Abstract
The present invention provides a subsonic ammunition including a polymeric casing body; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber; a propellant disposed and confined within the propellant chamber; a primer insert positioned at the body base and in communication with the propellant chamber; a primer and diffuser disposed in the primer insert in combustible communication with the propellant; and a projectile frictionally fitted in the mouth in combustible communication with the propellant.
Claims17
A subsonic ammunition comprising:
- a primer insert comprises a top surface opposite a bottom surface, a substantially cylindrical coupling element extending away from the bottom surface forming, a primer recess in the top surface that extends toward the bottom surface, a primer flash aperture positioned in the primer recess to extend through the bottom surface, a flash aperture groove in the primer recess that extends circumferentially about the primer flash aperture, and a flange that extends circumferentially about an outer edge of the top surface;
- a polymeric casing body comprising a generally cylindrical hollow polymer body molded over the substantially cylindrical coupling element, into the primer flash aperture and into the flash aperture groove and extending toward a mid-body coupling joint;
- a nose comprising a projectile aperture that extends to a neck connected to a shoulder that transitions from the projectile aperture to a nose coupler, wherein the nose coupler is connected to the mid-body coupling joint;
- a propellant chamber formed between the projectile aperture and the primer flash aperture;
- a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber by at least 10%;
- a propellant disposed in the propellant chamber;
- a diffuser ring having a diffuser aperture positioned in the primer recess aligned with the primer flash aperture;
- a primer disposed in the primer recess in contact with the diffuser ring in combustible communication with the propellant;
- and
- a projectile frictionally fitted in the projectile aperture in combustible communication with the propellant.
