The M200 .408-inch caliber sniper rifle of the American company Cheytac can, under ideal conditions, shoot at the human head without correction at a distance of 2,000 meters. The world's longest range sniper rifle - M200[6P] Ideal conditions It can shoot at the human head without correction at a distance of 2,000 meters. On July 13, 2004, Richard Marcovis, a former sniper of the US Navy SEALs, selected a standard steel target 2,122 meters away for shooting. , the first three shots were distributed within 42.2 centimeters, setting a new world record. The record for the farthest single shot previously recognized by the world was set by the Canadian Forces in 2002. A Canadian sniper used a Tac-50 sniper rifle from the American company McMillan. After a correction, he killed a Taliban at 2,430 meters away. . The M200.408-inch caliber combines the accuracy of .338 with the power of .50. It is a patented caliber ammunition specially designed for Cheytac's firearms products. However, M109 came from behind. For some long-distance sniper missions, the power of common 12.7mm caliber bullets insufficient. As a pioneer in advocating the development of 12.7mm caliber sniper rifles, Barrett Company has recently designed and manufactured a 25mm Ten weapon prototypes have been produced for recent testing. The XM109 sniper rifle, which has the ability to destroy light armor, is a semi-automatic 25mm rifle with a barrel length of 447mm and a total length of 1168mm. It weighs about 20.9 kg and is equipped with a magazine with a capacity of 5 rounds. The Barrett M107 12.7mm caliber sniper rifle has a barrel length of 960mm, a total length of 1448mm, a weight of about 15 kilograms, and a magazine with a capacity of 10 rounds. The part of the bipod equipped with the XM109 sniper rifle that touches the ground adopts a spike-like design to support the sniper rifle and keep the XM109 stable when shooting. There is also a standard Picatinny M1913 accessory rail for mounting other accessories. In addition to selling a complete set of XM109 sniper rifles, Barrett also provides upgrade parts such as replaceable bolts, receivers and magazines for converting the M107 12.7mm caliber sniper rifle to 25mm caliber. In order to enhance the accuracy of the XM109 sniper rifle, a very advanced computer data processing sight system is used, called the "Barrett Optical Range Correction Sighting System" (BORS). The main application range of this system is 1,000 meters and more. The long distance makes the gun more capable of long-distance shooting. The system collects data related to target measurement and correction such as air pressure, temperature and weapon angle, and processes and calculates them. Accurately correcting all of these factors improves the accuracy of the first bullet hitting the target. The system calculates the point of impact of the first bullet, and all the shooter has to do is use a dial to align the target at a distance, select the ammunition type, and align the crosshair on the target. The latest models in the future will incorporate rangefinders and night vision capabilities. The XM109 sniper rifle has an effective range of approximately 2,000 meters. The 25mm bullet used is derived from the M789 high-explosive dual-purpose (against armor and personnel) 30mm ammunition used on the AH-64 "Apache" helicopter. It can penetrate at least 50mm of armor steel plates and has the ability to destroy light armored vehicles, Information transmitting devices and other equipment. According to ammunition manufacturers, 25mm bullets are more effective at destroying targets, more than 2.5 times more powerful than 12.7mm armor-piercing bullets. Operation: Semi-automatic Barrel length: 447mm Spiral rifling: 1 lead 558mm Rifle weight: 20.9 kg The modular structure design makes improvements more convenient and meets the ever-changing battlefield needs. Supplies: two 5-round magazine tripods: spike-shaped, adjustable, detachable and detachable bipods that can be disassembled with bare hands; the "heavy weapons" among the above three sniper rifles should be called sniper guns according to the standard Yes, its ultra-long range and excellent armor-piercing capabilities are a terrible nightmare for mechanized infantry. Especially in urban street fighting, the chaotic battlefield environment provides numerous shooting positions for snipers. In future wars, a sniper with a large-caliber sniper cannon will be able to delay or even destroy an armored company's attack.
However, due to excessive emphasis on caliber, these big guys are extremely heavy and may hinder snipers when moving positions. This may also be a nightmare for snipers who "shoot once and change places." In addition, because the sound and smoke when fired are relatively loud, it also provides the opponent's sniper with the opportunity to easily find the target. Therefore, shooters using these sniper cannons are more dangerous than shooters using ordinary sniper rifles.
