Definitions

  • the present invention relates to ammunition for small arms, medium and large calibres, and more particularly advanced bullet bullet ammunition, particularly for hunting weapons, having improved efficiency, by a delayed expansion on target.
  • Bullet ammunition has been known in the art for many years. They comprise a subprojectile, or arrow, stabilized by empennage, associated with a shoe, or launcher, the caliber of the weapon, so that the launcher surrounds at least partially the arrow, the arrow-launcher assembly being placed in a crimped cartridge, which further comprises a primed sleeve and a propellant charge. Ammunition of this type is described for example in the patent FR-A-2555728 .
  • the arrow In the field of hunting weapons, during the impact of ammunition of the arrow bullet type on the target, the arrow is deformed, and it is desirable that this deformation be controlled and does not provide too much dislocation of the arrow in several small fragments that could be dangerous.
  • the patent FR-A-2795170 describes ammunition that meets this objective, and essentially consists of a bullet of the caliber of the weapon or under-calibrated, comprising a profiled front portion, a central portion, and a rear portion that can carry an empenne, and comprising, arranged along its axis, an internal arrow carried, of rigidity at least equal to that of the body of the ball.
  • the balls of this type are very precise and have the advantage of maintaining their mass during the impact on the target.
  • the diameter of the nose of the warhead is between 40 and 50% of the maximum diameter of the bullet, which gives it a significant aerodynamic drag.
  • These bullets are therefore mainly intended for so-called "beat" firing, at short and medium distances, less than 150 m for rifles, and of the order of 50 to 60 m for shotguns.
  • Conventional lead-core bullets are mainly used on low-resistance targets and are ineffective on medium or high-strength targets.
  • So-called expansive bullets are also known, which have the characteristic of being deformed on impact by a mushroom-shaped expansion, including on medium-strength targets.
  • the patent US Patent 4,685,397 describes a bullet with an ogival body whose head comprises a blind hole closed by an insert capable of sinking into the hole during impact, and to push outwardly the wall of the nose.
  • the patent EP-A-918208 discloses another embodiment of such a cylindrical body bullet and ogival head having a blind hole along its axis, closed by an insert, supplemented by a peripheral annular groove.
  • the insert sinks into the blind hole and then causes deformation by expansion of the ogival head, which is facilitated by the annular groove.
  • Requirement PCT WO 03.093758 discloses a partial expansion and fragmentation ball having an orifice located in the head of the warhead, completely closed by a plug mounted on a rod, the movement of which causes deformation of the body of the bullet.
  • Requirement WO 0120245 describes another example of bullet whose ogival head has a hole closed by an insert.
  • Another example of a monobloc expansive ball is described in the patent application WO 97.40334 .
  • a variant of a delayed-expansion hunting bullet is described in the patent EP-A-1394498 according to which the bullet body is completely traversed by an element which, on impact, causes deformation of the bullet body.
  • the present invention relates to bullet-type ammunition providing excellent target efficiency, and more particularly relates to ammunition for hunting weapons capable of preventing the formation of multiple fragments and ensuring the destruction of the hard parts of said target, delaying expansion to release energy into the most vulnerable part of the target, especially on hard targets and strong resistance.
  • the subject of the present invention is therefore a small, medium or large caliber ammunition ammunition of the type with an internal deflected boom, providing a controlled expansion upon impact on the target.
  • the invention also relates to a hunting weapon ammunition, as mentioned above, providing a delayed expansion upon impact on the target, in particular on a hard-shelled and hard-shelled target, without decreasing the efficiency on low and medium resistance targets.
  • the subject of the invention is also an ammunition for hunting weapons with improved terminal efficiency on a hard and resistant target, in particular for big game, constituted by a cartridge, consisting of a primed sleeve, a charge of propellant powder, and a complete ball including an internal arrow carried, if any associated with a launcher caliber of the weapon.
  • the invention finally relates to a lead-free ammunition for hunting weapons having an optimized terminal ballistics, providing an almost total release of energy in the soft parts of the target after perforation of the hard part, avoiding any fragmentation of the bullet on impact.
  • the ammunition for small arms, medium and large calibres is constituted by a bullet of the caliber of the weapon or under-calibrated, of the type comprising a bullet body comprising an ogival head and able to carry a stamina, and an internal deflected spear inserted in an axial hole, the rigidity of the spire being greater than or equal to that of the body of the ball, and it is distinguished in that the inner spire is arranged protruding from the face before the bullet body, can slide at impact on the target, and passes through an open conical cavity formed in the front face of the ogival head.
  • this conical cavity with an expansion lip formed at the junction of the conical cavity and the end face of the ogival head. It is advantageous that this open conical cavity has a shape such that the angle of its generatrix with the axis of the arrow is between 10 and 50 °. According to a characteristic of the invention, the section of the internal arrow is less than or equal, over its entire length, to the diameter of the axial hole. Thus, the sliding of the internal arrow does not directly cause any deformation of the bullet body.
  • the axial hole in which the internal arrow is inserted is preferably a blind hole, of depth generally between 30 and 80% of the height of the bullet body.
  • the sliding of the internal arrow which causes the effect of delayed expansion at impact, is obtained by providing a suitable space between the base of the internal arrow and the bottom of the axial hole in which it is inserted, this corresponding space. at a free distance along the axis which is greater than or equal to the sliding distance of the internal arrow.
  • This distance is set according to the desired effect and the conditions for shooting. It is preferably at least equal to the length of the arrow projecting from the front face of the body of the ball. According to a preferred embodiment of the invention, this free distance, available for the sliding of the boom, is between 0.2 and 1.5 times the total length of the internal boom.
  • the internal arrow protrudes from the frontal face of the head ogival ball on a length generally between 2 and 7 mm.
  • the head of the internal arrow first hits the target and then slid into the body of the bullet at the same time as it enters the target.
  • the hydrodynamic pressure generated by the penetration of the head of the internal arrow in the target is practiced practically only on the front face of the internal boom, then, when the latter sinks into the body of the ball, the distance of protrusion of the internal arrow decreases, until the hydrodynamic pressure is also exerted on the front face of the head of the ball.
  • the open conical cavity formed on the ogival head and the expansion lip combine their effects to initiate the deformation by expansion of the ogival head and amplify it at the same time as the bullet enters the target, thereby creating a large hydrodynamic cavity in the most vulnerable part of the target.
  • the internal arrow is constituted by at least two consecutive elements arranged contiguously on the same axis. According to a variant according to the present invention, it consists of at least two consecutive elements arranged on the same axis and separated by a gap.
  • This limiter may be constituted by a decrease in the diameter of the rear portion of the hole receiving the arrow, thus forming a shoulder against which the internal arrow abuts when it slides during the impact on the target.
  • it is constituted by a second arrow placed at the bottom of the hole receiving the two arrows.
  • the inner boom has frustoconical ends.
  • the frustoconical shape of the front end facilitates the beginning of the expansion movement of the ogival head.
  • This frustoconical shape cooperates with the open frustoconical cavity surrounding the internal deflection and makes it possible to reduce the hydrodynamic pressure created during the penetration of the arrow into the target and thus to reduce the length of the hydrodynamic channel formed.
  • the front and rear ends of the boom have the same frustoconical shape, which simplifies the manufacture of the ammunition.
  • the hunting bullet of the invention is clearly distinguishable from expansion bullets such as those described in the patents EP-A-918208 and US Patent 4,685,397 where the insert serves to close the axial cavity made in the head of the warhead and deform it by simple displacement on impact, while the internal boom used in the invention is designed to cause a delayed expansion and does not directly cause deformation of the ogival head of the bullet body.
  • the internal arrow may be made of a single element or of several consecutive elements arranged on the same axis, contiguously or separately. It may be advantageous, for example, to provide an internal arrow in two elements.
  • the internal deflection may be of the controlled fragmentation type and may comprise elements that disperse on impact, for example balls of diameter substantially equal to that of the internal deflection. This embodiment makes it possible to obtain splinters calibrated during the impact, and thus improve the lethal power of ammunition by creating secondary injuries.
  • the internal boom can be made for example of steel, titanium, copper, brass or aluminum alloy with high mechanical strength, or technical plastic such as ABS, very high rigidity.
  • the body of the bullet may be for example copper, or brass containing 5 to 40% zinc and 95 to 60% copper, or metal alloy having the desired mechanical properties, for example aluminum alloy or aluminum. composite material based on tungsten or bismuth.
  • the technique of the invention has the advantage of allowing the lead to be completely or partially replaced by another metal or alloy known to be non-polluting.
  • the empennage may be metal or polymer formed by plastics directly on the metal body of the sub-projectile.
  • the internal arrow and the bullet body used in the munitions of the invention may be made of the same material, for example copper or brass.
  • the rigidity of the internal arrow is equal to that of the body of the ball.
  • the internal arrow is made of a material of greater rigidity than the bullet body, and the ammunition is then of the bimetallic or monometallic type with differentiated rigidity between the bullet body and the arrow.
  • the internal arrow is generally in the form of a rod of revolution with a constant section, coaxial with the projectile. It may be advantageous to provide ribs on the cylindrical surface to improve the attachment of the internal arrow in the body of the ball. They may be annular or helical ribs, or, preferably, longitudinal ribs, 2 to 6 in a part or the entire length of the cylinder, symmetrically with respect to the axis. In addition, the longitudinal ribs can be used to form fracture primers on the front face of the bale when the boom is placed. internal cylindrical force introduction into the hole previously drilled along the axis of the ball. If the bale is obtained by cold deformation, the internal deflected boom, previously placed in the axis of the bale blank, will print its longitudinal ribs in the material of the discharged body by means of a press and will thus create the primers desired breaks.
  • breaking primers cooperating with the internal deflection, promote the deformation of the head of the bullet during the impact by "petalization” or “muscular” in as many elements as ribs, around the central internal arrow which retains its general shape and serves as a structure ensuring the cohesion of the whole.
  • They can be associated in combination with circular or longitudinal grooves made around the bead, preferably in the zone deforming by expansion, whose deformation must be controlled.
  • the ball may be of the gyroscopic stabilization or empennage type.
  • the gyrostabilized bullet is used in a rifled barrel, so that the scratch of the barrel, cooperating with a tenon integral with the bullet, gives it a rotational movement along its axis.
  • Stabilized bullets can be used in smooth-bore weapons.
  • the ammunition according to the present invention can be used on very hard and very strong targets, on which they provide excellent terminal efficiency, without diminishing their effectiveness on low or medium resistance targets.
  • This excellent efficiency results in particular from the effect of delayed expansion at impact, after perforation of the hard and resistant parts of the target by the internal arrow. It is obtained while maintaining the aerodynamic parameters of the approach bales with an internal arrow carried using the technique described in the patent FR-A-2795170 aforementioned, even at significant distances, of the order of 300 m and more.
  • the point of impact is then identical to that of approach bales at internal arrows range above thanks to the aerodynamic parameters and the construction of the ball in flight order.
  • the delayed expansion is provided from all angles of fire on the target, including tangential angles through the open cavity of the forward portion of the bullet, combined with the relatively small diameter of the inner boom.
  • the ammunition of the invention is therefore particularly suitable for hunting large game with thick skin or shell hard and resistant, for example some large African game, especially the buffalo.
  • the caliber ball (1) comprises a bullet body (2) and an internal arrow (3).
  • the ball body (2) is monobloc and comprises at its front part an ogival head (4), at its central part a bullet body (5) and at its rear part a narrowing of the base (6).

  • the whole of the bullet and the internal arrow is partially introduced into a case carrying a primer and a propellant charge, of conventional type, not shown.
