Abstract

The present disclosure relates to a construction method for improved tracer ammunition production. There is provided a method of forming a component for a round, said method comprising the step of causing said component to be drawn through at least one floating die.

First claim

The invention claimed is:

1. A tracer projectile comprising:
an inner core; and
an elongate outer sheath, the elongate outer sheath encapsulating the inner core and extending rearwardly of the inner core to provide a cavity for receiving at least one consolidated energetic material, wherein the elongate outer sheath has a maximum wall thickness variation of 0.03 mm.

2. The tracer projectile according to claim 1 , wherein the elongate outer sheath is configured to be attached to a case.

3. The tracer projectile according to claim 2 , wherein the case includes brass.

4. The tracer projectile according to claim 1 , wherein the elongate outer sheath is selected from copper, steel, a copper steel laminate, or alloys thereof.

5. The tracer projectile according to claim 1 , wherein the elongate outer sheath includes a metal laminate.

6. The tracer projectile according to claim 1 , wherein the inner core includes a hardened tip.

7. The tracer projectile according to claim 1 , further comprising the at least one consolidated energetic material, wherein the at least one consolidated energetic material includes a quantity of pyrotechnic material, which is ignitable by a thermal output of a gun propellant.

8. The tracer projectile according to claim 1 , wherein the elongate outer sheath has a mean wall thickness variation of 0.02 mm or less.

9. A tracer projectile comprising:
an inner core; and
an elongate outer sheath, the elongate outer sheath encapsulating the inner core and extending rearwardly of the inner core to provide a cavity for receiving at least one consolidated energetic material, wherein the elongate outer sheath has a mean wall thickness variation of 0.02 mm or less.

10. The tracer projectile according to claim 9 , wherein the elongate outer sheath is configured to be attached to a case.

11. The tracer projectile according to claim 10 , wherein the case includes brass.

12. The tracer projectile according to claim 9 , wherein the elongate outer sheath is selected from copper, steel, a copper steel laminate, or alloys thereof.

13. The tracer projectile according to claim 9 , wherein the elongate outer sheath includes a metal laminate.

14. The tracer projectile according to claim 9 , wherein the inner core includes a hardened tip.

15. The tracer projectile according to claim 9 , further comprising the at least one consolidated energetic material, wherein the at least one consolidated energetic material includes a quantity of pyrotechnic material, which is ignitable by a thermal output of a gun propellant.
