There is an old saying among artillery men that their weapon is not the gun. It is the ammunition/shell, and the gun is only the last stage in transportation from the factory to the target.

The same applies to all fire arms as they are merely devices for discharging bullets, shells, bombs/projectiles of one sort or another which are the things destined to have the desired effect on the enemy target. Without ammunition the finest firearm is merely an expensive club or at best, a handle for a bayonet, while a piece of artillery with no ammunition is no more than an ornament. 2.But for all its importance, ammunition is usually taken for granted : received, loaded, fired and if it does not work the firer gets more aggrieved even if he does not know why it failed.

Yet it is a fascinating topic on its own. Many a weapon which appeared to have reached the end of its usefulness has been revitalized and given a new lease of life by nothing more than redesigning the ammunition for it, and many weapons have their effectiveness enhanced by new and improved ammunition.It is impossible to have a complete understanding of a weapon unless there is complete understanding of the ammunition as well. 3. The conflict in Afghanistan, Iraq and the Kargil war with its emphasis on targeting specific enemy individuals while avoiding collateral damage, demands the use of wpns of high precision and limited destructive effect.

As a result, inf small arms have a much more prominent role than that expected in conventional high-intensity warfare and this is highlighting the performance of their amn to a greater extent than ever before.Now that several nations have started the process of defining their reqmts for the next generation of small arms, this is a rare opportunity to ask the question: is the present combination of 5. 56 and 7. 62 mm rifle and machine gun amn optimal, or could we do better in the next generation.

1 PART – I BRIEF HISTORY 3. Although ammunition has been in existence since the initial days of firearms in the 14th century, it remained at a fairly static stage of development for the first 400 years.It was not till the industrial revolution got into stride in the mind-19th century that gun design began to show some advances, and with this came improvements in ammunition. The activity of designers and manufactures in the 1880s and 1890s showed its effect is South Africa and Russo- Japenese wars of the early 20th century.

These wars led to improvements and innovations development its greatest impetus. The First World War produced new techniques of warfare which demanded new type of ammunition.The arrival of military aircraft, for example, brought the first aerial bombs, but is also led to the development of special ammunition of shooting at the aircraft that were dropping these bombs. Old ammunition used during the early 17th century 4. Bullets for black powder, or muzzle loading firearms, were classically molded from pure lead. This worked well for low speed bullets, fired at velocities of less than 300 m/s (100 ft/s). for slightly higher speed bullets fired in modern firearms, a harder alloy of lead and tin or typesetter’s lead (used to mould Linotype) works very well.

For even higher speed bullet use, jacketed coated lead bullets are used. The common element in all these, lead is widely used because it is highly dense, thereby providing a high amount of mass and thus, kinetic energy for a given volume). Lead is also cheep, easy to obtain, and melts at a low temperature, making it easy for use in fabricating bullets. 5.

The advances made during the First World war were consolidated and refined during the 1920s and 1930s to design the standard ammunition types with which the Second World war begun.But once again, advance in military tactics and technology brought new forms of warfare and new types of ammunition. Improvements in the tank technology brought about improvements in anti-tank projectiles, higher-flying aircraft demanded new type of shell and fuse, portable infantry anti-tank weapons had to be given special projectile capable of defeating tanks, and so on. 2 PART II- RELATED TERMS AND EXPLANATION 6. Bullet The various types and characteristics of bullet are as follows (a)LeadSimple case, extruded, swaged, or otherwise fabricated lead slugs are the simplest form of bullets.At speeds of greater than 300m/s (common in most handguns), lead is deposited in rifled bores at an ever-increasing rate. Alloying the lead with a small percentage of tin and or antimony serves to reduce this effect, but grows less effective as velocities are increased. A cup made of harder metal, such as copper, placed at the base of the bullet and called a gas check, is often used to decrease lead deposits by protecting the rear of the bullet against melting when fired at higher pressures, but this too does not solve the problem at higher velocities.

Lead bullets used in the early 18th century (b)Jacketed Lead Bullets intended for even higher-velocity applications generally have a lead core that is jacketed or plated with cuprous-nickel, copper alloys, or steel, the thin layer of harder copper protects the softer lead core when the bullet is passing through the barrel and during flight, which allows delivering the bullet intact on the target. There the heavy lead core delivers its kinetic energy to the target.Full Metal jacket bullets or Ball bullet have the front and sides of the bullet completely encased in the harder metal jacket.

Some bullet jackets do not extend to the front of the bullet to aid in expansion and increase lethality. These are called soft points or hollow point bullets. Steel bullets are often plated with copper or other metals for additional corrosion resistance during long periods of storage. Synthetic jacket materials such as nylon and teflon have been used with limited success. 3 Jacketed Lead bullets c)Armour Piercing Jacketed designs where the core material is very hard, high-density metal such as tungsten, tungsten Carbide, depleted Uranium, or Steel.

A pointed tip is often used, but a flat tip on the penetrator portion is generally more effective. Armour piercing bullets (d)Tracer These have a hollow back, filled with a flare material. Usually this is a mixture of Magnesium Perchlorate, and Strontium salts to yield a bright red colour, although other materials providing other colours have also sometimes been used. Tracer material burns out after a certain amount of time.

Such ammunition is useful to the shooter as a means of verifying how close the point of aim is to the actual point of impact, and for learning how to point shoot moving targets with rifles. The flight characteristics of tracer rounds differ from normal bullets, decreasing in altitude of the flare material. 4 M196 Tracer ammunition (e)Incendiary These bullets are made with an explosive or flammable mixture in the tip that is designed to ignite on contact with a target. The intent is to ignite fuel or munitions in the target area, thereby adding to the destructive power of the bullet itself.M191 Incendiary ammunition (f)Frangible Designed to disintegrate into tiny particles upon impact to minimize their penetration for reasons of range safety, to limit environmental impact, or to limit the shoot-through danger behind the intended target. An example is the glaser safety slug. 5 Glaser safety slug (g)Practice Made from lightweight materials like rubber Wax, wood, plastic, or light weight metal, practice bullets are intended for short-range target work, only.

Because of their weight and low velocity, they have limited range. German Plastice practice ammunition h)Blanks Wax, paper, plastic, and other materials are used to simulate live gunfire and are intended only to hold the powder in a blank cartridge and to produce noise. The ‘bullet’ may be captured in a purpose-designed device or it may be allowed to expend what little energy it has in the air. Some blank cartridge are crimped or close at the end and do not contain any bullet. 6 7. 62mm blank ammunition 7. PRIMER (a)Percussion Cap The percussion Cap, introduced around 1830, was the crucial invention that enabled muzzle loading firearms to fire reliably in any weather.Before this development, firearms used flintlock ignition systems which produced flint-on-steel sparks to ignite a pan of priming powder and thereby fire the gun’s main powder charge.

(The flintlock mechanism replaced older ignition systems such as the matchlock and wheel lock). Flintlocks were prone to misfire in wet weather, and may flintlock firearms were later converted to the more reliable percussion system. The percussion cap is a small cylinder of copper or brass with one closed end.

Inside the closed end is a small amount of a shock-sensitive explosive material such as fulminate of mercury.The percussion cap is placed over a hollow metal “nipple” at the rear end of the gun barrel, pulling the trigger releases a hammer which strikes the percussion cap, and ignites the explosive primer. The flame travels through the hollow nipple to ignites the powder charge. Percussion caps were (and still are) made in small sizes for pistols and larger sizes for rifles and muskets. In the 1850s, the percussion cap was first integrated into a metallic cartridge, which contained the bullet, powder charge and primer.

By the late 1980s, breech loading metallic cartridges had made the percussion cap system obsolete.Where subsequently introduced into breech loaded cartridges, the percussion cap became known as a Primer. Largely the presence of the weak single nitrogen-oxygen bond which leads to its instability. Nitrogen very easily forms a stable triple bond to another nitrogen atom, forming gaseous nitrogen.

Today mercury fulminate tends to be replaced by other primary explosives which are less toxic and more stable over time. Lead azide, lead styphnate and terazene derivatives. 7 Percussion cap Breech loaded metallic revolver 8. Cartridge Case Brass is generally used. Brass has higher malleability than copper or zinc.The relatively low melting point (900 – 940 C depending on composition) of bras and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses.

Today almost 90% of all brass alloys are recycled. Because most brass is nonmagnetic, it can be separated form ferrous scrap by passing the scrap near a powerful magnet. Brass scrap is collected and transported to the foundry where it is melted and recast into billets. Billets are later heated up and extruded in to the right from and size.Brass cartridge cases 8 9. Linear Thermal Expansion Coefficient The Linear Thermal Expansion Coefficient relates the change in temperature to the change in a material’s linear dimensions. It is the fractional change in length of a bar per degree of temperature change.

The expansion and contraction of material must be considered when designing large structures, when using tape or chain to measure distances for land surveys, when designing molds for casting hot material, and in other engineering applications when large changes in dimension due to temperature are expected.Some values of common materials, given in parts per million per Celsius degree (Note : This can also be in Kelvins as the change in temperature are a 1:1 ration). 9 PART III- AMN USED IN INDIA 10. India possess the 7.

The 7. 62mm round can penetrate a window pane at a 45 degree obliquity, a hollow cinder block, or both sides of a car body. At 50 meters, the 7. 62mm ball round cannot reliably penetrate a single layer of well-packet sandbags. It can penetrate a single sandbag layer at 200 meters, but not a double layer. The armor-piercing round does only slightly better against sandbags. It cannot penetrate a double layer but can penetrate upto 10 inches at 600 meters.

The penetration of the 7. 62mm round is best at 600 meters. Most urban targets are closer . the longest effective range is usually 200 meters or less. 17 Penetration capabilities of a single 7.

Continued and concentrated machine gun fire can breach most typical urban walls. uch fire cannot breach thick reinforced concrete structure or dense natural stone walls. Internal walls, partitions, plaster, floors, ceilings, common office furniture, home appliances, and bedding can be easily penetrated by 7.

62mm rounds. Armour Piecing Round 30. Armour-piercing ammunition is used to penetrate hardened armored targets such as body armor, vehicle, concrete, tanks and other defenses, depending on the caliber of the firearms.

Armor-piercing ammunition consists of a hardened steel, tungsten-carbide, or depleted uranium penetrator enclosed within a softer material, such as copper or aluminum.Armor-piercing ammunition can range form rifle and pistol caliber rounds all the say up to tank rounds. 31. Rifle and pistol rounds are usually built around a penetrator of steel or tungsten.

Aircraft and tank rounds sometimes use a core of depleted uranium. The penetrator is a pointed mass of high density material that is designed to retain its shape and carry the maximum possible amount of energy as deep as possible into the target. Depledted- uranium, penetrators have the advantage of being pyrophoric and self-sharpening on impact, resulting in incredible heat and energy focused on a minimal area of the target’s thicker armor.

Rifle armour-piercing, ammunition generally carries its hardened penetration within a copper or cupro-nickel jacket, similar to the jacket that would surround lead in a conventional projectile. Upon impact on a hard target, the copper case is destroyed, but the penetrator. 34.

The M993 7. 76mm AP Round is capable of penetrating a 7mm thick high hardness armor (HHA) plate at a distance of 500 meters from the muzzle of the weapon. This corresponds to ? “ armor plate at a distance of 550 m. High Explosive Incendiary/Armor Piercing Ammunition 35.High Explosive Incendiary/Armor Piercing Ammunition (HEIAP) is a form of shell which combines both an armor piercing capability and a high explosive effect. In this respect it is modern version of armor piercing shell. Typical of a modern 18 HEIAP shell is the Raufoss MK 211 0.

50 inch round designed for anti-material weapons such as heavy machine guns and anti-material rifles. 36. The primary purpose to these ammunitions is armor penetration, but unlike SLAP rounds (Saboted-Light Armor penetrator) which gets their armor piercing ability from the propulsion of a 7. 62mm tungsten heavy alloy bullet from a 12.

mm barrel (. 50”csl). with much more energy than is usually possible from a 7. 62mm round (plus the fact that a tungsten alloy bullet will completely destroy the rifling of the barrel-hence the plastic sabot), the HEIAP munitions use explosives to “blast a path” for the penetrator. 37.

The round is loaded just as solid full metal jacketed round would be. The special effect is developed when the around strikes the target. The initial collision ignites the incendiary material in the tip. Triggering the detonation of the HE charge. The second (zirconium powder) incendiary charge ill also ignite. This burns at a very high temperature and is not readily extinguished and can last for 30 seconds. 38.

The remaining element of the ground is the tungsten carbide penetrator. This has a large kinetic energy and will penetrate the armour as solid-cored armour piercing shot would. This would take some of the incendiary round through the armor. The MK 211 is claimed to penetrate up to 2 inches (50mm) of rolled steel. 19 APDS and SLAP 39. SLAP (Saboted Light Armor Penetrator) and APDS (Armor Piercing Discarding Sabot) are two names for the same type of ammunition.However, the “SLAP” acronym is usually reserved for small caliber ammunition (less the 20mm), while “APDS” is more common for medium or large caliber ammunition.

40. There are two parts in a SLAP/APDS payload. The first part is the armor-piercing (AP) bullet itself. This consists of a sub-caliber bullet (sometimes called a flechette, dart, or penetrator) usually made out of particulary hard and dense metal or metal alloy, such as tungsten carbide. The second part of a SLAP/APDS payload is a discarding sabot (DS).

This is a plastic coller that fits between the sub-caliber penetrator and the rifle’s bore, transferring spin from the rifling to the sub-caliber penetrator. The sabot lightens the load that the propellant charge must push from the barrel, increasing the bullet’ss velocity substantially. This higher velocity facilitates greater penetration. 41. Shortly after exiting the muzzle, the sabot is stripped from the bullet by centrifugal forces and wind resistance, leaving the bullet free to move down range independently from the sabot. SPECIAL PURPOSE SMALL ARMS AMMUNITION 42.

Ammunition for Silenced WeaponsThe SP-2 ammunition, which was the first to be produced in any quantity, has been based on 7. 62×39 case, slightly shortened and fitted with round-now 7. 62mm bullet (most probably similar to one used in 7. 62×25 TT cartridges). Internally this cartridge contained a small charge of propellant behind a two-stage telescoped piston, which propelled the bullet out of the case when fired and then locked the hot powder gases inside the case. The resulting sound was almost non-existent, and the cartridge was adopted by the KGB for clandestine operations.

To improve performance and some what confuse possible investigators, the round-nose bullet was later replaced by a standard pointed 7. 62mm bullet originally used in 7. 72×39 M 43 ammunition.

This cartridge designated 7. 62 x 38 SP-3 has been in use since the early 1970, along with the MSP two – barreled derringer type pistol and NRS –1 scout shooting khnife. While the SP-3 cartridge was more or less adequate for the clandestine work of the KGS, it was far too underpowered for use by elite Spentsnaz units, which were supposed to operate deep behind enemy lines.To provide the Spetsnaz with a more potent weapon, Soviet designers developed an enlarged version of the SP-3 cartridge, initially know as PZ, which latter involved into the PZA and PZAM 7. 62mm silent cartridge. Used in the S-4M”Groza” (Thunderstorm) tow-barreled break-open pistol, 20 the 7. 62×63 PZAM cartridge has a very strong, thick walled, slightly bottle necked case with a tow-stage telescoped piston, similar to the SP-3. It is loaded with the same 7.

62 pointed M43 bullet. It has been used by Soviet Spetsnaz forces in Afghanistan.The SP-6 cartridge featured an armour-piercing bullet with a hardened steel core, which could defeat typical military-type body armour at ranges of up to 300-400 meters. 43. Underwater Weapons The next line of development, almost unique to the Soviet armed forces, has been underwater firearms and ammunition for them.

Initially developed during the late 1960s, underwater cartridge propelled the long and slim drag-stabilized bullets, and were used in four barreled SPP-1 break-open pistols.To achieve better loading and extraction, the bottlenecked brass cartridge were rimmed and loaded using special flat clips, which held all four rounds together. Both primer pockets and case necks were sealed against the water, and the steel bullets were covered by special lacquer coating. Initially satisfied with the pistol, Special forces elements of the Soviet Navy requested further development and by the mid 1970s Soviet designers brought in a unique underwater assault rifle, the APS(which, in fact, was a smoothbore weapon).This weapon used cartridge externally similar to earlier SPS pistol ammunition, but based on the standard 5. 45×39 M74 cases. This “rifle” ammunition is available in two basic forms, MPS “ball” and MPST “tracer”.

Both APS underwater automatic weapon and SPP-1 M underwater pistol are still in used by Russian navy, as well as offered for export. 7. 62mm SP-3| 7. 62X38| 8| Not published| Silent Cartridge| 7. 62mm SP-4| 7. 62×41| 9. 3| 260| Silent Cartridge| 7.

VOG-17This round is intended for firing from the AGS-17 and AGS-30 automatic grenade launchers to engage manpower and war material. The grenade launcher is used to arm motorized rifle units. It can also be installed on helicopters, motor boats and vehicals.

The grenade launcher is designed for flat and curved fire. The around is provided with an instantaneous point fuze ensuring reliable functioning of grenades on impact, including with snow and water surface. The enhanced fragmentation is obtained owing to weakening grooves on the internal surface of the grenade body. 2 PART VI – AGL AMMUNITION OF THE WORLD Air Burst Round 45. An air burst round is a bullet that detonates in mid air, causing shrapnel demage to an enemy.

This makes it easy to hit enemy soldier behind a wall, in a foxhole, or in a confined space or room. It is used o many guns including the XM-29 assault rifle. On many guns like XM-29, it is 20mm and is similar to a smart grenade.

Although useful in many situations. It is not as effective as a hand or launcher grenade and its fragments are not as dangerous but is still a very dangerous weapon.To fire it simply set the distance you want to detonate, fire and watch the round explode in mid air.

M430 HEDP (High Explosive, dual purpose) 46. The HEDP (High explosive Dule Purpose) M 430 cartridge joined with M 16 A2 links is the standard round for the MK-29.

The impact-type round penetrates 2inches of steel armor at 0 degree obliquity and inflicts personnel casualties in the target area. This round is packed in am M 548 ammunition container (48 rounds, linked, in each container). It is olive drab with a yellow give and yellow markings.

It has a PIBD M 549 fuze and comp B filler. It arms between 18 to 30 meters and has a casualty radius of 15 meters. 23 M430 HEDP (High Explosive, dual purpose) Identification Olive drab with yellow olive and yellow markings. Fuze Point initiating base detonating (PIBD) M549 Filler – Composition B Arming distance – 18 to 30 meters 23Kill radius – Approximately 5 meters Maximum range – 2200 meters. Wound radius – Approximately 15 meters. Maximum effective range – 1500 meters. SM 1018 HIGH EXPLOSIVE AIR BURSTING (HEAB) 47. The key to delivering the revolutionary increase in lethality and survivability of the Objective individual Combat Weapon (OICW) was the precision XM1018 High Explosive Air Bursting (HEAB) ammunition.

It consists of a center-body fuze with a controlled fragmenting warhead on each end. This design was chosen to maximize lethality. This is a very challenging system to develop and test but was successfully demonstrated multiple times.The key technologies and integration drivers being addressed included miniaturized and gun hardened fuze electronics, ammunition reliability, a “men-rated” safe and arming system, system interfaces between the weapon, fire control, and ammunition, dual warhead lethality, uniform ammunition 24 propulsion, and weapon recoil mitigation. What makes this system unique is its ability to provide all-electronics information on range, to automatically. All the soldier has to do is aim, lase, adjust his/her aim point, and fire the calculations are transparent to the user. 48.

The HEAB ammunition will have a settable fuze that interacts with the TA/FCS automatic fuze programming. It will have the necessary lethal radius to insure the required P (i) s are met. The HEAB ammunition shall demonstrate a minimum reliability of not less that that of the current 40-milimeter M406 HE/M433 HE Dual Purpose (HEDP) cartridge.

A family of cartridge for the HE portion of the weapon will be developed including an inert cartridge for training, as target practice spotter cartridge which indicates actual burst location, and a blank cartridge for force on force training.
