Definitions

  • This invention relates generally to bullets and high-speed methods of manufacturing bullets and, in particular, to jacketed bullets and high-speed methods of manufacturing such bullets.
  • Bullets are made of a variety of materials.
  • Lead or a lead alloy typically containing antimony
  • Traditional bullet jackets are made of copper or gilding metal, an alloy of copper and zinc.
  • copper or gilding metal an alloy of copper and zinc.
  • aluminum, bismuth, bronze, copper, plastics, rubber, steel, tin, and tungsten are many other materials that are used in bullets today, including aluminum, bismuth, bronze, copper, plastics, rubber, steel, tin, and tungsten.
  • Bullet design is dependent on firearm design and vice versa. The bullet must fit into the barrel correctly. A bullet that is too small will not engage the rifling in the barrel, or it will bounce around in the barrel and not exit in a straight line. A bullet that is too large will jam in the barrel, possibly causing the firearm to explode from the pressure. The bullet weight must also match the amount of powder in the cartridge, so that it is fired at the correct speed. [0006] Bullets are designed using calculations and data gathered from previous testing
  • This data can include variables such as accuracy (whether it hit the target), precision (whether more than one of the same bullet type produced similar results), speed of the bullet, effectiveness at a given range (distance to the target), penetration into the target, and damage to the target.
  • Bullets are then tested against a target which resembles what they will be used against. There are several materials used to simulate the intended target, including bullet gelatin, a recently developed material used to simulate flesh.
  • Modern bullets can have many different design features. Some of these features concern the shape of the bullet and others the materials of construction. Most bullets look like a cylinder with a pointed end. The cylindrical section to the rear of the bullet is the shank and the pointed section to the front of the bullet is the tip or nose, though the tip may be flat instead of pointed. Bullets can be made of one or more materials.
  • the shank can have a flat base or a tapered base (boat tail).
  • the flat base is heavier and provides greater penetration, but the boat tail provides greater accuracy over distance.
  • the base of the shank can also have a base plate of harder metal to prevent deformation of the bullet during firing.
  • the base sometimes has a conical indentation (a gas check) that expands on firing to seal the base of the bullet against the firearm barrel and trap all of the energy from firing to propel the bullet forward.
  • the shank may also have grooves used to contain lubricating grease that helps the bullet move freely in the firearm barrel. Sometimes a single groove, called a cannelure, is cut into the bullet to mark how far the bullet is to be inserted into the cartridge and to provide a feature to crimp the cartridge to the bullet.
  • the tip of the bullet is usually pointed. This point may be curved (called an ogive).
  • Wadcutters are bullets with no point or a sharp shoulder behind the point used in target shooting to cut paper targets cleanly.
  • Semiwadcutter bullets have a flat-tipped cone tip and can be used for target shooting, hunting, or self-defense.
  • Target bullets are light and designed for speed and accuracy in a shooting range. They are usually not appropriate for other purposes.
  • tips are designed to expand on impact. This kind of bullet is banned from military use, but can be used for law enforcement, self-defense, and hunting.
  • the tip or the entire bullet may be made of a soft material such as lead, but there are other design features that can aid bullet expansion.
  • Hard material behind the softer tip provides more penetration and pushes the softer tip forward to expand more.
  • the harder material can be the shank, a section of the tip, a partition of hard metal between the tip and the shank, or even a hard point on the tip that is driven backward on impact to expand the softer tip material.
  • Another feature that provides expansion is a hollow tip (or hollow point), an empty cone in the tip that points toward the rear of the bullet.
  • a hollow tip or hollow point
  • the thin sides of the hollow tip expand outward. Even harder metals can expand, especially if they are scored (have grooves cut in them) to provide spaces to split apart.
  • Shotguns often fire shot (many small round pellets) or solid slugs (large, often soft bullets) out of an unrifled barrel, though some shotguns have rifled barrels.
  • Air guns fire solid round or hourglass-shaped pellets.
  • military bullets have special features, sometimes also used in law enforcement and self-defense. In order to get around the prohibition on expanding bullets, military bullets can be designed with heavier than normal back ends so that they tumble into the target on impact to create a larger wound. They can also be designed to break apart on impact with a similar effect. Some military bullets have incendiary (flammable) material in the base of the bullet that leaves a visible trail. This is known as a tracer bullet because it allows the shooter to track the bullet. Incendiary material can also be placed in the tip of the bullet so that it can start a fire on impact. Military bullets are usually made of harder materials or are fully jacketed. They are often designed for penetration. "Non-lethal" plastic or rubber bullets are designed to temporarily incapacitate rioters and demonstrators, but they have the ability to kill.
  • Law enforcement and self-defense bullets should incapacitate the target. Many of these bullets are designed to expand or shatter after hitting the target, causing maximum damage. These bullets can be made of harder material that has greater penetration through materials such as heavy clothing and body armor. Police and self-defense bullets should not "over penetrate” (go through the target) and endanger bystanders.
  • the two most common bullet-forming methods are casting and swaging. Hollow points can be formed by either method.
  • Hard (harder than lead) solid bullets can be stamped (a metal punch cuts a bullet-shaped piece out of a bar or sheet of softer metal) and machined from metal stock. Machining includes any process where a machine is used to shape metal by cutting away portions.
  • a typical machine used for bullets is a lathe. A lathe rotates the bullet metal against steel chisels to gradually cut away material.
  • Casting is pouring molten metal into a mold.
  • This mold is hinged and, when closed, has a hollow space that is in the shape of the bullet.
  • the metal is melted in a crucible (a metal or ceramic pot that can hold molten metal safely) and then poured into the mold.
  • the first material is poured into the mold to partially fill it.
  • the second molten material is poured into the mold to fill it partially or completely. This can be done several times, but most often is done twice to create a bullet with a heavier section (for penetration) behind a softer section (for expansion).
  • Swaging is a cold forming process which means that it involves shaping metal without heating to soften or melt it.
  • the appropriate amount of material to be swaged (measured in grains) is placed in a die.
  • a die is a harder metal container with a cavity (an empty space) shaped like the bullet without the back end.
  • the die is part of a larger stationary object or is held in place on a platform.
  • a metal punch that fits into the open end of the die is forced into the die to the appropriate depth. As the punch forces the bullet metal into the die cavity, the material takes the shape of the cavity.
  • the pressure can come from a manual or hydraulic press, from repeated hammer blows, or from a threaded punch that is screwed on. Excess metal is squeezed out of bleed holes.
  • the punch is removed from the die and the bullet is pushed or pulled out of the cavity. Any imperfections are removed by cutting or filing.
  • Some bullets have jackets of harder metal surrounding a softer core.
  • a coin-shaped piece of jacket metal is punched out of a strip or a sheet.
  • the punch is usually a round metal cylinder that is pushed through the jacket material into a depression in a table. Some punches are rounded so that the piece of metal is shaped like a cup. Sometimes, tubing is used instead of a coin or a cup of metal.
  • the jacket material is too hard to be formed easily, it can be annealed. Annealing is heating the metal, often with a gas flame, to soften it and make it more workable.
  • the jacket material is then placed in a die or over a punch and the punch is forced into the die.
  • punches and dies used to form specific features in the jacket.
  • One of the usual steps is to make sure that jacket is of uniform thickness. The thickness is typically 0.03-0.07 in. (0.08-0.17 cm).
  • Some bullets have a thin jacket electroplated onto the core.
  • Jackets and multiple bullet parts can be joined by method such as swaging them together, casting one section on top of another, soldering, gluing, or electrical welding.
