摘要： The present invention provides a high-precision spherical single-headed bullet, including a spherical warhead, a circular cylindrical bullet support and a cardboard bullet support which are arranged in a smoothbore tube; an inner cavity of the smoothbore tube is filled with a propellant; the cardboard bullet support is arranged above the propellant at the rear end of the smoothbore tube in a closed manner; one end of the cardboard bullet support away from the propellant is provided with the circular cylindrical bullet support; an inner cavity of the circular cylindrical bullet support is provided with a firing hole; and the spherical warhead is arranged at the upper end of the firing hole of the circular cylindrical bullet support. According to the present invention, the spherical warhead has natural relative stability in flight, higher shooting accuracy and strong penetrating power, and is low in price and easy to process.

摘要： Systems, methods and apparatus are provided through which in some implementations an ammunition cartridge includes a cartridge casing having a longitudinal center axis, a powder pocket positioned adjacent to the cartridge casing, a piston bore positioned adjacent to the powder pocket, a piston in the piston bore, and a payload bay positioned adjacent to the payload bay, wherein the piston is not coupled to the cartridge, wherein the piston is in contact with the payload bay wherein a diameter of the powder pocket is less than an inside diameter of the cartridge casing to provide a reduced velocity to the payload.

摘要： Devices and methods for shotshell cartridges, particularly shotshell cartridges with biodegradable components. One or more of the casing, shot wad, spacer, and powder wad may be formed of biodegradable materials. A biodegradable shot wad is manufactured of cellulosic fibers and wax to provide obturation and gas seal properties at high pressures with high reliability.

摘要： Disclosed is an intermediate part forming a wadding cup to be placed in the case of a cartridge for separating the explosive charge and the shot. It includes a cylindrical sleeve of outer diameter suitable for being inserted slidingly into the case, the sleeve having a front portion the end of which is open, suitable for containing the shot, and a rear portion including a cylindrical wad flush with the end of the rear portion, the intermediate part being formed of at least 95% by weight of biodegradable or decomposable materials, such as cardboard and cork. Also disclosed is a biodegradable cartridge with cup and wadding, complying with environmental rules.

摘要： Herein we describe cartridges, including for shotgun shells, utilizing a particulate obturating medium to provide a gas seal. The obturating medium comprises particles having an average particle size greater than 212 microns, and an average specific gravity greater than 1.1. Such cartridges are particularly useful as shotshell cartridges used as blanks, less lethal loads, hunting loads, target loads, and barrel-cleaning loads. Methods for loading and use are described, as well as different particulate obturating media.

摘要： This invention relates to less-lethal munitions. More particularly, the invention relates to a wad and a less-lethal round of ammunition adapted for use with a conventional firearm, which less-lethal shell enables the firearm to propel less-lethal projectiles therefrom. According to a first aspect of the invention there is provided a wad operatively received within an ammunition casing, the wad comprising a substantially disc-shaped base; and a plurality of tabs extending from the base defining a receiving zone therebetween, with at least some of the tabs provided with an inwardly projecting formation for urging against a projectile operatively received within the receiving zone.

摘要： The present invention is directed to a projectile configured to provide a submunition payload across a wide impact pattern, similar to that of a shotgun, at a range typically beyond the capability of standard shotgun rounds. The additional range is provided in some embodiments of the invention by allowing the tailoring deployment range of the submunition payload based upon a given threat.
