Broadhead-bullet with sabot
First Claim
Patent Images
1. A new type of sub-sonic firearm projectile for use in a smoothbore barrel firearm comprising:
- a. a projectile shaft whereby said projectile shaft has a center of gravity biased towards the fore end of said projectile shaft;
b. a penetrating tip located at the fore end of said projectile shaft whereby said penetrating tip initiates the penetration of said firearm projectile into target material;
c. a blade support located at the aft end of said projectile shaft, said blade support is attached to said projectile shaft whereby said blade support retains pivoting blades to said projectile shaft;
d. two said pivoting blades attached to said blade support whereby each of said pivoting blades can pivot counter rotational to the opposing said pivoting blade on said blade support;
e. at least one shaft blade stop located at the aft end of said projectile shaft, said pivot blade stop terminates the deployment of said pivoting blade when a spine of said pivot blade contacts said shaft blade stop; and
f. a fin unit attached to the aft portion of said projectile whereby said fin unit creates a center of pressure biased towards the aft end of said projectile shaft, said fin unit is released from the projectile when said pivoting blades deploy.

Abstract
The Broadhead-Bullet and Sabot 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 and Sabot 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.

7. A new type of sub-sonic firearm projectile for use in a smoothbore barrel firearm comprising:
-
a. a projectile shaft whereby said projectile shaft has a center of gravity biased towards the fore end of said projectile shaft; and
whereby the aft portion of said projectile shaft has a compressive yield strength greater than peak pressure during propellant burning;b. a penetrating tip located at the fore end of said of said projectile shaft whereby said penetrating tip initiates the penetration of said firearm projectile into target material; c. a blade support located at the aft end of said projectile shaft, said blade support is attached to said projectile shaft whereby said blade support retains pivoting blades to said projectile shaft; d. two said pivoting blades attached to said blade support whereby each of said pivoting blades can pivot counter rotational to the opposing said pivoting blade on said blade support; e. at least one shaft blade stop located at the aft end of said projectile shaft, said pivot blade stop terminates the deployment of said pivoting blade when a spine of said pivot blade contacts said shaft blade stop; f. a fin unit attached to the aft portion of said projectile whereby said fin unit creates a center of pressure biased towards the aft end of said projectile shaft, said fin unit is released from the projectile when said pivoting blades deploy. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
