Lead attached sabot slug
View Patent ↗Disclosed is sabot and a firearm round for a firearm. The sabot includes a compression section defining a payload receiving chamber. The payload chamber receives a slug to form the firearm round. Additionally, the sabot includes a solid section connected to the compression section. The solid section can include a powder cup section for sealing ignition gasses. Typically, the sabot is formed from a high density polyethylene.
1. A firearm round having a longitudinal axis, comprising:
a polymeric sabot, the sabot comprising:
a receiving chamber at a front of the sabot, the receiving chamber defined in part by a plurality of alternating interior and exterior ridges, wherein the alternating interior ridges are spaced from one another along the longitudinal axis; and
a metallic slug disposed within the receiving chamber wherein the receiving chamber is adapted to at least partially collapse along a direction of the longitudinal axis upon firing.
2. The firearm round of claim 1 , wherein the slug abuts at least one of the alternating interior ridges.
3. The firearm round of claim 1 , wherein the slug abuts a front edge of the front of the sabot.
4. The firearm round of claim 1 , wherein the sabot is axisymmetric about the longitudinal axis.
5. The firearm round of claim 1 , wherein the sabot further comprises a solid section at a rear of the sabot.
6. The firearm round of claim 5 , wherein the sabot further comprises a post extending from the solid section toward the front of the sabot.
7. The firearm round of claim 6 , wherein the slug comprises a stem defining a chamber adapted to receive the post of the sabot.
8. The firearm round of claim 5 , wherein the solid section comprises a powder cup section at the rear of the sabot.
9. The firearm round of claim 1 , wherein the sabot further comprises a locking ring engaged with the slug.
10. The firearm round of claim 9 , wherein the locking ring is adjacent to a front edge of the front of the sabot.
11. The firearm round of claim 1 , wherein the slug has a generally annular shape and a rear edge of the slug abuts a front edge of the front of the sabot.
12. The firearm round of claim 1 , wherein the slug comprises a nose, a driving band adjacent the nose and a stem connected to the driving band, and wherein the driving band is adapted to engage rifling of a barrel of a rifled firearm.
13. The firearm round of claim 12 , wherein the driving band has a length less than about 25% of an overall diameter of the firearm round.
14. The firearm round of claim 12 , wherein the stem has a diameter less than a diameter of the driving band.
15. The firearm round of claim 12 , wherein the nose includes a nose cavity at a front of the nose.
16. A firearm round having a longitudinal axis, comprising:
a polymeric sabot, the sabot comprising:
a receiving chamber at a front portion of the sabot, the receiving chamber defined in part by a plurality of alternating interior ridges, wherein the alternating interior ridges are spaced from one another along the longitudinal axis; and
a metallic slug disposed within the receiving chamber, the slug having a driving band abutting a front edge of the sabot, and a stem abutting at least one of the alternating interior ridges,
wherein the receiving chamber is adapted to at least partially collapse along a direction of the longitudinal axis upon firing.
17. The firearm round of claim 16 , wherein an exterior surface of the receiving chamber is defined in part by a plurality of exterior ridges spaced from one another along the longitudinal axis.
18. The firearm round of claim 1 , wherein the plurality of alternating interior and exterior ridges are annular.
19. The firearm round of claim 17 , wherein the plurality of alternating interior and exterior ridges are annular.
20. The firearm round of claim 17 , wherein the plurality of alternating interior and exterior ridges are annular and the interior ridges abut the metallic slug.
