Abstract
A wad for ammunition cartridges, including shotshell cartridges, includes a wad body having a series of separable fingers. A shot confinement tube is located within the wad body, surrounded by the separable fingers. The confinement tube extends longitudinally along the wad body and defines a recess in which an ammunition payload is received and is contained upon firing of the ammunition cartridge and as the wad is separated from the ammunition payload.
Claims11
A unitary wad for ammunition for containing and stabilizing an ammunition payload upon firing, comprising:
- a wad body having a base, a confinement feature extending forwardly and having a substantially solid side wall defining a recess for containing the ammunition payload therein, and a series of separable fingers arranged about the confinement feature;
- said base, confinement feature and series of separable fingers of the wad body being integrally formed;
- wherein after firing, said ammunition payload is contained within said confinement feature as a substantially conglomerated mass for an extended period of confinement as the separable fingers of said unitary wad open about said confinement feature and encounter aerodynamic drag so as to cause the unitary wad to separate from the ammunition payload.
A wad for ammunition, comprising:
- a wad body including a base, a confinement tube having a wall defining a recess for containing an ammunition payload therein, and an upper body portion substantially surrounding and separated from the wall of the confinement tube and having a series of separable fingers formed thereabout;
- wherein the base, confinement tube and upper body portion of the wad body define a substantially unitary wad structure;
- and
- wherein as the wad body is moved forwardly upon firing, the separable fingers open and encounter aerodynamic drag to cause the confinement tube of the wad body to separate from the ammunition payload with the confinement tube containing the ammunition payload for an extended period of confinement during such separation until the containment tube of the wad body has been separated from the ammunition payload.
