Definitions

  • This invention relates to improved training ammunition and to a method of modifying a gun to fire the training ammunition.
  • Training cartridges are characterised in that they impart much less energy to a projectile than a live (“killing”) round.
  • a live round may impart 800 ft/lbs of energy to a bullet and a shotgun may impart as much as 1000 ft/lbs of energy to the shot
  • training cartridges are much less energetic.
  • the energy imparted to a projectile by a training cartridge is typically less than 5 ft/lbs and more usually less than 4 ft/lbs.
  • the term “training cartridges” as used herein therefore refers to such low energy cartridges, unless the context indicates otherwise.
  • the aforementioned training cartridges typically contain only a primer and do not contain a conventional amount of propellant. Consequently, they must be carefully designed to ensure that there is sufficient energy both to recycle a weapon and eject a projectile such as a bullet.
  • Many training cartridges see for example the cartridges disclosed in the patent documents supra, are of the expanding type in which the body of the cartridge comprises a “piston and cylinder ” arrangement. With such cartridges, part of the energy of the primer is used to force the piston and cylinder apart (i.e. expand the cartridge) and drive the rear end of the cartridge back to recycle the weapon, and part of the energy is used to discharge the projectile from the front end of the cartridge. Careful control of gas flow within the cartridge is required in order to make sure that the projectile is discharged at a consistent and appropriate velocity and that the weapon is recycled at every firing.
  • FIG. 1 shows a sectional elevation through the primer for a centre fire cartridge of the type typically used in live military ammunition.
  • the primer comprises a can 2 formed from, for example, nickel plated brass, and containing a suitable pyrotechnic primer material 4 .
  • the can is held in a recess in the centre of the rear surface (not shown) of the cartridge.
  • An anvil 6 is set into the front of the can 2 to close the can and retain the primer in place. As the anvil is inserted into the can, the protruding central part 6 a of the anvil greatly compresses the primer to create a compressed region 4 a which is highly sensitive to shock.
  • the region 4 a which is sensitive to shock has an approximate width I, and this represents the impact area for the firing pin of a centre fire weapon.
  • a centre fire firing pin will impact against the impact area and further compress the primer between the wall of the can and the anvil thereby detonating the primer.
  • the firing pin of a rimfire weapon would impact against the can outside the impact area I and hence would not detonate the primer.
  • the present invention makes use of peripheral fire primers in the training cartridges, and a gun modification which allows the firing pin of the gun to strike the periphery (i.e. rim) of the primer which fires a cartridge. If any type of centre fire cartridge is fitted into the gun whilst the conversion is fitted, the firing pin cannot set off the centre fire primer as the point of impact of the firing pin is beyond the sensitive part of the centre fire primer. Thus, the present invention prevents the standard centre fire military ammunition from being fired inadvertently instead of low velocity training ammunition.
  • the invention provides a training cartridge having a peripheral fire primer.
  • the primer typically takes the form of a cup or “can” which is set into the rear end of the cartridge.
  • the cup typically has a hollow peripheral rim in which the primer material is located, the primer material being in a compressed state and highly sensitive to shock.
  • the primer material can thus be detonated when the peripheral rim of the can is impacted by a firing pin.
  • This arrangement is in contrast to conventional live rimfire cartridges ( i.e. 0.22 ′′ calibre) in which the primer material is located in the rim of the cartridge itself rather than the peripheral rim of a cup set into the rear of the cartridge.
  • the training cartridges of the invention are preferably expandable upon firing, expansion of the cartridge serving to urge a rear surface of the cartridge rearwardly against a breech block of a gun to initiate recycling of the gun.
  • an expandable training cartridge configured to enable a projectile (e.g. a bullet) to be mounted in or on a nose portion thereof, a gas passage though the nose portion providing communication between the cartridge interior and the projectile.
  • the cartridge has valve means for controlling propellant gas flow through the gas passage to the projectile, and a movable member which upon firing is propelled rearwardly from the cartridge against a breech block of the firearm by the pressure of propellant gas within the cartridge so as to recycle the firearm.
  • the valve means is preferably arranged to close in order to stop or substantially reduce the flow of propellant gas through the said gas passage after the projectile has been fired from the cartridge, thereby to facilitate rearwards propulsion of the movable member.
  • the training cartridge can be of the general type described in any one of PCT98/00620, PCT/GB99/02859, PCT/GB99/02556 and GB 9819928.4, but with an appropriately modified primer.
  • the diameter of the training cartridge is generally greater than the diameter (usually approximately 0.375′′ (9 mm)) of live 0.22′′ (5.65 mm) rounds although the training cartridge may carry a 0.22′′ (5.65 mm) bullet or projectile, and may be provided with a primer of a diameter typically associated with a 0.22′′ (5.65 mm) round.
  • the primer is the only pyrotechnic material in the cartridge; i.e. there is no propellant other than the primer.
  • the primer is such that the cartridge produces an energy of less than 4 ft/lbs, more preferably less than 3 ft/lbs, for example less than 2.5 ft/lbs, and most preferably 2 ft/lbs or less.
  • the invention provides a method of modifying a gun to prevent it from firing live ammunition but permit the firing of a rimfire primer training cartridge, which method comprises (i) replacing a centre fire firing pin with a rim fire firing pin and/or (ii) replacing a barrel of the gun such that a centre firing pin is misaligned for centre firing of the cartridge but is aligned for rim firing of the cartridge, but excluding the modification of a gun capable of firing live 0.22′′ (5.56mm) cartridges by replacing the centre firing pin with a rimfire firing pin.
  • the invention provides a method of modifying a gun to prevent it from firing live ammunition but permit the firing of a rimfire primer training cartridge other than a 0.22′′ (5.56 mm) calibre cartridge, which method comprises replacing a centre fire firing pin with a rim fire firing pin.
  • the invention provides the combination of a training cartridge having a rimfire primer and a gun that has been modified to fire a rimfire primer-containing training cartridge.
  • the invention provides a peripheral fire primer for use in a cartridge as hereinbefore defined, the primer comprising a cup for setting into the rear end of the cartridge, the cup having a hollow peripheral rim containing compressed primer material.
  • the invention provides a method of modifying a gun to prevent it from firing live ammunition but permit the firing of a rimfire primer training cartridge, which method comprises selecting a gun having a centre fire firing pin and replacing the barrel of the gun with a barrel in which the breech is offset such that the centre fire firing pin can impact against and fire the rimfire primer training cartridge but not a centre fire cartridge.
  • the invention provides a gun having a centre fire firing pin and a barrel in which the breech is offset such that the centre fire firing pin can impact against and fire a rimfire primer cartridge but not a centre fire primer cartridge.
  • the centre fire firing pin of a gun prior to modification is arranged such that it strikes at a location which is central with regard to the bore or breech of the barrel, i.e. the centre line of the firing pin is coincident with the centre line of the barrel.
  • the centre line of the bore of the barrel is offset relative to the centre line of the firing pin.
  • a further advantage of the offset of the bore is that the bore can be inclined with respect to the axis of the barrel thereby providing a means of correcting the trajectory of the low velocity projectile without the user of the gun needing to make any changes to his normal sighting.
  • the centre line of the firing pin may still be aligned with the centre line of the bore of the barrel but the modified pin typically has a laterally extended leading end portion, the laterally extended leading end portion having a leading surface profiled such that it impacts against the rim of a rimfire primer but not against the centre of a centre fire primer.
  • the laterally extended leading end portion can be laterally extended in one plane or in two planes.
  • the end of the pin when it is extended in one plane, can take the form of a flat spade-like structure that slides in a slot cut into the breech block.
  • the flat spade-like structure may have one or two (and preferably two for balance) forwardly oriented projections at the edges thereof for impacting against the rim of a rimfire primer but not the central impact area of a centre fire primer.
  • the leading end portion of the modified firing pin When the leading end portion of the modified firing pin is laterally extended in two planes, it can, for example, have a cylindrical form.
  • the leading surface can have one or more (preferably more than one) discrete projections protruding forwardly therefrom, or the leading surface can be provided with a forwardly projecting annular rim having a diameter such that it impacts against the impact area of a rimfire primer but not the impact area of a centre fire primer.
  • the region of the leading surface between or inwardly of the projection(s) can be cut away, at least over the area that would overlap with the impact area of a centre fire primer.
  • FIGS. 1 to 9 The invention will now be illustrated, but not limited, by reference to the particular embodiments shown in the accompanying schematic drawings, FIGS. 1 to 9 .
  • FIG. 1 is a side sectional elevation through a centre fire primer.
  • FIG. 2 is a side sectional elevation through a rimfire primer.
  • FIG. 3 is a schematic elevation of a conventional arrangement of a centre fire primer in a gun fitted with a centre fire firing pin.
  • FIG. 4 is a schematic elevation of a conventional arrangement of a rimfire primer in a gun fitted with a rimfire firing pin.
  • FIG. 5 illustrates schematically part of a standard centre fire pistol having a barrel containing a centre fire primer cartridge.
  • FIG. 6 illustrates schematically the centre fire gun of FIG. 5 but wherein the barrel has been replaced by a modified barrel.
  • FIG. 7 illustrates a standard rifle fitted with a centre fire firing pin and containing a centre fire primer cartridge.
  • FIG. 8 illustrates the rifle of FIG. 7 but with a modified firing pin.
  • FIG. 9 illustrates an explosive blank cartridge having a peripheral fire primer.
  • a peripheral fire primer for use in a cartridge according to the invention is shown in FIG. 2 and comprises a can 102 , the closed end of which is formed to provide a hollow peripheral rim area 103 .
  • a pyrotechnic primer composition 104 is placed in the can and the can is spun thereby forcing the pyrotechnic material into the hollow peripheral rim area 103 .
  • the impact area I′ is annular in shape and extends around the peripheral rim of the primer.
  • FIGS. 1 and 2 together there will be a dead zone S between the impact region I of a centre fire primer, and the impact region I′ of a peripheral fire region in which any impact will not detonate the primer.
  • the firing pin strikes impact area I′ and compresses the pyrotechnic composition between the two walls 103 a and 103 b of the hollow rim region 103 , the shock imparted to the pyrotechnic composition causing it to detonate.
  • FIG. 3 there is shown a conventional arrangement of a gun 200 having a centre firing pin 202 , a training cartridge 204 being inserted into the breech thereof.
  • the cartridge 204 has a centre fire primer 206 fitted into the end thereof, the primer being of the type shown in FIG. 1. It will be noticed that the centre line L 1 of the firing pin 202 is coincident with the centre line L 2 of the barrel of the gun.
  • FIG. 4 there is shown an arrangement in which a gun 300 has been modified to provide it with a peripheral fire firing pin 302 which is offset from the centre line of the barrel so that it can fire a training cartridge 304 having a peripheral fire primer 306 of the type shown in FIG. 2.
  • the invention provides a training cartridge which is detonated by impact on the peripheral rim of the primer, and makes use of a gun which is specially modified to allow use of the peripheral fire primer.
  • FIG. 5 shows a standard centre fire pistol into which has been inserted a cartridge having a centre fire primer.
  • the arrangement shown in this Figure corresponds to FIG. 3 except that the barrel of the pistol is removable.
  • FIG. 6 shows a modification of the gun shown in FIG. 5.
  • the gun is still provided with a centre fire firing pin 410 which, with a normal gun barrel, would allow the firing of centre fire cartridges.
  • the gun is converted by replacing the normal gun barrel with a gun barrel 412 in which the bore 414 is offset.
  • the bore 414 is inclined at an angle a with regard to the axis 16 of the barrel.
  • the centre line of the bore 414 is also inclined with respect to the centre line of the firing pin 410 .
  • the relative geometry of the gun barrel and firing pin are such that the firing pin can fire the cartridge.
  • a centre fire cartridge for example a live killing cartridge
  • the firing pin 410 will fail to strike the centre fire impact area 318 , and hence the cartridge will not detonate.
  • the modification of the invention greatly enhances the safety in that it prevents live killing ammunition from being inadvertently mixed with training ammunition.
  • a further advantage of the arrangement shown in FIG. 6 is that it can enable training ammunition to be used more accurately.
  • One of the problems with training ammunition is that the low velocity means that the bullet will often fall away before it reaches a target, and consequently there will be a tendency for the user to compensate for this by aiming above the target. Thus shooting at targets using low velocity ammunition can be less realistic than is desirable.
  • the user of the gun can fix his sights on the target in the normal way, and the angle of the bore, rather than the angle of the barrel, provides the necessary correction to enable the projectile to reach its target.
  • the range of the training ammunition is much closer to the range of normal live killing ammunition.
  • FIG. 6 The modification shown in FIG. 6 is particularly suited to pistols since in many cases the barrel of a pistol can be removed fairly easily. However, the barrels of rifles are typically fixed and hence a barrel modification of the type shown in FIG. 6 would involve somewhat more complex alterations to the gun and would not be a practical proposition.
  • FIG. 7 shows a part of a conventional rifle equipped with a centre firing pin and having a centre fire training bullet inserted in the breech thereof.
  • FIG. 8 illustrates the same rifle but wherein the firing pin has been modified.
  • the firing pin is no longer pin-shaped but instead has a leading end which is extended laterally to give a spade-like shape.
  • the leading surface of the leading end has forwardly oriented projections 512 at either edge thereof, the projections being aligned with the impact region 514 of the peripheral fire primer 513 of the cartridge.
  • the central part 516 of the leading end is recessed, the width of the recess being at least as great as the width of the impact area of the centre fire primer 318 .
  • the projections 512 on the edges of the leading end of the modified firing pin impact against the sensitive impact region of the peripheral fire primer to detonate the primer.
  • a cartridge e.g. a live killing round
  • centre fire primer is inadvertently inserted into the gun, it will not be detonated.
  • the safety of the modified firing pin arrangement shown in FIG. 8 is further enhanced by virtue of the recessed central region 516 which ensures that centre fire primers cannot accidentally be detonated as a result of the presence of particles of debris between the firing pin and cartridge.
  • the modified firing pin of FIG. 8 can be fitted, for example, by shortening an existing firing pin, cutting a thread on the end thereof, and fixing the threaded end into a suitably profiled end piece.
  • the circular channel or opening in which the firing pin normally slides is machined out to form a slot to accommodate the spade-like shape of the end piece.
  • FIG. 9 illustrates an explosive blank cartridge that can be fired in the modified gun of FIG. 8.
  • the blank cartridge comprises a casing 602 closed at its nose 604 and containing an explosive material 606 .
  • the rear end of the blank cartridge has a flange 608 to enable the spent cartridge to be extracted from the breech in the usual manner.
  • the blank cartridge is of conventional construction.
  • the cartridge differs from conventional blank cartridges in that the primer 610 set into the centre of the rear of the cartridge is a peripheral fire primer.
  • the primer 610 which can be of the form shown in FIG. 2 or an appropriate modification thereof, comprises a cup or can 612 having a hollow peripheral rim 614 containing compressed primer material.
  • the off centre firing pin 616 of the gun impacts against the peripheral rim 614 thereby detonating the primer material which in turn detonates the explosive material 606 . Expanding gases created by the detonation of the primer and explosive material burst through the nose 604 in the usual manner to give a realistic bang.
