Definitions
- the present invention relates to ammunition for small arms, medium and large calibres, and more particularly advanced ammunition, especially for hunting weapons, having improved efficiency, by a target expansion.
- Shotgun bullets are typically divided between bullet-sized bullets and under-calibrated bullets.
- Conventional bullets in the caliber of the weapon are usually made of lead or lead alloy. They do not fragment and expand only very slightly to the impact on the target. Some involve breakage primers that cause fragmentation of the bullet body on impact.
- These bullets are fired at relatively slow speeds, less than 500 m / s, and are ineffective on medium or strong targets such as large game, such as wild boar.
- the sub-calibrated bullets comprise a sub-projectile, possibly stabilized by empennage, associated with a launch pad, the caliber of the weapon, which separates at the exit of the barrel of the weapon.
- All these conventional balls have drawbacks generally related to their imprecision, their ballistic dispersion and their lack of effectiveness on targets with hard parts.
- So-called expansive bullets, which deform upon impact by mushroom-shaped expansion, including on medium-strength targets, have been described in the art.
- US-A-4,685,397 discloses a ball with ogival body whose head has a blind hole closed by an insert capable of sinking into the hole during impact, and to push outwardly the wall of the ogive.
- Patent EP-A-918,208 describes another embodiment of such a bullet cylindrical body 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.
- PCT application WO 03.093758 discloses an expansion and partial 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.
- the expansive ammunition of this type has the disadvantage of a random control of the deformation according to the shooting conditions, accompanied by a risk of fragmentation of the ogival head of the bullet.
- More advanced ammunition for hunting weapons has been developed on the principle of the arrow bullet. Ammunition of this type are described for example in FR-A-2,555,728.
- FR-A-2,795,170 discloses ammunition that meets this objective, and is essentially constituted by a bullet of the caliber of the weapon or under-calibrated, comprising a profiled front portion, a central portion, and a rear portion being able to carry an empennium, and comprising, disposed along its axis, an internal deflected boom, of rigidity at least equal to that of the body of the bullet.
- the balls of this type are very precise and have the advantage of maintaining their mass during the impact on the target. According to this technique, 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.
- the purpose of the present invention is precisely to optimize the terminal ballistics of a lead-free metal ball of the above type, in order to provide accelerated expansion, while avoiding the loss of mass by fragmentation and by ensuring excellent efficiency on the hard parts possibly present in the target.
- the invention also relates to a hunting weapon ammunition, as mentioned above, providing an accelerated expansion during the impact on the target, in particular on a low or medium resistance target.
- the subject of the invention is also an ammunition for hunting weapons with improved terminal efficiency on medium or low resistance target, constituted by a cartridge, consisting of a primed sleeve, a powder charge propulsive, and a complete ball, if any associated with a launcher the 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, avoiding any fragmentation of the bullet on impact.
- the present invention is applicable to ammunition of small, medium or large caliber, the type of the caliber of the weapon or sub-calibrated, for hunting weapons with smooth or striped barrel.
- the ammunition for small, medium and large weapons, according to the present invention is constituted by a bullet of the caliber of the weapon, or sub-calibrated, of the type comprising a substantially rigid body of ball and a deformable part, and it is distinguished in that the deformable portion is constituted by a substantially cylindrical expansion ring whose rear portion is mounted on the front portion of the bullet body.
- the cylindrical expansion ring is fixed by its rear part on the bullet body, and the attachment may be advantageously detachable from the bullet body.
- the expansion ring comprises means cooperating with the bullet body to prevent its recoil during impact on the target so that the energy released on impact is partly absorbed by the deformation of the target. the ring.
- These means may be constituted by a stop secured to the rear portion of the ring, bearing on a shoulder on the bullet body. It may be advantageous to provide that the bale body has a shoulder against which abuts the rear face of the cylindrical ring.
- the expansion ring comprises on its front face an opening frustoconical bore, cooperating with the front face of the head of the bale body to form an open cavity.
- the volume and the opening angle of this cavity are determined according to the desired results, in application of as for conventional calculation methods to achieve the maximum stopping power on the target, by effect of dilation, penetration and hydrodynamic cavitation.
- the frustoconical bore opening on the front face of the expansion ring is designed to form with the outer cylindrical portion of the ring, a flat or a narrow expansion lip, which facilitates the movement of the ring. expansion of the ring at impact on the target.
- the base of the frustoconical bore is designed to form with the outer cylindrical portion of the ring, a flat or a narrow expansion lip, which facilitates the movement of the ring. expansion of the ring at impact on the target.
- opening comprises an annular bearing bearing against the cylindrical surface of the ball body head and slidable on it.
- This annular bearing is separated from the rear part of the cylindrical ring by an annular groove.
- the annular bearing ensures a deformation by regular expansion of the ring by preventing misalignment with respect to the axis of the ball. It also maintains the ring from all angles of fire, including tangential shots generating significant radial forces. Finally, it contributes to the good grip of the ball in the case of an impact on the ground by maintaining the ring in the axis of the bullet body, and thereby decreases the propensity to lateral ricochets of the ball, and thus increases shooting safety.
- the outer surface of the expansion ring is generally cylindrical, but it may be slightly curved and have a low taper, especially in the case of caliber bullet. According to a preferred embodiment, the outer surface of the cylindrical ring has a curvilinear ogival shape.
- the front face of the expansion ring is substantially in the plane of the face of the ball body head. However, depending on the desired effect, it can be protruding, which reduces the aerodynamic drag, or conversely slightly recessed.
- the bullet body comprises a front part supporting the expansion ring, of cylindrical shape ending in a conical or frustoconical tip. This part constitutes an arrow intended to fragment the hard parts possibly present in the target.
- the terms “front part” and “rear part” used herein respectively denote the front or back of the ball, in the direction of the shot.
- the arrow corresponds substantially to the front part of the bullet body.
- the body of the bale may be for example copper, preferably copper heat-treated or mechanically to increase its hardness and rigidity, or brass containing 5 to 40% zinc and 95 to 60% copper, preferably brass containing 20 to 30% zinc, or metal alloy having the desired mechanical properties, for example aluminum alloy, or 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 made of metal or polymer formed by plastics directly on the metallic body of the subprojectile.
- the bullet body used in the ammunition of the invention advantageously comprises a front part comprising an arrow of revolution.
- the bullet body and the arrow are preferably made of the same material, for example copper or brass, the arrow being machined directly on the bullet body.
- the arrow usually has the shape of a rod or a cone of revolution, coaxial with the projectile. It is advantageous to provide ribs or bearings on the outer surface of the boom to improve attachment of the expansion ring. It may be for example annular or helical ribs, cooperating with means provided on the inner face of the ring.
- the expansion ring is attached to the bullet body by screwing, by friction welding or by hooping, or by force fitting, for example by means of a contact surface knurled in diamond points.
- the expansion ring is preferably made of metal or metal alloy, for example brass, of lower or equal rigidity, and preferably lower than that of the bullet body. This difference in stiffness between the bullet body and the expansion ring can be obtained for example by choosing brasses with an appropriate zinc content. Breaking primers may be provided on the expansion ring.
- breaking primers cooperating with the more rigid boom, promote deformation of the head of the bullet during the impact by "mushrooming" around the central deflector which retains its general shape and serves as a structure ensuring the cohesion of the 'together.
- 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 gyro-stabilized bullet is used in a rifled barrel, so that the stripe 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 launch pad in the case of a sub-calibrated bullet, may be in accordance with those described in patents FR-A-2,606,500 and FR-A-2,708,730.
- the ammunition of the present invention can be used on relatively hard and high strength targets, as well as soft targets of low strength on which they provide excellent terminal efficiency. This excellent efficiency results in particular from the effect of controlled expansion on impact, after perforation of the hard and resistant parts possibly present in the target. 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-2,795,177 cited above, even at considerable distances, of the order of 300 m and more in the case of gyro-stabilized bullets.
- FIG. 1 The point of impact is then identical to that of the above-mentioned approach booms with the aerodynamic parameters and the construction of the ball in flight order.
- firing safety is ensured from all angles of fire on the target, including tangential angles through the open cavity formed on the front of the bullet, combined with the relatively small diameter of the tip of the ogival head. , thus limiting the propensity for ricochets.
- the ammunition of the invention is therefore particularly suitable for hunting small or medium game, but may also be suitable for large game with relatively thick and resistant skin.
