摘要： The invention relates to a shotgun cartridge case and to a shotgun cartridge made therefrom. The case is made in one piece from injection-moulded plastic material and has a cylindrical wall and a base portion with a central opening for a primer. A set of peripherally situated heels (18) is attained by means of grooves extending from the end plane of the base portion, preferably a pair of concentric circular grooves (13, 14) and radial grooves (15) connecting the circular grooves, which grooves have a substantial extension in the axial direction of the case, preferably at least about 2/3 of the minimum axial material thickness of the base portion. These heels absorb the powder charge gas pressure and execute a translatory displacement in the axial direction of the case without the primer hole being deformed, whereby leakage of powder charge gases through the primer hole and displacement of the primer itself are avoided. In one embodiment, the primer opening is enlarged at its region connecting to the powder charge chamber and forms a cavity for receiving an adhesive means in the form of a collar adhered to the primer, thereby providing further insurance against displacement of the primer due to the powder charge gases.
摘要翻译：本发明涉及一种霰弹枪盒壳体和由其制成的霰弹枪筒。该壳体由注射成型的塑料材料制成一体，并且具有圆柱形壁和具有用于底漆的中心开口的基部。通过从基部的端面延伸的槽，优选地一对同心的圆形槽（13,14）和连接圆形槽的径向槽（15）来实现一组周边定位的高跟（18），这些槽在壳体的轴向上具有显着的延伸，优选地是基部的最小轴向材料厚度的至少约2/3。这些高跟鞋吸收粉末充气气体压力，并且在壳体的轴向方向上执行平移位移，而底漆孔不变形，从而避免了粉末装料气体通过底漆孔的泄漏和底漆本身的位移泄漏。在一个实施例中，底漆开口在其连接到粉末充电室的区域处扩大，并形成用于接收粘附到底漆上的衣领形式的粘合剂装置的空腔，由此提供进一步的保险以防止底漆的位移粉末充电气体。

摘要： Firearm projectiles with turbulence-inducing surfaces, firearm cartridges including the same, and associated methods. A firearm projectile comprises a projectile body and a turbulence-inducing surface at least substantially enclosing the projectile body. The firearm projectile is at least substantially spherical. The turbulence-inducing surface is configured to induce a drag crisis in a drag coefficient of the firearm projectile when the firearm projectile travels through air with a Reynolds number that is less than 300,000.

摘要： An ammunition cartridge (50) includes: a basewad (52) disposed within a tube (51) proximate the aft end (56) of the tube (51); a projectile wad (92) disposed within the tube (51) proximate a fore end (59) of the tube (51); a propellant charge (96) disposed within a chamber (94) formed between the projectile wad (92) and the basewad (52); and a projectile (100) disposed within the tube (51) between a forward facing surface (101) of the projectile wad (92) and the fore end (59) of the tube (51). The aft end of the projectile wad (92) has a powder cup skirt (77) formed thereon, and a chamfer (81) is formed around an outer perimeter of a lip (57) of the powder cup skirt (77). The chamfer (81) allows the powder cup skirt (77) to be slidably received within a skirt (80) of the basewad (52) to form the chamber (94). The chamfer (81) provides a clearance at the powder cup skirt lip (57), which helps to insure undisturbed entry into the mouth of the basewad skirt (80).

摘要： A shotgun shell magazine to be received within a mil-spec magazine of an M16/AR-15 mil-spec firearm is disclosed. The magazine has an open top end defining a cavity configured to receive one or more shotgun shells. The magazine body includes a feed lip which partially occludes the open top end and a rim edge including a vertical edge strip which defines a gap in communication with the cavity. A follower having a ramped upper surface resides within the cavity. The follower is biased to direct the shotgun shells toward the open top end until the primer end of a top most shotgun shell engages the feed lip. The top most shotgun shell is angled with respect to the open top end and at least a portion of the closed end of the top most shotgun shell lies above a plane created by the open top end.

摘要： A non-discarding sabot projectile consists of a projectile core; a lower core casing for insertion into a bore of a muzzleloader firearm; and an upper core cap fastly engaged with the lower core casing. Such an engagement between the upper core cap and the lower core casing defines a jacket so that, upon assembly of the lower core casing and upper core cap, the projectile core is encapsulated within the jacket.

摘要： There is provided a lead-free projectile (10), such as a bullet or a ballistic shot, formed by liquid phase sintering or liquid phase bonding of a first particulate (12) having a density greater than lead, a second, ductile, particulate (14) having a melting temperature in excess of 400 DEG C and a binder (16) having a fluidity temperature that is less than the melting temperature of the second particulate (14). Unlike solid phase sintering that tends to produce articles having a porosity of about 20 %, by volume, liquid phase sintering and liquid phase bonding achieve close to 0 % porosity. Reducing the porosity level decreases the amount of high density, first particulate (12), required to achieve a density close to that of lead. One suitable composition for the projectile is ferrotungsten-iron-zinc.
摘要翻译：提供了一种无铅射弹（10），例如子弹或弹道射击，其通过液相烧结或液相粘结形成，该第一颗粒（12）的密度大于铅，第二，延性，颗粒（14），和具有小于第二颗粒（14）的熔融温度的流动性温度的粘合剂（16）。与容易产生孔隙率为约20％（体积）的制品的固相烧结不同，液相烧结和液相粘合实现接近0％的孔隙率。降低孔隙度降低了达到密度接近于铅的密度所需的高密度第一颗粒（12）的量。射弹的一种合适的组合物是铁 - 铁 - 锌 - 锌。

摘要： An apparatus including a ballistic barrel cleaning cartridge is provided. The apparatus includes a casing including a casing recess. The casing recess is closed at a first end of the casing. The apparatus further includes a propellant disposed within the casing recess and an abrasive-binding agent composite slug constructed with an abrasive agent and a polymerized binding agent. The abrasive-binding agent composite slug is disposed within the casing recess at a second end of the casing. Expansion of the propellant is operable to expel the abrasive-binding agent composite slug from the casing recess and propel the abrasive-binding agent composite slug down a bore of a firearm.

摘要： Herein we describe embodiments of shotgun shells, methods for loading such shotgun shells, and methods for using them. In some embodiments, the shotgun shells utilize a multi-component wad system with a biodegradable powder wad that stays intact through the firing process, and a separate and chemically distinct biodegradable shot wad that breaks apart within one meter after being shot out of the barrel of a shotgun. A clean release of the shot can be obtained, providing both high performance and biodegradability. The biodegradable shot wad can be a biodegradable polyester.

摘要： A firearm cartridge with a specially-configured token disc added to its base. The token includes an outer section and a central strike plate. The strike plate includes a strike ball at its center. The presence of the token increases the effective length of the cartridge and thereby prevents the closure of the bolt of a conventional firearm. As a result, the inventive cartridge cannot be fired in a conventional firearm.
