Abstract
A cartridge casing comprises a casing tube having a first end and a head cap. The first end of the casing tube abuts and is joined with the head cap such that an orifice in the first end of the casing tube is aligned with a passage in the head cap to define a flash passage. The head cap and casing tube are held together by a deformable member.

A cartridge casing comprising:
- a casing tube having a first end provided with a corner edge;
- and
- a head cap provided with a shoulder edge;
- wherein the first end of the casing tube abuts and is joined with the head cap such that the corner edge of the casing tube sits within the shoulder edge of the head cap;
- wherein an orifice in the first end of the casing tube is aligned with a passage in the head cap to define a flash passage;
- and
- wherein the head cap and casing tube are held together by a deformable member which provides a mechanical joint between the head cap and casing tube.

A method of manufacturing a cartridge casing, the method comprising:
- forming a casing tube by a first process, the casing tube having a first end provided with a corner edge;
- forming a head cap by a second process, the head cap provided with a shoulder edge;
- and
- joining the casing tube and head cap by third process, such that the first end of the casing tube abuts and is joined with the head cap such that the corner edge of the casing tube sits within the shoulder edge of the head cap, wherein an orifice in the first end of the casing tube is aligned with a passage in the head cap to define a flash passage, and wherein the head cap and casing tube are held together by a deformable member which provides a mechanical joint between the head cap and casing tube.

A cartridge casing comprising:
- a casing tube comprising a single wall, said case tubing having a first end provided with a corner edge;
- and
- a head cap provided with a shoulder edge, wherein the first end of the casing tube abuts and is joined with the head cap such that the corner edge of the casing tube sits within the shoulder edge of the head cap, and such that an orifice in the first end of the casing tube is aligned with a passage in the head cap to define a flash passage;
- and
- wherein the head cap and casing tube are held together by a deformable member;
- and
- wherein the deformable member extends through the passage in the head cap and through the first end orifice to thereby define the flash passage, which provides a mechanical joint between the head cap and casing tube.
