Abstract
A high strength polymer-based cartridge casing includes an upper component of polymer, a bullet of a standard weight, a lower component of polymer, and an insert. The upper component has a shoulder portion and an upper component inner wall has a first slope extending from the shoulder. The lower component has a lower component inner wall having a second slope. The upper and lower component inner walls form a propellant chamber; and the first and second slopes reduce a volume of the propellant chamber. The reduced volume of the propellant chamber permits only enough propellant to propel a bullet engaged in the cartridge casing at subsonic speeds.
Claims6
A high strength polymer-based subsonic ammunition comprising:
- an upper component, molded from a polymer, comprising:
- a first end having a mouth and a neck;
- and
- at least an upper inner wall between the first end and a second end of the upper component opposite the first end, and having a first slope;
- a projectile having a standard weight removably engaged with the mouth;
- a lower component, molded from a polymer, joined to the upper component, comprising at least a lower inner wall between the upper component and a flash hole and having a second slope;
- and
- a propellant chamber formed by the upper and lower inner walls, the first slope does not equal the second slope, and the first and second slopes are configured to reduce a volume of the propellant chamber to permit only enough propellant to propel the projectile at subsonic speeds.
A high strength polymer-based subsonic ammunition comprising:
- an upper component, molded from a polymer;
- a bullet, having a standard weight, removably engaged with the upper component;
- a lower component, molded from a polymer, and engaged the upper component;
- an insert engaged to the lower component;
- a shoulder portion of the upper component;
- an upper component inner wall having a first slope extending from the shoulder and directed toward the lower component;
- a lower component inner wall having a second slope extending from the upper component toward the insert;
- a propellant chamber formed from the upper and lower component inner walls, the first and second slopes reduce a volume of the propellant chamber and the first and second slopes do not equal each other,
- wherein the reduced volume of the propellant chamber is configured to permit only enough propellant to propel the bullet at subsonic speeds.
