Design

The PTRS-41 was produced and used by the Soviet Union during World War II. In the years between the World Wars, the Soviet Union began experimenting with different types of armour-piercing anti-tank cartridges. Finding the 12.7x108mm insufficient, they began development of what would become the 14.5x114mm armour piercing round. Famous Soviet weapons designers such as Vasily Degtyaryov and Sergei Gavrilovich Simonov designed rifles to accommodate this cartridge. In 1938, Simonov designed the PTRS-41, a magazine fed, anti-tank rifle.
The five round magazine was loaded into the receiver and held under pressure by a swing magazine underneath. On firing the last round, the bolt is held open, and the magazine release catch can only be operated when the bolt is locked back. The gas-operated PTRS has a tendency to jam when dirty, and the 14.5 mm cartridge produces significant residue, blocking the gas port. The 14.5 mm armour-piercing bullet has a muzzle velocity of 1012 m/s and good ballistics. It can penetrate an armour plate up to 40 mm thick at a distance of 100 meters.

Boys anti-tank rifle


Boys anti-tank rifle

The Rifle, Anti-Tank, .55in, Boys commonly known as the "Boys Anti-tank Rifle"was a British anti-tank rifle. The Boys is often incorrectly spelled "Boyes". There were three main versions of the Boys, an early model (Mark I) which had a circularmuzzle brake and T shaped bipod, built primarily at BSA in England, a later model (Mk I*) built primarily at Jonathan Inglis in Toronto Canada, that had a square muzzle brake and a V shaped bipod, and a third model made for airborne forces with a 30-inch (762 mm) barrel and no muzzle brake. There were also different cartridges, with a later version offering better penetration.

History

It was a German weapon of World War I, appearing in February 1918. The MauserCompany began mass production at Oberndorf am Neckar in May 1918. The first of these off the production lines were issued to specially raised anti-tank detachments. The idea of using heavy calibre and high velocity rifles as anti-tank weapons originated in Germany. In 1917 the German Army, faced with the menace of a mobile fortress (the British heavy tanks), found they had no infantry weapon which could counter the threat.
The 13.2 x 92mm (.525-caliber) semi-rimmed cartridge, often simply called "13 mm", was originally planned for a new, heavy Maxim MG.18 water-cooled machine gun, the Tank und Flieger (TuF) meaning for use against "tank and aircraft", which was under development and to be fielded in 1919.
The anti-tank rifle can be found in several museums: Patton Museum in Fort KnoxIn Flanders Fields Museum in Ypres, the Imperial War Museum in LondonUnited KingdomKing's Own Royal Border Regiment Museum in the United Kingdom, the Army museum at the Invalides in Paris, and others.
Many modern rifles find their roots in the 13.2 mm Mauser, the most closely related being the Gepard rifle.

Luger P08 pistol


Luger P08 pistol

he Pistole Parabellum 1908 or Parabellum-Pistole (Pistol Parabellum), popularly known as the Luger, is a toggle-locked recoil-operated semi-automatic pistol. The design was patented by Georg J. Luger in 1898 and produced by Germanarms manufacturer Deutsche Waffen- und Munitionsfabriken (DWM) starting in 1900; it was an evolution of the 1893 Hugo Borchardt designed C-93. It would be succeeded and partly replaced by the Walther P38.
The Luger was made popular by its use by Germany during World War I and World War II. Although the Luger pistol was first introduced in 7.65x22mm Parabellum, it is notable for being the pistol for which the 9x19mm Parabellum (also known as the 9mm Luger) cartridge was developed.

Design details

The Luger uses a toggle-lock action, which uses a jointed arm to lock, as opposed to the slide actions of almost every other semi-automatic pistol. After a round is fired, the barrel and toggle assembly (both locked together at this point) travel rearward due to recoil. After moving roughly one-half inch (13 mm) rearward, the toggle strikes a cam built into the frame, causing the knee joint to hinge and the toggle and breech assembly to unlock. At this point the barrel stops its rearward movement (it impacts the frame), but the toggle and breech assembly continue moving (bending the knee joint) due to momentum, extracting the spent casing from the chamber and ejecting it. The toggle and breech assembly subsequently travel forward (under spring tension) and the next round from the magazine is loaded into the chamber. The entire sequence occurs in a fraction of a second. This mechanism worked well for higher pressure cartridges, but cartridges loaded to a lower pressure could cause the pistol to malfunction because they did not generate enough recoil to work the action fully. This resulted in either the breechblock not clearing the top cartridge of the magazine, or becoming jammed open on the cartridge's base.
In World War I, as submachine guns were found to be effective in trench warfare, experiments with converting various types of pistols to machine pistols(Reihenfeuerpistolen, literally "row-fire pistols" or "consecutive fire pistols") were conducted. Among those the Luger pistol (German Army designation Pistole 08) was examined; however, unlike the Mauser C96, which was converted in great numbers to Reihenfeuerpistolen, the Luger proved to have an excessive rate of fire in full-automatic mode.
The Luger pistol was manufactured to exacting standards and has a long service life.William "Bill" Ruger praised the Luger's 55 degree grip angle and duplicated it in his.22 LR pistol.

Winchester Model 1897


Winchester Model 1897

The Winchester Model 1897, also known as the Trench GunModel 97 and M97, was a pump-action shotgun with an external hammer and tube magazine manufactured by the Winchester Repeating Arms Company. The Model 1897 was an evolution of the Winchester Model 1893 designed by John Browning. From 1897 until 1957, over one million of these shotguns were produced. The Model 1897 was offered in numerous barrel lengths and grades, chambered in 12 and 16 gauge, and as a solid frame or takedown. The 16-gauge guns had a standard barrel length of 28 inches, while 12-gauge guns were furnished with 30-inch length barrels. Special length barrels could be ordered in lengths as short as 20 inches, and as long as 36 inches. Since the time the Model 1897 was first manufactured it has been used by American soldiers, police departments, and hunters.

History

The Winchester Model 1897 was designed by the famous American firearms inventorJohn Moses Browning. The Model 1897 was first listed for sale in the November 1897 Winchester catalog as a 12 gauge solid frame. However, the 12 gauge takedown was added in October 1898, and the 16 gauge takedown in February 1900. Originally produced as a tougher, stronger and more improved version of the Winchester 1893, itself a takeoff on the early Spencer pump gun, the 1897 was identical to its forerunner, except that the receiver was thicker and allowed for use of smokeless powder shells, which were not common at the time. The 1897 introduced a "take down" design, where the barrel could be taken off; a standard in pump shotguns made today, like the Remington 870. Over time, “the model 97 became the most popular shotgun on the American market and established a standard of performance by which other kinds and makes of shotguns were judged, including the most expensive imported articles”. The Winchester Model 1897 was in production from 1897 until 1957. It was in this time frame that the "modern" hammerless designs became common, like the Winchester Model 1912 and the Remington 870 and the Model 1897 was superseded by the Winchester Model 1912. However, the gun can still be found today in regular use.
