M33 General ammunition M82/M 107 is a standard ammunition, the warhead weighs 45.8g, the serial number is STD-OTCM 3684 1, and there is no identification color. The casing contains WC 860 double-base propellant 15.23g, and the bore pressure is 379MPa. At 500 meters, it can penetrate 8 mm thick steel plate. It can penetrate a steel plate with a thickness of 4mm at a height of 1200m. It is used against unprotected human targets. In the early period of M82/M 107, this kind of bullet has been used for long-range sniper. M33 bullet tip contains about 0.8 grams of sodium carbonate monohydrate. Sodium carbonate monohydrate is a white powder with a melting point as high as 8565438 0℃ and stable performance. After the bullet hit the target, it broke. The white powder is released to form smoke, which is convenient for the shooter to observe the impact point and then correct the trajectory. In contrast, when a tracer burns a tracer, its weight is constantly reduced during the flight, and its ballistic performance is unstable, which is different from ordinary bullets, which increases the difficulty of correcting the sight. This method of marking the impact point with smoke is more accurate. DODIC code A606, Norwegian Raufoss A-class competition bomb, is currently only adopted by USMC of the US Marine Corps and distributed to M82 shooters as standard ammunition. The initial velocity is 854m/s, and the effective range reaches 1800m when performing anti-equipment tasks. M8 armor-piercing bullet borrowed from M2HB Browning heavy machine gun, ammunition number OBS-MSR 1 1756003, silver bullet tip. The warhead weighs 40.34 grams and contains 0.97 grams of IM 1 1 combustion agent. Shell case loading 15.5438+00g. The bore pressure is 406MPa, the initial velocity is 88 1m/s, 550m/s, and the dispersion diameter of 550m is less than 25cm (about 1.7MOA). Steel plates with a thickness of 20mm can be penetrated at 100m, 500m and 1200m. M 17 tracer bullet number CON-MSR 1 1756003, chestnut bullet tip. The tracer brand is R256, and the tracer distance is 2450m. The casing is filled with 14.58g IMR 50 10 single base propellant, and the bore pressure is 372MPa. Although tracer bullets have the disadvantages of reduced warhead weight and unstable trajectory, they can still observe the impact point at night. M20 APIT armor-piercing incendiary bomb adds tracer function to M8 armor-piercing bomb. The number is OBS-MSR 04776009, and there is a gray circle under the red bullet tip. The weight of warhead is 40. 1 1g, and the bullet tip is equipped with1.75g im161g combustion. The tail of the warhead is equipped with R256 tracer with a range of 300~ 1750m. 500m can penetrate 2 1mm thick steel plate, and 1 1mm can penetrate 14.90g IMR 50650 thick steel plate. The NM 173 AP-S armor-piercing projectile is produced by Norwegian Ammunition Group and "Northern Ammunition Group" and is located in the village of Raufos, Norway, Finland, Germany, Norway, Sweden and the United States. Its initial velocity is 9 15m/s, and the dispersion diameter of 550m is less than 15cm (equivalent to 1moa). The steel plate with the thickness of 1 1mm can penetrate within a distance of 30. Mk2 1 1 Mod 0 API armor-piercing incendiary bomb number STD-FEB-1996. In fact, it is the NAMMO NM 140 MP multi-purpose bomb imported from the village of Raufos, Norway, which integrates armor piercing, burning and explosion. After the US military adopted it, it gave him a US military number-"MK.211Mod0" armor-piercing projectile, which was abbreviated as Raufos Mk.2 1 1 API. The tip of the warhead is painted green and a white circle (if you pay a little attention, you can see that the occurrence rate of this kind of bomb is very high recently). The warhead weighs 43.48 grams ... Combustion agent -0.85g # 136 zirconium-containing combustion agent (at room temperature, zirconium is very stable; At high temperature, powdered zirconium can burn in air); Explosive composition-0.84g A-4 mixed explosive (passivated RDX). The cartridge case is filled with WC 860, MR 50 10 or RA-NC- 167 propellant, the bore pressure is 387MPa, the initial velocity 15cm/s, and the projectile accuracy is high (the dispersion diameter of 550m is less than 650 m). The comprehensive damage efficiency is good (the combustion performance is jet fuel JP-8, which can produce 20 fragments when hitting a 2mm thick steel plate), and it can effectively deal with light armored targets (1000m thick steel plate can penetrate at a 45 angle). However, due to the high cost, it was mainly used by M 107, and the United States obtained the production right. At first, it was assigned to the M2 heavy machine gun. The warhead of the M 1022 long-range sniper bomb is painted green, which is specially developed for the M 107 rifle to deal with unprotected human targets. M903 SLAP is the abbreviation of "Light Armored Penetration Projector" for the light armored armor-piercing projectile, which was distributed to M2HB at 1993. M903 SLAP belongs to the sub-caliber armor-piercing projectile, and its working principle is the same as that of the sub-caliber armor-piercing projectile used by the tank main gun. The warhead adopts tungsten alloy armor-piercing core, with a diameter of 7.62 mm and a weight of about 23.3 grams. The outer part is made of plastic, and the warhead accelerates faster because of removing the redundant burden such as lead sleeve. When M903 SLAP armor-piercing projectile is fired with M2HB machine gun, the muzzle velocity of the warhead can exceed 1220m/s, even for M82/M 107 rifle with shorter barrel than M2HB. The initial velocity of launching M903 SLAP is also as high as 10 14m/s, which is much higher than that of launching Raufoss MK.21M82/M 107. The destructive power of M903 Slap is quite amazing: it can penetrate 34 mm thick hardened armor at 500 meters. At 1200m, the hardened armored steel plate with a thickness of 23mm can be penetrated. Hardened armored steel plate with thickness of 19mm can penetrate within the distance of 1500m; Mk2 1 1 can only penetrate the steel plate with the thickness of 1 1mm in the range of 1000m, and the difference in power can be seen. M962 SLAP-T armor-piercing projectile tracer is used together with M903 SLAP armor-piercing projectile to indicate trajectory. These are all military bombs. There are special requirements for trajectory consistency. After all, military rifles don't have enough time to calibrate guns on the battlefield. Only when different ammunition keeps the same trajectory can the sight play its role effectively. Therefore, the trajectory of the above bullets must match the trajectory of 12.7mm standard bullets (mainly M33). Therefore, the supersonic flight distance of military 12.7mm machine ammunition is only 1.500 ~ 1.600m Hornaday A-MAX competition ammunition. And some powerful civilian ammunition has no such scruples. For example, Hornady A-Max competition ammunition is a powerful civilian competition-grade bullet specially developed for long-range precision shooting, with high quality and high price, unlike M33. Ordinary machine gun bullets distributed in the army. The weight of the warhead reaches 48.6g (750gr, ballistic coefficient 1.05), which is 6% heavier than M33 military bullet, and the supersonic flight distance can reach 2250~2300m, although the muzzle velocity is slightly lower than M33 military bullet: it is fired with the barrel of M82 rifle with a length of 737mm, and the muzzle velocity of M33 military bullet is about 853m/. The muzzle velocity of Hornaday A-MAX is about 810m/s. In 2002, Canadian sniper Rob Furlong set a record of 2430m, using Macmillan TAC-50 rifle (not Barrett M82, I'm afraid some people will struggle). The American Hornady A-Max bullet was fired. TAC-50 rifle fired Hornady A-Max warhead with initial velocity of 823m/s, maximum range of about 828 1m, corresponding to the maximum range angle of 37 29' 37 "and flight time of 44.56438+0s.

50 caliber bullets, especially all-metal armor, can easily penetrate bulletproof vests below level 4 and many walls. In addition, the extra kinetic energy makes M82 more able to penetrate the 8-level hard armor and bulletproof glass to kill the target than the gun of the same level (very likely).
