Abstract

Claims (28)

1. A high strength polymer-based cartridge for subsonic ammunition comprising:

a first end having a mouth;

a projectile disposed in the mouth;

a shoulder, disposed below the mouth, forming a bottleneck cartridge;

a wall, molded from a polymer, between the first end and a second end opposite the first end;

an insert joined to the second end, comprising:

an extraction rim and a groove both disposed at one end of the insert; and

a primer pocket in fluid communication with a flash hole, the flash hole in fluid communication with a propellant chamber; and

a sleeve section;

wherein the sleeve section and the wall form the propellant chamber;

wherein the sleeve section and the wall comprise a thickness at least 1.25 times greater than a standard thickness of a wall of a standard cartridge,

wherein the propellant chamber between the mouth and the insert is unobstructed, and

wherein the propellant chamber comprises a powder load having a load density greater than 40%.

2. The high strength polymer-based cartridge of claim 1 , wherein the sleeve section further comprises:

a first inner wall comprising a first diameter; and

a second inner wall comprising a second diameter;

wherein the first inner wall extends from the shoulder to the second inner wall;

wherein the second inner wall extends from the upper inner wall to the insert; and

wherein the first diameter does not equal the second diameter.

3. The high strength polymer-based cartridge of claim 1 , wherein the sleeve section further comprises:

a first inner wall having a first slope;

a second inner wall having a second slope; and

wherein the first slope extends between the shoulder and the second inner wall;

wherein the second slope extends between the first inner wall and the insert; and

wherein the first slope does not equal the second slope.

4. The high strength polymer-based cartridge of claim 1 , wherein the propellant chamber permits only enough propellant to propel the projectile engaged in the cartridge casing at subsonic speeds.

5. The high strength polymer-based cartridge of claim 1 , wherein the insert is made from a metal, an alloy of metals, or an alloy of a metal and a non-metal.

6. The high strength polymer-based cartridge of claim 1 , wherein the projectile has a conventional weight for a caliber of the projectile.
