Definitions

  • the invention relates to a projectile for a firearm. It applies to all calibers of handguns and infantry.
  • Conventional projectiles comprise a core made up entirely or partly of lead and housed inside a metal casing.
  • Heavy metal-free training ammunition is sold by several manufacturers. They make it possible to reduce pollution by residues of the primer. However, these training munitions do not reproduce real shooting conditions because their mass insufficient does not allow to operate the weapon as with service ammunition, which is detrimental to the effectiveness of training.
  • the subject of the invention is a projectile not containing heavy metals, which reduces or eliminates the emission of other metals into the firing zones, and which reproduces the actual firing conditions as with conventional service ammunition.
  • the major advantage of the projectile according to the invention is that it constitutes a non-polishing drive ammunition which keeps the weapon in normal operation and which makes it possible to retain good ballistic properties compatible with standard loads, in particular the maintenance of a reversing impulse, thus ensuring an effective training.
  • An additional advantage is that the projectile according to the invention can be manufactured using existing machines.
  • FIG. 1 shows a section through a conventional projectile.
  • FIG. 2 represents, in section, an example of an embodiment of a projectile according to the invention.
  • a conventional projectile comprises a metal casing 1, made of brass for example, enclosing a core 2 made up wholly or in part of lead.
  • the core it consists of a mixture, amalgam, alloy or other, of at least two materials, for example a ma ⁇ plastic or a light metal, loaded with dust, grains or other, heavier material such as iron.
  • An envelope 12 completely or partially surrounds the core in order to ensure proper functioning in the barrel and sufficient cohesion of the target projectile.
  • the envelope may be metallic (for example in brass) and be secured to the core by any known means, for example by mechanical deformation, electrolytic cage or the like.
  • the envelope may also consist of an organic material charged or not to improve the mechanical properties, and secured to the core by any known means, for example by assembly, spraying, soaking or others.
  • the construction of the envelope must ensure the cohesion of the whole and the proper functioning during the interior ballistic phase (inter alia, taking of the scratches ensuring the rotation of the projectile).
  • a polyethylene core loaded with 50% by volume (i.e. 80% by mass) of iron particles, placed in a brass envelope gives a total mass of the bullet of ⁇ 5 g, which ensures, when it is propelled at a correct and achievable speed, good functioning of the weapons provided for this caliber.
  • This core could be easily produced by extruding a bar, cut into pieces, which are then struck in the envelope.
  • Another production method consists of injecting the amalgam of plastic material - iron directly into the envelope.
