Abstract

An example of a high strength polymer-based linked cartridge can have a casing inclosing a volume with a mouth and a neck extending away from the mouth. Next, there is a shoulder extending below the neck and a body extending below the shoulder. The body has a finger disposed on a first side of the body, the finger having a length and at least two fingers disposed on a second side of the body. The body also has a pawl catch disposed on a third side of the body. The at least two fingers can be spaced from each other a distance approximately equal to the length, and they can be configured to engage a finger disposed on a second cartridge.

Claims

1. A high strength polymer-based linked cartridge casing inclosing a volume, comprising:

a first end having a mouth;

a neck extending away from the mouth;

a shoulder extending below the neck and away from the first end;

a primer pocket disposed at a second end opposite the first end;

a body extending below the shoulder, comprising;

a finger integrally disposed on a first side of the body having a length;

at least two fingers integrally disposed on a second side of the body; and

a pawl catch integrally disposed on a third side of the body,

wherein the at least two fingers are spaced from each other a distance approximately equal to the length, and

wherein the at least two fingers are configured to engage a finger disposed on a second cartridge, and

a flash hole disposed between the first and second end.

2. The high strength polymer-based linked cartridge casing of claim 1, wherein the least two fingers rotatingly engage the finger of the second cartridge.

3. The high strength polymer-based linked cartridge casing of claim 1, wherein at least one of the finger and the at least two fingers are shearable from the body.
