摘要： A duplex projectile cartridge system (e.g., 400) for use in a standard rifle (e.g., 10) has a front bullet (e.g., 320) and a substantially cylindrical back bullet (e.g., 440) coaxially aligned with one another. The front bullet's base is held in the cartridge case neck far enough to engage the back bullet's front surface so that the case neck simultaneously bears upon the front bullet and the back bullet. Optionally, the cartridge configuration orients the back bullet and defines one or more gas bypass lumens to allow expanding gas to initially bypass the back bullet and drive the front bullet distally to force an inter-bullet gap (e.g., “IBG” 480) upon firing.

摘要： Shotshell type ammunition includes a hull, a wad member disposed within the hull, and at least one projectile disposed within at least partially the hull. The hull has a rimless proximal end that includes a primer for firing the ammunition. The hull also has a seat surface for seating the hull against a complementary seat surface in a firing chamber of a firearm. The seat surface is located a distance from an outer end surface of the hull at the rimless proximal end. The hull further includes an outer side surface extending from the rimless proximal end of the hull to the seat surface of the hull. Methods of fabricating such ammunition include forming such a hull, and providing a wad member and one or more projectiles at least partially within the hull.

摘要： This disclosure relates to cartridges, including shotshell cartridges, for launching multiplex projectile loads that contain different sizes or types of projectiles, and methods of loading the cartridges. In one aspect, for example, the present cartridges can contain an obturating component adjacent the cartridge propellant, a first payload adjacent the obturating component, a separating component adjacent the first payload, and a second payload adjacent the separating component. Shotshells of this configuration in which the first (aft) payload comprises birdshot and the second (forward) payload comprises buckshot are particularly useful.

摘要： A weapon for accurately launching a projectile of a firearm toward a target and no other point of strike, comprising an electrically-actuated firearm with axially-stacked ammunition loads, a target sensor unit which generates a target sensor signal at such times as the projected bullet's point of strike and the projected target position coincide; a fire controller which generates a firing signal when both a trigger signal and a target sensor signal are present; and a sequence controller actuated by the firing signal to ignite one or more of the axially stacked ammunition loads to cause the projectile to strike the projected location of a target.
