Abstract

The Broadhead-Bullet is a new type of sub-sonic hunting projectile combining capabilities of an expandable broad head arrowhead with that of a firearm-fired projectile. The Broadhead-Bullet is for use in shorter ranges akin to shotgun slug ranges but is able to utilize the cost effectiveness, utility, and ease of use of existing firearms.

Claims

1. A new type of sub-sonic firearm projectile for use in a smoothbore barrel firearm comprising:

a. an elongated jacket surrounding and encasing an elongated core element, said elongated core element material has a greater density than said elongated jacket material, both said elongated core element and said elongated jacket compose a shaft;

b. a penetrating tip at a fore end of said elongated jacket whereby said penetrating tip initiates the penetration of said firearm projectile into target material;

c. two pivoting blades attached to a pin at a rear portion of said shaft, each of said pivoting blades are able to pivot independently on said pin;

d. a pivot blade stop located at the rear portion of said pivoting blade whereby said pivot blade stop creates a nodule out from said pivoting blade;

e. at least one shaft blade stop located near a aft portion of said shaft, said pivot blade stop terminates the deployment of said pivoting blade when said pivot blade stop contacts said shaft blade stop; and

f. a fin unit encasing the aft portion of both said pivoting blades and said shaft, said fin unit is releasable from the projectile when said pivoting blades deploy; and

g. a pin support, said pin support is attached to said core element and said pin whereby said pin support retains said pin to said core element.

2. The projectile from claim 1 further including a wad whereby said wad encases the projectile, said wad is releasable from the firearm projectile when the projectile exits the firearm barrel.

3. The projectile from claim 2 further including a shot shell containing a powder charge, said wad, and said sub-sonic firearm projectile.

4. The projectile from claim 1 further including at least one pivoting blade sabot affixed to the fore portion of each said pivoting blade whereby said pivoting blade sabots resist said pivoting blade from penetrating said target material when said pivoting blade is in the stowed position and whereby said pivoting blade sabot is releasable from said pivoting blade when said pivoting blade is in the deployed position.

5. The projectile from claim 4 further including a wad whereby said wad encases the projectile, said wad is releasable from the firearm projectile when the projectile exits the firearm barrel.

6. The projectile from claim 5 further including a shot shell containing a powder charge, said wad, and said sub-sonic firearm projectile.

7. A new type of sub-sonic firearm projectile for use in a smoothbore barrel firearm comprising:

a. an elongated jacket surrounding and encasing an elongated core element, said elongated core element material has a greater density than said elongated jacket material, both said elongated core element and said elongated jacket compose a shaft;

b. a penetrating tip at a fore end of said elongated jacket whereby said penetrating tip initiates the penetration of said firearm projectile into target material;

c. two pivoting blades attached to a pin at a rear portion of said shaft, each of said pivoting blades are able to pivot independently on said pin;

d. at least one shaft blade stop located aft of said pin, said pivot blade stop terminates the deployment of said pivoting blade when a spine of said pivot blade contacts said shaft blade stop; and

e. a fin-set encasing the aft portion of both said pivoting blades and said shaft, said fin-set is releasable from the projectile when said pivoting blades deploy; and

f. a pin support, said pin support is attached to said core element and said pin whereby said pin support retains said pin to said core element.

8. The projectile from claim 7 further including a wad whereby said wad encases the projectile, said wad is releasable from the firearm projectile when the projectile exits the firearm barrel.

9. The projectile from claim 8 further including a shot shell containing a powder charge, said wad, and said sub-sonic firearm projectile.

10. The projectile from claim 7 further including at least one pivoting blade sabot affixed to the fore portion of each said pivoting blade whereby said pivoting blade sabots resist said pivoting blade from penetrating said target material when said pivoting blade is in the stowed position and whereby said pivoting blade sabot is releasable from said pivoting blade when said pivoting blade is in the deployed position.

11. The projectile from claim 10 further including a wad whereby said wad encases the projectile, said wad is releasable from the firearm projectile when the projectile exits the firearm barrel.

12. The projectile from claim 11 further including a shot shell containing a powder charge, said wad, and said sub-sonic firearm projectile.
