Sports floor for a sports cartridge in particular for dynamic IPSC shooting, wherein the sports floor is designed as a preferably encapsulated solid wall particularly with lead core and / or copper sheath and a cylindrical guide portion for holding the sports projectile in a propellant charge shell of the sports cartridge and for guiding the sports projectile in a barrel of a sports weapon and a front portion having a tapered end portion, wherein it is provided that the guide portion is offset relative to the front portion in the radial direction to the outside.

Description

The invention relates to a sports bullet for a sports cartridge and a sports bullet with a sports bullet, which is particularly suitable for use in the context of dynamic sports shooting or IPSC shooting (International Practical Shooting Confederation) and at the same time, the regulatory requirements of the Standing International Commission for Examination from Arms à Feu Portatives (CIP; Commission Internationale Permanente pour l 'Epreuve des Armes à Feu Portatives).

In dynamic IPSC shooting, a sportsman moves with loaded, firearm gun under time pressure within a course. After a start signal, the marksman crosses the course and has to hit several different targets as precisely as possible within the shortest possible time. The competition score of the shooter is calculated on the basis of the hit quality and speed and is called a hit factor. As a target medium in particular as "IPSC target" designated cardboard discs with subdivided into several hit areas areas are used. In the weighting of the hit quality, the sports floor used by the shooter is taken into account, whereby a so-called "major factor" or "minor factor" is used. The subdivision to major or minor depends on a power factor score of the used sports weapon and ammunition. The power factor score is calculated from the bullet weight in grains (1 grain = 0.0648 g) and the bullet velocity in feet per second (1 feet per second (fps) = 0.3048 meters per second (m / s)), where the power factor score is calculated as bullet weight times bullet speed divided by 1,000 and then rounding off. For the according to the type of weapon divided into so-called divisions shooters depending on the type of weapon different factor score minimum limits, on which it depends whether the shooter the major factor or the minor factor is awarded, or if the shooter falls below the minimum threshold minors can only participate in a competition without being considered. To determine the power factor score of the sporting gun of the sports shooter is determined with a precise balance of the weight of a sports projectile and the average bullet speed of several, preferably three, shot over a chronograph sports cartridges calculated according to the IPSC rules of the Federal German sports marksmen e. V. (version of the BVA approval decision of 19 June 2015, editorial status 18 August 2015) applies, for example, to the IPSC short-shootings: Open Division pistol Standard Division pistol Classic Division pistol Product Division pistol Revolver Division Major power factor (min) 160 170 170 - 170 Minor Power Factor (min) 125 125 125 125 125 Minimum bullet weight 120 grain (for Major) - No - Minimum bullet caliber 9 mm (.354 '') Minimum sleeve length 19 mm (.748 '') Minimal floor caliber for major - 10 mm (.40 '') 10 mm (.40 '') - - Table 1: Excerpt of the BDS rules for IPSC handgun shooting

Injured by IPSC specifications is armor piercing ammunition, firearms, tracer ammunition and ammunition that shoots more than a single bullet from a single cartridge. In addition to the handguns exemplified here, dynamic IPSC sport shooting can also be carried out with rifles, shotguns, etc. In general, the IPSC rules set relatively high ballistic performance requirements for sports cartridges to meet the minimum power threshold (Minor) required for competition, and very high performance requirements for sports cartridges to achieve major classification.

In addition, all cartridges, including sports cartridges, must comply with safety requirements or regulatory requirements, such as laws. For the European countries in particular the CIP specifications apply, which on the one hand make caliber-dependent cartridge and projectile geometry specifications, in particular with regard to the cartridge case length, the overall projectile length as well as with regard to the train profile and the field profile of the barrel. Furthermore, the CIP regulations set a maximum allowable gas pressure that may occur during the firing of a cartridge in the course of the firearm. For example for cartridges of the caliber 9 mm Luger (also known as 9 mm Para, 9 mm Parabellum, 9 × 19 mm) according to the CIP specification with date 84-06-14, revision 08-09-23 for a CIP measuring run with 150 mm length a mean maximum gas pressure of 2,350 bar. Comparable safety regulations, for example for the USA, follow from the guidelines of the SAAMI (Sporting Arms and Ammunition Manufacturers' Institute).

As a result of the conflict between the high ballistic performance demanded by the IPSC rule on the one hand and limits in particular with regard to the maximum permissible gas pressure as a result of regulatory requirements, for example according to CIP, the development of a sports projectile or sports cartridge, in particular for use in IPSC sport shooting, is subject to high technical standards challenges.

It is an object of the invention to provide a sports bullet or sports ammunition or a sporting weapon, which overcomes the disadvantages of the prior art and in particular the ISPC regulations preferably for a major classification meets while fulfilling safety requirements, for example, according to C. I. P. and / or SAAMI.

This object is achieved by the subject matter of independent claim 1.

Accordingly, a sports floor with a sports cartridge is intended in particular for dynamic IPSC shooting. The sports floor is designed as a preferably encapsulated solid shell projectile especially with lead core and / or copper sheath. The full coat around the preferred lead core serves to improve the environmental compatibility of the sports floor while reducing smoke and pollution. An encapsulated solid shell projectile has a core, for example a lead core, which is completely enveloped by a jacket, for example a copper jacket, which further reduces the smoke and pollutant load and is therefore particularly well suited for use in covered courses. The sports floor according to the invention has a cylindrical guide portion mm holding the sports bullet in a propellant charge case of the sports cartridge and for guiding the sports bullet in a barrel of a sporting weapon. Furthermore, the sports floor on a front portion with tapered end portion. A taper, for example, be at least partially round, in particular ogive-shaped, and / or at least partially conical, in particular frusto-conical. It is clear that the sports floor is a preferably rotationally symmetrical rotation body. The sports floor defines in particular transversely to its longitudinal extent a radial direction. It is clear that a sports cartridge with a sports bullet according to the invention is a preferably rotationally symmetrical body of revolution.

According to the guide section of the sports bullet is offset relative to the front portion in the radial direction to the outside. Preferably, the cylindrical guide portion has a diameter that is constant along the axial direction. The radial offset is provided between the outer diameter of the cylindrical guide portion and the outer diameter, in particular the radially largest outer diameter of the likewise cylindrical front portion of the sports floor. The radial offset is preferably at least 0.01 mm, at least 0.05 mm, at least 0.06 mm, at least 0.075 mm or at least 0.09 mm. The radial offset may be, in particular, not more than 1.00 mm, not more than 0.50 mm, not more than 0.40 mm, not more than 0.30 mm, or not more than 0.20 mm. The radial offset is preferably 0.10 mm ± 0.05 mm, more preferably 0.10 mm ± 0.02 mm, particularly preferably 0.10 mm ± 0.01 mm. It should be understood that the radial offset is preferably defined fully in the radial direction between the outside of the guide portion and the outside of the front portion.

A difference in diameter between the preferably largest outer diameter of the front section, in particular adjacent to the guide section and the preferably constant diameter of the cylindrical guide section corresponds to twice the radial offset. The preferably largest diameter of the front section, in particular adjacent to the guide section, is in particular between 95% and 99%, preferably between 97% and 98% of the preferably largest, in particular constant, diameter of the guide section. The radial offset between the guide portion of the sports floor according to the invention and the front part or front portion of the sports floor according to the invention is preferably selected caliberabhängig that the front portion can remain completely contact-free against the barrel of a sporting weapon when firing the sports projectile by means of the sports weapon. Preferably, the projectile diameter, in particular the guide section diameter, substantially corresponds to the tensile profile diameter of the barrel of the sports weapon. Preferably, the particular largest outer diameter of the front part of the sports floor caliber is dependent smaller than the field profile diameter of the barrel of the sporting weapon. The preferably largest outer diameter of the guide section can be at least as large as the field profile diameter and / or at most as large as the Zugprofil- Diameter of the barrel of the sports weapon with which the sports floor is to fire. In particular, the sports floor according to the invention consists of a guide section and a front section. 9 mm Luger 38 special 40 S & W 44 Rem.

By a sports floor according to the invention is designed such that between the outer diameter of the guide portion and the outer diameter of the front portion of the sports projectile a radial offset is provided, it is achieved that the standing during the firing of the sports projectile with the barrel of the sporting weapon in contact area of the sports floor and the concomitant sliding friction is significantly reduced. In this way, frictional losses can be significantly reduced. By reducing the sliding friction between the sports floor and the barrel, the sports floor according to the invention can achieve significantly higher exit speeds than conventional sports floors. In this way, the power factor score of the sports floor required for the IPSC classification Minor or Major is significantly increased. At the same time, reducing the sliding friction between the sports floor and the barrel means that the propellant expands due to the ignition of the propellant, less resistance is provided by the sports floor than usual, so that the maximum gas pressure occurring at the launch of the sports floor according to the invention can be significantly reduced. By improving the sliding properties of the sports bullet in the barrel, it is surprisingly possible at the same time to achieve a higher ballistic performance and an improved compliance with the C.I.P specifications, in particular with regard to the maximum permissible gas pressure.

Preferably, the sports floor is provided up to a caliber of 20 mm, in particular up to a caliber of 12 mm. Sports cartridges usually consist of a sports floor, a propellant charge, propellant and a primer. The sports floor is the object shot down by the sporting weapon. The weight of a sports bullet may preferably be between 3 g and 20 g, in particular between 5 g and 15 g, particularly preferably between 5.5 g and 9 g. In particular, the sports bullet for the caliber 9 mm Luger, .357 Mag., .40 S & W, .44 Rem. Mag. Or .45 ACP.

According to a preferred embodiment of a sports floor according to the invention, the guide section comprises a step, which extends in particular in the radial direction inwards at the front end of the guide section to the front section. Preferably, the step extends transversely to an axial direction of the sports floor. The stage may include a phase and / or a transition radius. In the axial direction, the step extends in particular over less than 0.5 mm, less than 0.2 mm, less than 0.1 mm or less than 0.05 mm, preferably less than 0.01 mm. In particular, the step extends substantially orthogonal to the axial direction of the sports projectile. The step can form the front end of the guide section. Preferably, the front portion of the sports bullet connects in the axial direction directly to the step of the guide portion.

According to a preferred embodiment of a sports floor according to the invention, which can be combined with the previous, the length of the guide portion or guide length in the axial direction A is less than 50%, in particular less than 40%, preferably less than 30% of the total length of the sports floor. Preferably, the guide length is greater than 5%, preferably greater than 10%, more preferably greater than 20% of the sports floor length. According to a particularly preferred embodiment of a sports projectile according to the invention, the guide length can be between 25% and 30%, in particular between 27% and 29% of the projectile length. The total axial length of the sports floor or sports floor length may be greater than 10 mm and / or less than 20 mm, in particular greater than 12.5 mm and / or smaller than 16 mm, more preferably at least 14 mm and / or at most 15 mm. Particularly preferably, the axial projectile length is between 14.0 mm and 14, 4 mm. Additionally or alternatively, the guide section extends in the axial direction A of the sports floor over a total length or guide length of at least 2 mm and / or at most 6 mm, in particular at least 3 mm and / or at most 5 mm, preferably over at least 3.5 mm and / or at most 4.5 mm, more preferably above about 4 mm. The outer diameter of the guide section is at least in sections, preferably over a large part of the length of the guide section in the axial direction, in particular over the entire length of the guide section Guide section in the axial direction, in particular up to the stage, constant. By making the guide length relatively short in relation to the projectile length, the range of sliding friction between the sports floor and the barrel is minimized. By selecting a minimum guide length ensures that the possibility of a sufficiently deep insertion depth of the sports floor in the cartridge case of the sports cartridge is feasible to keep the solid floor before launching safely in the propellant charge sleeve.

According to a preferred embodiment of a sports projectile according to the invention, which can be combined with the previous one, the front section has a preferably cylindrical central section which extends between the guide section and the front section and preferably has a continuously smaller diameter than the diameter of the guide section. The middle section defines a mid-section length which is at least 20%, in particular at least 25%, preferably at least 30%, of the total length of the sports projectile in the axial direction. In particular, the middle section length may extend from the front end of the guide section in the axial direction over at most 60%, preferably at most 50%, particularly preferably at most 45% of the projectile length in the axial direction A and / or less than 7 mm, in particular less than 6 mm, preferably at most 5, 2 mm. According to a particularly preferred embodiment of a sports projectile according to the invention, the middle section length is between 35% and 45% of the projectile length, in particular between 38% and 40%.

The preferably cylindrical central portion may define an outer diameter that extends constant or at least substantially constant in the axial direction between the guide portion and the forehead portion of the sports floor. The preferably constant and / or largest outer diameter of a particular cylindrical central portion may be caliber-dependent smaller, preferably less than 1 mm smaller, more preferably less than 0.1 mm smaller, designed as the field profile diameter of the barrel of the sporting gun. By a sports floor is equipped with a cylindrical or approximately cylindrical central portion which extends over a portion of the sports floor in the axial direction of the front end of the guide section, the available for the sports floor volume can be optimally utilized with limited expansion in the axial direction, so that a bullet with the highest possible mass can be provided. In this way, the power factor score defined according to the IPSC rules of the sports floor according to the invention can be further increased, in particular to achieve the minimum power factor number threshold for minor classification or the threshold for major classification.

According to a preferred embodiment of a sports projectile according to the invention, the end portion tapers conically and / or arcuately at least in sections, in particular arcuately ogival. In particular, the end section comprises a cone section with an opening angle of less than 60 °, preferably less than 50 ° and / or greater than 30 °. In particular, the opening angle of the cone section can be about 40 °. Preferably, the top of the projectile is rounded. Between the rounded tip and the tapered end portion, a rounded edge having a radius of 5 mm or less, for example, 1 mm, 2 mm or 3 mm, may be conically arranged. The at least partially conically and / or arcuately tapering section, preferably the cone section, preferably extends in the axial direction over a length of less than 10 mm, in particular less than 6 mm, preferably less than 5 mm. The length of the tapering section, in particular of the cone section, is preferably at least 2 mm, in particular at least 3 mm, preferably at least 4 mm. According to a particularly preferred embodiment, the tapering section, in particular the cone section, preferably extends between a particularly rounded tip and a preferably cylindrical central section over a length of 4 mm to 6 mm, in particular 4.5 mm to 5.5 mm, preferably 4 , 7 mm to 4.9 mm. The tapered front section ensures good aerodynamics of the sports floor. Surprisingly, it has been found that even with a deviation from the usually considered as a particularly safe bullet feed necessary Ogivenform good Zuführungs- and flight characteristics can be achieved.

According to a preferred embodiment of a sports floor according to the invention, which can be combined with the previous, the sports floor on the rear side has a particular coaxial and / or concentric recess, such as a dome on. A recess can be designed, for example, conical, in particular conical or frusto-conical. Preferably, the recess is realized as a part spherical dome, wherein the radius of the dome may be greater than half the radius of the guide portion. A calotte radius may preferably be between 2 mm and 4 mm. In particular, a calotte radius may be 3 mm ± 0.15 mm. By a recess is introduced at the foot or tail of the sports floor, in particular a dome, the space available for propellant cavity is increased, which is determined by the sports floor and the propellant charge sleeve in which the basement can sit. By the Providing a larger propellant volume, more propellant can be absorbed, which can be converted into more expansion energy to accelerate the projectile to be fired. In this way, a higher exit speed of the sports floor can be achieved from the sports weapon. With regard to the IPSC classification, it has turned out to be particularly favorable if, in the case of a sports floor, both a cutout is made in the rear and a relatively large, in particular cylindrical, middle section is provided.

The invention also relates to a sports cartridge, in particular for dynamic IPSC sports shooting, having a sports bullet as described above, preferably precisely a sports bullet constructed according to one of the preceding claims, and a propellant charge case having a cavity for receiving propellant and a neck portion in which the guide portion the sports floor is held. In particular, the sports cartridge may include a primer for igniting the propellant. The cavity of the propellant charge sleeve may have a plurality of sections, for example a rearward, preferably frustoconically widening first section and a second, preferably frontal cylindrical sleeve section which forms the neck section. Preferably, the sports cartridge is a pistol cartridge or a revolver cartridge. Of the CIP regulations, the total length of the cartridge is limited caliber depending on a maximum dimension, which is measured from the rear of the propellant charge sleeve to the top of the sports floor. The sports floor is preferably configured in such a way that the total length of the sports floor or sports floor length is caliber-dependent or equal to the permissible cartridge total length according to CIP. 9 mm Luger 38 special 40 S & W 44 Rem.

By taking advantage of the maximum permissible length permitted by C.I.P. Regulations, the maximum possible volume for receiving the mass of the sports bullet, in particular lead core, and the maximum space for receiving propellant can be utilized for the sports cartridge.

Preferably, the sports cartridge is a particular rotationally symmetric body of revolution, which defines an axial direction and a radial direction. Preferably, the propellant charge sleeve is a particular rotationally symmetrical body of revolution, which defines an axial direction and a radial direction. To define the axial direction of the sports cartridge, the sports projectile is preferably inserted coaxially and / or concentrically in the propellant charge sleeve.

According to a preferred embodiment of a sports cartridge according to the invention the sports bullet is inserted so deep in the axial direction in the propellant charge sleeve that the guide portion is disposed at least 50%, in particular at least 75%, preferably at least 90% of the guide section length within the propellant charge sleeve. Particularly preferably, the sports floor is inserted so deep in the axial direction in the propellant charge sleeve that the entire guide length of the guide portion is arranged in the propellant charge sleeve.

Alternatively or additionally, in a preferred embodiment of a sports cartridge according to the invention, the sports bullet is inserted into the propellant charge casing at less than 50% and / or more than 10% of its total projectile length in the axial direction. The total axial length of the sports floor or sports floor length may be greater than 10 mm and / or less than 20 mm, in particular greater than 12.5 mm and / or smaller than 16 mm, more preferably at least 14 mm and / or at most 15 mm. Particularly preferably, the axial projectile length is between 14.0 mm and 14, 4 mm. Preferably, the sports floor is used to 20% to 40% of the projectile length in the axial direction in the propellant charge sleeve, in particular to 30% ± 5%. Alternatively or additionally, in a preferred embodiment of a sports cartridge according to the invention the insertion depth of the sports bullet in the neck portion of the propellant charge sleeve in the axial direction, preferably starting from the end sleeve end, at least 2 mm and / or at most 6 mm, in particular at least 3 mm and / or at most 5 mm , preferably at least 3.5 mm and / or at most 4.5 mm, particularly preferably 4 mm. In this case, the step of the sports bullet may preferably be arranged at the height of the front end of the sleeve. Preferably, the step of the guide section of the sports floor in composite sports cartridge by less than 1 mm, preferably less than 0.25 mm, in particular less than 0.1 mm, offset in the axial direction of the end-side sleeve end. When a sports floor for realizing a sports cartridge as described above is inserted into the cartridge of the sports cartridge, it is ensured that sufficient holding forces are available to hold the sports floor safely in the cartridge, for example, to safely load the magazine of a sports weapon with sports cartridges and / or for safely feeding a sports cartridge from a magazine into a cartridge chamber of a sporting weapon.

According to a preferred embodiment of a sports cartridge according to the invention, which can be combined with the previous one, the sports cartridge comprises a propellant, in particular propellant powder, with progressive and / or offensive combustion behavior. Propellant can be distinguished depending on its burning behavior. A propellant with offensive burning behavior burns quickly with rapid reaching a maximum pressure, so that with offensive burning propellant rapid acceleration of a sports bullet can be achieved. Progressive burning propellant reaches the maximum pressure during firing later, but can deliver greater acceleration energy to a sports floor than a propellant with offensive fuel burning behavior. Progressively burning propellant may be preferred because it generally produces a lower maximum pressure, which facilitates compliance with C.I.P. regulations. Surprisingly, it has been found that, when using a recess at the rear of the sports floor by increasing the available space for propellants, also propellants can be used with offensive burning behavior, the maximum pressure limit according to C. I. P. can be maintained.

The invention also relates to a sports weapon, such as a sports handgun, for example a revolver, a submachine gun and / or a pistol, in particular for dynamic IPSC sport shooting, comprising at least five, preferably six, eight, ten, 15 or 28 sports cartridges, for example as described above, each with a sports floor according to the invention.

According to a preferred development of a sports weapon according to the invention, the barrel of the sports weapon is at least 7.62 cm [3 inches] long and / or at most 12.7 cm [5 inches] long. Preferably, the barrel of a sports weapon according to the invention is at most 85 cm long.

According to a preferred embodiment of a sports gun according to the invention, which is combinable with the previous, the sports gun on a cartridge camp for firing ready storage exactly a sports cartridge, in particular the cartridge chamber has a sleeve neck for axially holding a propellant charge of the sports cartridge and / or in particular the cartridge chamber a preferably has a conically tapered projectile transition, which in particular preferably in the axial direction directly adjacent to the barrel and / or the sleeve neck. In this preferred embodiment of a sports weapon according to the invention one of the at least five sports cartridges is arranged in the chamber, wherein the front portion of the sports projectile arranged in the chamber cartridge sports cartridge, in particular from the sleeve neck and / or through the projectile transition, preferably at least 5 mm, in particular at least mm, in particular between 7.5 mm and 8 mm, extends into the barrel.

According to a preferred embodiment of a sports gun according to the invention, the front portion of the sports floor of the cartridge arranged in the cartridge sports a preferably cylindrical central portion extending between the guide portion and the end portion of the sports projectile, wherein the central portion, in particular from the sleeve neck and / or through the Projectile transition, in particular at least 1 mm, preferably at least 2 mm, more preferably at least 3 mm, extends into the barrel. It is particularly preferred that the central portion does not touch the barrel and / or the bullet transition. Preferably, an annular gap is preferably arranged continuously between the middle section and the barrel or the middle section and the projectile transition in the axial direction. In such a vote of the sports weapon and the sports cartridge with inventive sports projectile can be used a very large volume and thus heavy as bullet, which nevertheless generates only a slight sliding friction at launch, so that a particularly high IPSC power factor can be achieved. Without the gap between the projectile and the barrel or the projectile transition, a comparably heavy projectile without a radial offset according to the invention would have to be inserted significantly deeper into the propellant charge sleeve, which would greatly reduce the available space for the propellant charge.

Further characteristics, advantages and features of the invention are explained by the following description of preferred embodiments with reference to the accompanying drawings, in which:

The sports floor according to the invention shown in the figures or the sports cartridge according to the invention shown in the figures corresponds to the caliber 9 mm Luger. All of the dimensional information related to the preferred embodiment according to the figures can be understood insofar as caliber-dependent dimensions with respect to the caliber 9 mm Luger.

It is clear that a sports floor according to the invention or a sports cartridge according to the invention can also be realized for other calibers (not shown), for example for .357 Mag., .40 S & W, .44 Rem. Mag. Or .45 ACP. Other calibers of possible sports bullets or sports cartridges according to the invention can be .38 Super Auto, .45 Auto 91 IMI, .38 Super Comp, .83 Super Rimeless or 923 Winchester.

This in 1 to 3 illustrated sports floor 3 is an encapsulated solid jacketed bullet with lead core 11 and complete copper cladding 12 , The copper coat 12 closes or encapsulates the lead core 11 to the whole.

The sports floor 3 is composed of a guide section 13 and a front section 15 , In the direction of flight of the sports floor is the front section 15 in front of the guide section 13 , The front section defines the top or front side of the sports floor 3 , The in flight direction of the sports floor 3 rear guide section 13 is ideally cylindrical on the outside and forms the foot or the rear 14 of the sports floor.

In the axial direction A of the sports floor 3 is the front section 15 in front of the guide section 13 of the sports floor 3 arranged. Opposite the front section 15 is the lead section 13 in the radial direction R completely offset by a radial offset X to the outside. The radial offset X can in 1 only to be guessed and is in the 1a and 2 better visible. The width of the radial shoulder X is 0.1 mm. The diameter D _{13 of} the guide section 13 is therefore 0.2 mm wider than the widest diameter of the front section 15 , For sports cartridges 1 or sports floors 3 the caliber 9 mm Luger is the barrel 103 the sports weapon 101 ( 3 ) preferably with a tensile profile diameter of 9.02 mm and a field profile diameter of 8.82 mm. In the invention 1 sports cartridge or the sports floor according to the invention 3 should only the guide section 13 at the launch of the sports floor 13 with the barrel 103 get in touch. The widest diameter of the front section 15 is therefore smaller than the field profile diameter and may preferably be 8.81 mm with a tolerance field plus 0 mm minus 0.03 mm. The guide section diameter D13 preferably corresponds to the tension profile diameter. For the caliber 9 mm Luger, the guide section diameter is therefore 9.02 mm, in particular a tolerance field plus 0 mm minus 0.03 mm. It is clear that a sports floor according to the invention of another caliber can be realized correspondingly according to the caliber-specific dimensions for tensile profile diameter and field profile diameter (see Table 3).

In the in the 1 to 3 illustrated preferred embodiment of a sports projectile 3 The front section is subdivided 15 in several areas. Front side has the sports floor 3 a flat, rounded tip 16 , The rounded tip 16 can have an edge diameter of about 3 mm. The rounded tip may have a radius of curvature between 5mm and 10mm, preferably a radius of curvature of about 7mm. At the edge of the ring 22 , which may preferably have a radius of curvature of about 1 mm, goes the rounded tip 16 over a tapered section. In the execution according to 1 to 3 is this tapered section as a cone section 18 realized.

The cone section 18 has a cone opening angle of about 40 °. Starting from the top 16 of the sports floor 3 extends the frontally tapered or rearward widening section 17 here in sections as a cone section 18 is realized, up to its maximum diameter at a profile transition 24 less than 6 mm, for example 4.8 mm, in the axial direction A. At the second ring edge or transition 24 For example, a radius of curvature of, for example, 2 mm may be provided. In front of the ring crossing 24 extends the full tapered forehead section 17 of the sports floor 3 , Heckwarts of the ring transition 24 extends to the guide section 13 a middle section 19 which has a cylindrical outer contour in the preferred embodiment shown here. The middle section 19 may also be referred to as a cylindrical section, since it is between the guide section 13 and the tapered forehead section 17 has over its entire extent in the axial direction A substantially a constant diameter D ₁₉ . The middle section diameter D ₁₉ thus corresponds to the largest diameter of the front section 15 of the sports floor 3 , The cylindrical middle section 19 extends over more than a third of the total length L _{G of} the sports floor 3 , The mid-section length L _M between the step 21 and the profile transition 24 is less than 5.2 mm. From the stern 14 is the profile transition 24 less than about 9.6 mm away. In a 9 mm Luger sports floor 3 the projectile length L _{G can be} about 14.4 mm. The length L _{M of} the middle section 19 can at the 9 mm Luger sports floor 3 at least 3 mm, preferably at least 4.5 mm, in particular at least 5 mm in size.

The transition between the middle section 19 of the front section 15 of the sports floor 3 and the guide section 13 is by a radial offset X in the form of a step 21 formed according to the preferred embodiment shown here extends perpendicular to the axial direction A in the radial direction R. It is clear that instead of an extension perpendicular to the axial direction A, a step 21 can also be realized in the form of a phase or a rounded transition. It is important that the front section 15 has an outer diameter, which is preferably constant, in particular completely smaller than the outer diameter D _{13 of} the guide portion 13 and in particular smaller than the caliber-dependent field profile diameter.

At the stern 14 , which may be substantially flat, is a recess in the form of a part-spherical dome 23 in the sports floor 3 brought in. Compared to a hypothetical cartridge with a flat-bottomed bullet, the calotte provides 23 in the propellant charge case 5 used, an additional space for receiving propellant 8th ready. In this way, the amount of blowing agent 8th in a sports cartridge 1 be increased, in particular by 5%, preferably by 10%, particularly preferably by 14% or more. The starting from the guide section 13 in the axial direction A pulled forward cylindrical central portion 19 it allows that through the calotte 23 Dropped volume or the fallen mass of the sports floor 3 compensate. By the combination of dome 23 and cylindrical center section 19 can at a given sports cartridges total length or sports cartridge length L _P at the same sport floor mass of the available cavity 51 for picking up propellant 8th be increased.

The sports floor 3 is starting from the front end 55 the propellant charge case 5 inserted in the axial direction A by an insertion depth L _E. Along the insertion depth L _E holding forces of the propellant charge sleeve 5 on the sports floor 3 be exercised to the sports floor 3 safely in the propellant charge case 5 to keep. The front area of the propellant charge case 5 in which the sports floor 3 can, as a neck section 53 be designated. The insertion depth L _E preferably corresponds approximately to the entire axial length L _{F of} the guide section 13 of the sports floor 3 ,

The length of the sleeve L _H between the front end 55 and the stern 57 the sleeve 5 preferably corresponds to the caliber-dependent regulatory requirements and can in the illustrated caliber 9 mm Luger sports cartridge 1 be about 19.15 mm. The outer diameter of the illustrated sports cartridge 1 has in the area of the neck section 53 a maximum width of 9.65 mm and in the area of the sleeve tail 57 a maximum width of 9.96 mm.

The cartridge length L _{P of} a sports cartridge 1 The 9 mm Luger caliber is approximately 29.69 mm with a tolerance range of preferably plus 0 mm minus 0.6 mm. The cartridge length L _P is measured between the top 16 of the sports floor 3 and the sleeve tail 57 , The one for the sports floor 3 and the propellant 8th available space is therefore limited to specific caliber. By choosing the smallest possible insertion depth L _{E of} the sports floor 3 in the propellant charge case 5 gets as much cavity as possible 51 in the drift landing pod 5 for absorbing propellant 8th leave. That at the rear end of the tail 57 the propellant charge case 5 used primer cap 7 serves to propellant 8th to fire the sports cartridge 1 to ignite.

As in the detailed representation according to 1a can recognize the vertical step 21 of the sports floor 3 preferably flush with the front end of the sleeve 55 the propellant charge case 5 to lock. The front section 15 is then completely outside the propellant charge sleeve 5 and comes at the firing of the sports floor 3 not in contact with the barrel. As in 1a can be clearly seen, the radial offset X between the guide section 13 and the front section 15 preferably smaller than the coat formed in particular of copper 12 the sports floor, for example, less than half as large, preferably less than a quarter of the thickness of the shell 12 , Also good to see in 1a is that the radial offset X between the front section 15 and the guide section 13 smaller than the wall thickness, preferably half the wall thickness of the neck portion 53 ,

In 2 is the sports floor according to the invention 3 without the remaining sports cartridge components shown. The length L _{F of} the guide section 13 extends from the stern 14 of the sports floor 3 right up to the stage 21 passing the transition between leadership section 13 and the front section 15 , or the middle section 19 , forms. The maximum outer diameter D _{13 of} the guide section 13 Expands in the axial direction A over more than half of the guide length L _F , preferably over more than 75% of the axial guide length L _F , preferably almost completely over the entire guide length L _F. At the stern 14 of the sports floor 3 a transition radius may be formed, which, for example, due to manufacturing due to the jacket 12 may be necessary, wherein the transition radius between the cylindrical outer contour of the guide portion 13 and the stern 14 between 0.5 mm and 5 mm, preferably between 1 mm and 2 mm, can be large. Instead of the part-spherical calotte 23 that is coaxial and concentric at the stern 14 of the sports floor 13 is formed, a differently shaped recess, for example a conical or frusto-conical recess can be realized. The recess is in particular between 1 mm and 7 mm, preferably between 2 mm and 5 mm, particularly preferably about 3 mm deep.

3 shows the sports cartridge according to the invention 1 with projectile according to the invention 3 in the run 103 and cartridge storage 105 a sports weapon 101 , The cartridge chamber 105 is caliber dependent according to the sports cartridge 1 realized. The cartridge chamber 105 has a sleeve intake 106 with a diameter for holding the propellant charge sleeve 5 the sports patrone 1 is measured.

The front end of the recording room 106 gets through a sleeve neck 109 the sports weapon 101 formed, which forms a radially, transversely to the axial direction A, in particular perpendicular to the axial direction A, inwardly projecting shoulder. The front sleeve end 55 pushes in the axial direction A against the sleeve neck 109 the sports weapon 101 , The inner diameter of the sleeve neck 109 the sports weapon 101 is larger than the inside diameter of the barrel 103 , Between the run 103 and the sleeve-receiving space 106 is a so-called projectile transition 107 formed having a tapered in the axial direction A forward (in the weft direction) truncated cone shape. The floor transition 107 is part of the cartridge warehouse 105 , The cartridge chamber length L _L extends in the axial direction A via the receiving space 106 and the floor transition 107 , To the chamber 105 closes in the axial direction A preferably immediately the run 103 on, which has a caliber-dependent Zugprofil diameter and a caliber-dependent field profile diameter.

The area around the floor transition 107 is shown in detail in the view III, which in 3a is playing. In 3a can be the ratio of running field profile, running train profile, guide section 13 and front section 15 detect. The front section 15 of the sports floor 3 is opposite the inner contour of the barrel 103 without contact. Between the front section 15 and the inside diameter of the barrel as well as the inside diameter of the bullet transition 107 is an annular gap 111 educated.

In 3a a dash-dot-dot contour line k is shown, which is an extension of the outer contour of the guide section 13 symbolized in the axial direction A. The imaginary guide section contour line k initially runs in the entrance area of the storey transition 107 through the annular gap 111 , but then penetrates later in the floor transition 107 in the material area of the barrel 103 one. The guide section 13 of the sports floor 3 should by the field profile of the barrel 103 be guided and put into spin.

4 and 5 are diagrams which, depending on the nature of the propellant, schematically represent the pressure development p and the velocity evolution v of the sports bullet depending on the bullet position in the course. In 4 and 5 the abscissa axis represents the position of the projectile in the course 4 The ordinate axis schematically represents the gas pressure during the firing of the projectile and at 5 the bullet speed.

The solid line refers to the pressure development p _O or the velocity development v _O when firing a sports projectile with an offensive propellant. The dashed or dotted line symbolizes the pressure development p _P or the velocity development v _P in a sports projectile which is fired with a propellant with progressive fire behavior. A propellant with offensive fire behavior burns down quickly, so that the sports floor is accelerated quickly. However, in the pressure development p _{o of} an offensive blowing agent, a high maximum gas pressure occurs, especially in comparison to the use of a progressive blowing agent. Since the energy released by the slower fire at progressive pressure development p _{P is} greater than the energy emitted at offensive p _O , a sports floor can be accelerated to a higher speed using propellants with progressive fire behavior.

The features disclosed in the foregoing description, the figures and claims may be of importance both individually and in any combination for the realization of the invention in the various embodiments.
