Abstract
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.
Claims19
A multiplex cartridge comprising:
- a) a cartridge case having a fore end and an aft end, the cartridge case comprising a primer situated at the aft end;
- b) a propellant adjacent the primer;
- c) an obturating component adjacent the propellant and a first payload adjacent the obturating component, wherein the obturating component comprises a pre-formed gas seal having a deformable skirt and a non-deformable body;
- and
- d) a separating component adjacent the first payload and a second payload adjacent the separating component;
- wherein the first payload and the second payload comprise projectiles of different sizes.
A method of loading a multiplex cartridge comprising:
- a) providing a cartridge case having a fore end and an aft end, the cartridge case comprising a primer situated at the aft end;
- b) loading a propellant adjacent the primer;
- c) loading an obturating component adjacent the propellant and a first payload adjacent the obturating component, wherein the obturating component comprises a pre-formed gas seal having a deformable skirt and a non-deformable body;
- and
- d) loading a separating component adjacent the first payload and a second payload adjacent the separating component;
- wherein the first payload and the second payload comprise projectiles of different sizes.
A multiplex cartridge comprising:
- a) a cartridge case having a fore end and an aft end, the cartridge case comprising a primer situated at the aft end;
- b) a propellant adjacent the primer;
- c) an obturating component adjacent the propellant and a first payload adjacent the obturating component;
- d) a first separating component adjacent the first payload and a second payload adjacent the first separating component;
- and
- e) optionally, a second separating component adjacent the second payload and a third payload adjacent the second separating component;
- wherein the obturating component comprises a pre-formed gas seal having a deformable skirt and a non-deformable body and a length-to-width ratio of from about 1 to about 1.4.
