during the First World War, large-caliber sniper rifles then it was British weapon chambered for .600 Nitro Express earned the highest accolades. Such weapons are allowed for the destruction of the enemy at those distances, from which he could not respond normally, and even fight his light armored vehicles.
Between Interbelluma big bore gradually turned into anti-tank gun. Combat effectiveness in the defeat of manpower and light machinery eventually even led to the emergence of the term anti-materiel rifle, which is often translated literally -antimaterial rifle. Of course, in this translation lost a lot of meaning material -material part, the technique, but it sounds very interesting and even partly true.
sniper weapon is not easy and only by industrialized countries. There are minor exceptions, but to create a completely new design and new ideas only by leading countries. One of them is Austria. There the company Steyr Mannlicher famous near their successful development.
Widely known for their rifle SSG59, but now we are talking about the larger caliber weapons. In 2004 Austrian gunsmiths first presented to the public a new 12.7 mm sniper rifle with index HS .50 . Tactical application features such weapons allowed designers greatly facilitate this rifle: it is no automation and even shop. Single cartridge charging it through the window in the receiver, as it was on some anti-guns from World War II.
as ammunition for the proposed HS .50 cartridge 12.7 mm h99, but also possible completion under a completely new cartridge .460 Steyr. Interestingly, the U.S. law does not allow ordinary citizens to sell poldyuymovuyu version rifle. Variant chambered .460 Steyr, in turn, is available for purchase.
chambering a cartridge and removing the spent cartridges provided by the sliding bolt "hand-driven." Locking barrel is made on the two lugs in front of the gate. Window for insertion and extraction of the cartridge sleeve located in Picatinny rail for mounting the optical sight. Because of this when working with a rifle sight, nothing hurts and knocks it down.
powerful patron demanded apply several measures to reduce the impact. This three-chamber muzzle brake and adjustable spring-loaded butt plate. On the butt also has a height-adjustable cheek pad arrow. Corresponding optical sight and bipod allow sniper fire at ranges up to one mile.
A few years after the presentation of the original HS .50 was created its modification called HS .50 M1 . Its design has undergone significant changes. Overview -Introduction to design detachable box magazine for five rounds. Shutter remained almost unchanged.
Furthermore, the upper Picatinny rail is longer and the customer can install straps on the sides lodge. Regarding the supply of all modifications HS .50, there is almost no information. What is known is that in 2006 Iran ordered 700 or 800 of these rifles. Was made order -already known.
12,7-mm sniper rifles are certainly interesting, but they have ceased to be a rare weapon. Due to their types have long runs into tens. All the same Steyr once experimented with a larger caliber. In the 80s of the last century Austrian gunsmiths have created two interesting sample. The first of these was called AMR 5075 and was designed by Austrian copy Soviet patron h114 14.5 mm, and the second -IWS 2000 -intended for experimental cartridge h169 15.2 mm. Consider the second.
name IWS 2000 is interpreted as follows: "Infantry Weapon System 2000" -Infantry weapons system, two thousand. Apparently, Steyr planned to the aforesaid deadline to start promoting his rifle on the market. Uniquely large caliber hinted that IWS 2000 is not designed to engage manpower, although the effect of entering the human body without any doubt will be quite remarkable.
Because of the whole "spectrum" purposes in this case there was only lightly armored vehicles, and had to create a new cartridge. 15.2-mm cartridge APFSDS, as rifle itself is worth a separate story. The fact that it is composed of the bullet and a discarding sabot tungsten feathered arrow.
When caliber body arrows in 5.5 mm and weight of about 30 grams of it at a distance of 1000 m can penetrate up to 40 mm steel homogeneous armor. Due to the high initial velocity and good aerodynamics when shooting arrows at a distance of 1000 meters trajectory in its entirety does not rise above 800 mm above the line of sight.
If you need to fire unarmored vehicles or manpower, the effective range of the battle rifle is increased to two kilometers. This is mainly achieved by high-velocity bullets -about 1500 m/s.
It should be noted, term "rifle" in relation to the IWS 2000 is not entirely correct, because it does not have the barrel rifling and stabilize bullet-arrow in flight is achieved by untwisting her tail . Large Muzzle velocity and large caliber demanded relatively long barrel. At 2000 IWS it has a length of 1200 millimeters. Needless to save even a little handy dimensions weapons had to make the scheme a bullpup.
also because of its originality particular interest is automatic with long recoil. Chambering the first cartridge from the box magazine is attached to the right at an angle of about 45 ° manually. After the shot the barrel along with the shutter is rolled back about 20 cm back. Then turns around and unlocked the gate. He remains in the rear position, and the trunk goes along the path of ejecting the spent case.When
barrel returns to the forward position, automatic shutter releases. Moving forward, it shall be sent the next cartridge and locks the bolt. After pressing the shutter cycle repeats. Look such a complex system was used to "stretch" out for a while. With this shooter feels significantly less impulse than without such a system.Also
recoil reduction is achieved through the development of the muzzle brake and hydropneumatic recoil device. As a result, shooting arrow IWS 2000 "kicks" is not stronger than that of other large-caliber rifles. Sniper weapon weighing about 18 kg for the convenience of a biped folding bipod. Carrying IWS 2000 is broken down into two bales, backpack that allows to transport its forces calculation.
Unfortunately, for some military and fortunately for others, "Rifle" IWS 2000 and remained experimental and showpieces. Currently Steyr continue work on its improvement, lower returns, expand the range of ammunition, etc.
Artisans separatistsAt the beginning of the article
said that the creation of a sniper weapon only by developed countries. But there are exceptions, and it is very interesting. In the early `90s, when one would expect about Chechnya`s secession from Russia, thence separatists have mastered the production of large-caliber sniper rifles of his own design. On surviving Chechen enterprises in almost primitive conditions on the basis of serial samples made rifles family Al-Battar in Arabic "The Sword of the Prophet".
In the hands of the Russian military as a trophy rifle got two options -Al-Battar and Al-Battar II. From each other, they differ 12.7 and 14.5 mm, respectively, and other things associated with it. Both rifles had a similar design with the sliding bolt. Even bipod fastened to the same place -at the front of the receiver.
In turn, supply depot first and second rifle family was different. Al-Battar "was completed" box magazine of five cartridges, and Al-Battar II was charged manually on one cartridge. Out on samples captured scopes. Most likely, this was due to a forced "nature" rifles. Both open sight "Al-Battar" had only two positions, 500 and 1000 meters, which is clearly not enough for professional sniping, but enough for sabotage attacks.However, poor quality
sighting devices can be more than compensated by the caliber of the weapon. With the most important manufacturer and complex parts with a sniper rifle -barrel -Chechen gunsmiths are not wise. These details are simply filmed with DShK 12.7 millimeters and 14.5 mm KPV. There is information that the manufacture of rifles Al-Battar used weapons captured with padded armor federal forces.
As it is clear from the ammunition used cartridges 12.7 ? 108 mm and 14.5 mm h114, return both Chechen caliber rifles very, very significant.
Of course, in this article I have described, not all samples large-caliber sniper rifles. Yes, and 12.7, 14.5 or 15.2 millimeter do not pull on an absolute record. As for the records, the most "cool" at the moment of small arms systems are 30-mm "rifles" Maadi Griffin 30 mm cartridge 30h173 mm and Russian SP-30 rifle cartridge 30h165.
But in any directory on the subject of small arms clearly states that Firearms has caliber to 20 millimeters, and all that great -is artillery . So IWS 2000 can rightly be called the champion of small arms.
