap (or pellet trap when used specifically for air guns) is a device to stop and collect projectiles fired at a shooting range to prevent overpenetrations and stray shots. Bullet traps typically use friction, impact or gradual deceleration to stop bullets. The bullet trap may also provide means to recycle bullet materials and/or prevent release of toxic heavy metals (such as lead dust from fragmented bullets) from the shooting range. Some bullet traps include a negative-pressure system to filter dust from air within the impact zone and/or capture area. Deceleration traps Deceleration-type bullet traps direct bullets into a helical or circular chamber in which the bullet will slide against the curved chamber wall until it gradually loses velocity from friction and drops to the bottom of the chamber, where it can be later collected. For use with multiple firing positions, the helical chamber often resembles a horizontal pipe, into which bullets are directed by uppe ...

Personnel Armor System For Ground Troops
Personnel Armor System for Ground Troops (PASGT, pronounced ) is a combat helmet and ballistic vest that was used by the United States military from the early 1980s until the mid-2000s, when the helmet and vest were succeeded by the Lightweight Helmet (LWH), Modular Integrated Communications Helmet (MICH), and Interceptor Body Armor (IBA) respectively. Designed in the mid-1970s as a replacement for the M1 helmet and previous fragmentation vests, prototypes of the PASGT were tested in the late 1970s before being fielded in the early 1980s. In the early 2000s, the PASGT vest began being replaced by the IBA and the PASGT helmet was replaced soon thereafter with the LWH and MICH. As of 2018, the only remaining U.S. military users of PASGT in any capacity are the U.S. Army Reserve and the U.S. Navy, the latter of which retains the PASGT helmet for use by sailors aboard its warships, in addition to a PASGT-derived vest known as the "U.S. Navy Flak Jacket". Name PASGT is an acronym, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
