A bullet is a projectile fired from a firearm and consists of several essential components that work together to propel it forward and cause damage to the target. Understanding the anatomy of a bullet is crucial for firearms. A bullet cartridge is a three-part vehicle with the actual bullet mounted on the very end. The traditional swaged lead core provides uniformity and balance for consistent performance and accuracy, while the nontraditional lead-free core (NTX) offers a more balanced design. Bullets typically contain lead or a lead alloy core and are often jacketed with copper or another metal.
The four basic but essential components of the modern cartridge are the bullet, powder, case, and primer. When put together correctly, they form a bullet. Bullets are conical in shape with a hollow cavity in the rear, fitted with a small iron cap instead of a wooden plug. The bullet’s purpose is to impart kinetic energy to the target, causing damage.
The casing holds a bullet together until it is fired or disassembled. Inside the casing, the primer, gunpowder, and bullet are enclosed in one cartridge. The primer is struck by the firing pin to ignite the bullet. A modern bullet consists of a tube (the cartridge case), the bullet at the front end, the percussion cap or primer at the base, and the propellant.
A bullet wipe is a discolored area on the immediate periphery of a bullet hole, caused by bullet lubricant, lead, smoke, bore debris, or possibly jacket. The bullet sides bear markings of the barrel’s interior rifling. Bullets are made of various materials, such as copper, lead, steel, polymer, rubber, and wax, and are made in various shapes and constructions.

What is inside ammo?
Ammunition consists of a case, primer, powder, and projectile. The case is a container made of brass, steel, or copper, which holds all other components together. Primer is an explosive chemical compound that ignites gunpowder when struck by a firing pin. Gunpowder is a chemical mixture that burns rapidly and converts to an expanding gas when ignited. A bullet is a projectile, usually containing lead, fired through a handgun barrel.
What is the powder inside bullet?
A bullet is defined as a projectile that exits the muzzle of a firearm without the use of gunpowder, with the powder contained within the cartridge. Modern cartridges utilize a smokeless powder, a blend of nitrocellulose and nitroglycerin, frequently in a 50:50 ratio.
What is the main ingredient in bullets?
A bullet is a projectile fired through a rifle or handgun barrel, while a slug is a solid projectile fired through a shotgun barrel. A shot is a group of lead, steel, tungsten alloy, or bismuth pellets fired through a shotgun barrel.

What part of the bullet holds the powder?
Bullets are small metal objects fired from guns, often made from lead covered with copper. They are placed in a cartridge, which is then inserted into a gun. The bullet is placed at the front of the cartridge, and hot gases at high pressure push it out of the gun. A powder called gunpowder is placed inside the case, and a small explosion from the primer ignites the gunpowder, creating hot gases that push the bullet out of the barrel at a high speed.
Bullets are used by soldiers and police for self-defense, hunting, and shooting targets. Each gun takes a specific size or caliber of bullet, and rifles and handguns use different types. A bullet is not a cartridge but a part of one, consisting of the bullet, case, propellant, and primer.
Is black powder still used in bullets?
Black powder, a mixture of saltpetre, sulfur, and charcoal, was the first explosive used in warfare. When prepared correctly, it burns rapidly when ignited, producing 40 percent gaseous and 60 percent solid products. This gas can be used to propel missiles or artillery shells in confined spaces. Black powder is insensitive to shock and friction and requires flame or heat to ignite. Despite being supplanted by smokeless powder, it is still widely used for ignition charges, primers, fuses, and blank-fire charges in military ammunition. It is also used in fireworks, time fuses, signals, squibs, and spatting charges for practice bombs.
Black powder originated in China, where it was used in fireworks and signals by the 10th century. The Chinese developed the huo qiang, a short-range proto-gun that channeled gunpowder’s explosive power through a bamboo tube. By the late 13th century, the Chinese were employing true guns made of cast brass or iron. Guns began to appear in the West by 1304, when the Arabs produced a bamboo tube reinforced with iron that used a charge of black powder to shoot an arrow.
Black powder was adopted for firearms in Europe from the 14th century but was not used for peaceful purposes until the late 17th century. It remained a useful explosive for breaking up coal and rock deposits until the early 20th century when it was gradually replaced by dynamite for most mining purposes.
How much gunpowder is in a bullet?
It has been demonstrated that gunpowder is not present in bullets, pistol cartridges, or rifle cartridges. A 9mm cartridge contains smokeless power, which is typically a mixture of nitroglycerin and nitrocellulose. However, this substance is not present in the bullet itself. Additionally, no gunpowder is present in any modern cartridge.
What are the ingredients of bullets?

What is the material composition of a bullet?
A bullet is a kinetic projectile used in firearm ammunition, typically made of materials like copper, lead, steel, polymer, rubber, and wax. They are designed for various applications, including hunting, target shooting, training, and combat. Bullets are often tapered for aerodynamic purposes and are measured by weight and diameter in both imperial and metric systems. They do not typically contain explosives but transfer kinetic energy upon impact and penetration.
The term “bullet” comes from the French word “boulle”, meaning “small ball”. Bullets are available individually or packaged with propellant as a cartridge, which includes the bullet, case, propellant, and primer. Cartridges can be held in a magazine or belt for rapid-fire automatic firearms.
The sound of gunfire, known as the “muzzle report”, is often accompanied by a loud bullwhip-like crack as the bullet pierces through the air, creating a sonic boom. Bullet speeds at different stages of flight depend on intrinsic and extrinsic factors. Subsonic cartridges fire bullets slower than sound, resulting in no sonic booms. This means that subsonic cartridges, like the. 45 ACP, can be quieter than supersonic cartridges, such as the. 223 Remington, even without a suppressor.
What is the inside of a bullet made of?
Most pistol bullets are made of lead-antimony alloy encased in a soft brass or copper-plated soft steel jacket. In rifle and machine-gun bullets, a soft core of lead is encased in a harder steel or cupronickel jacket. Armour-piercing bullets have a hardened-steel inner core. Expanding bullets, used in game hunting but outlawed in war, have an exposed soft metal nose that deforms upon impact.
What metal is a 9mm bullet made of?
The projectile, or bullet, is composed of lead coated in a copper jacket. The lead is mined and refined through smelting, a process that converts the extracted ore into a metal.
What does a bullet contain?
Bullets are typically constructed from metal, plastic, or rubber and are commonly utilized for hunting and target shooting. The majority of bullets are manufactured from lead or possess a copper-coated lead core, with inserts crafted from plastic or other materials. Caliber is a term used to quantify the diameter of a bullet’s exterior.
📹 How a bullet works
A lot of effort went into this but there are a couple of gross inaccuracies. Most egregious is, modern cartridges do not use “black power” made of potassium nitrate, sulfur and carbon. They use smokeless powder, which is typically a combination of nitrated compounds(nitro cellulose and nitro glycerin) and additive chemicals that help control the burn rate, fouling, etc. But I do love the animation and narration style. (edited to correct a mistake I made in writing late an night. 🙂
In case anyone is planning to use this article as reference material, it’s worth noting that the bullet & powder weight and velocity specs given are for 9mm Luger cartridges or others very similar to it (common cartridges in use today can fire bullets weighing anywhere from 17 to 400 grains or more, for example).
Your very first line of dialog is incorrect. You are showing a photograph of a Metallic Cartridge. A bullet is one components of a cartridge. The illustration you provide for the powder is not correct either. Powder is made up off small bits that are (generally) either round or tubular. The formula you give, is for Black Powder, which is rarely used today except in reproductions of (mostly) Civil War weapons. The first projectiles were round stones. Later these evolved into lead, and eventually they were clad in copper. Some bullets are made of lead, copper, and steel. Some bullets are 100% lead, some are 100% copper, some are lead coated with copper, and some are made entirely of steel. Some modern military bullets have a steel “penetrator” in their center. There is a huge amount of history involved prior to the modern brass cartridge being developed. Even you title is wrong. At the most you have described the components of a cartridge, although your description of the powder is incorrect both as drawn and described. You should withdraw this and create a correct article describing the components of modern metallic cartridges. The newest cartridges in use are made of both high strength steel and brass. But gun for many years fired bullets that were not encased. They were inserted into a barrel that already had powder in it. Early guns used a burning match to ignite the powder. Nothing in this article describes how bullets work. That is referred to as terminal ballistics.
This article is not totally true The force of the primer, primer, pushes the bullet, and the gun powder out of the casing into the throat of the rifle barrel. This is why the throat, of some barrels are burnt out 1:15 Where the main ignition of the gun powder takes place. The pressure of the burning powder then forces the bullet down the barrel. The length of the barrel, should coincide, with the time the powder stops burning, and creating pressure. When the powder stops burning, there is some residual pressure created At this point, the bullet should be exiting the barrel. A longer barrel is an advantage for sighting, however after the powder has stopped building pressure, the barrel becomes a drag on the bullet. Therefore barrel length, and powder burn should match. My opinion.
The sequencing is wrong. 1 the propellant in the primer, pushes the bullet and the powder out of the shell casing 2 the powder is ignited, when leaving the shell casing. 3 the pressure from the burning powder pushes the bullet out of the barrel of the gun. 4 ideally, the fast burning powder, is totally consumed, as the bullet leaves the barrel of the gun. The fact the primer, pushes, thhe powder out of the casing, and ingniting the powder, at that point, is what burns out the throat of the barrel. Most commercial rifles, have space from the bullet, to the barrel lands. .
Too many mistakes in this article. Downvoted. Powder is wrong. Animation of the start of the burn is wrong. Bullet doesn’t wait for peak-pressure to move. It starts to move (and engrave) earlier than that. Indentation of the firing pin is much more local. You are moving the entire face of the primer-cup.
Firing pin hits primer and pushes whole cartridge to front of headspacing,primer ignites and slides slightly out of cartridge head back against bolt surface,then the powder ignites and cartridge is pushed back to envelope primer again both seating firm on bolt face,and the projectile leaves the cartridge,
