     BACKGROUND OF INVENTION 
     1. Field of Invention 
     This invention relates to firearm projectiles, more specifically a firearm projectile that combines the functionality of a retractable broad head arrowhead with that of a shotgun shell intended for use with smoothbore shotguns of a specific caliber. 
     Objects and Advantages 
     The advantages of the Broadhead Bullet are as follows:
         To produce a firearm fired projectile that does not rely upon a rifled barrel for stabilization but rather in flight stabilization dependant upon airflow through its own construction and design.   To produce a sub-sonic firearm projectile that produces a much smaller noise signature than traditional super-sonic firearm projectiles for discrete hunting.   To produce a low kinetic energy firearm projectile for use in a smoothbore firearm that can successfully be use for hunting large game such as deer and elk.   For the circular sabot Broadhead Bullet, to produce a firearm fired projectile with a sabot that separates into at least two pieces upon impact and does not release until the projectile enters the target. This feature eliminates the destabilizing force associated with a sabot that releases in mid-flight and thus necessitates the projectile to be dependant upon centrifugal force for stabilization.   For the blade sabot Broadhead Bullet to produce a projectile for use with a smoothbore barrel, the Bullet to utilize four separate sabots each attached to an outside edge of blade. The sabots guide the pivoting blades into deployment stage and eject from the blades as the Bullet enters the target medium.   To produce a firearm projectile that mimics the performance of a broad head arrow fired from a compound bow.   To produce an expandable broad head projectile that creates a wound channel that is significantly larger than conventional broad heads on the market.   To create a bow hunting experience but with a firearm rather than expensive and difficult to use compound bows.   To produce a low kinetic energy subsonic hunting round that can be used in a smoothbore barreled firearm that would function within the firearm&#39;s action, as would ammunition for the same currently on the consumer market without modification to the function of the firearm.   To produce a sabot projectile that does not rely upon rifled barrels and centrifugal force for the projectiles stabilization.       

     2. Prior Art 
     The use of projectiles for big game hunting has been a unique method of hunting for mankind since the beginning written history. Mankind&#39;s ingenuity has perfected the firearm projectile into a highly effective hunting tool, specifically discussed here are the methods of hunting utilizing a bow and arrow and also that of the firearm and bullet. Both methods deliver a greatly enhanced method of harvesting meat via hunting and both methods offer their own advantages and disadvantages when compare to the other method of hunting discussed here. Unfortunately neither method it compatible with each other, both methods needs to be immersed within its own discipline with both the strategy and with equipment used to hunt. There have been attempts in the past to incorporate the advantages of both methods of hunting, bow and arrow and gun and bullet, but all have failed to bring a significantly superior product to the consumer market as their designs lack functionality, are too costly, do not perform well, or just plain do not work. The following are descriptions of prior art and discussions as to why these products have not been successful. 
     U.S. Pat. No. 1,318,858 was issued to John Frick for an expansible projectile for use in firearms and the like. Frick&#39;s invention has “outwardly projecting arms or cutting blades which are automatically positioned either due to the force of explosion or by the impact of the projectile against an object.” Unfortunately Frick&#39;s invention utilizes a complex arrangement to deploy his blades including a plunger. This construction and operation of his expansible projectile make it expensive and too difficult to implement in a practical manner. The plunger style orientation for deploying the blades is also not reliable, as any variation of impact may not activate the plunger correctly. Frick&#39;s projectile also does not utilize a sabot to protect his blade while traveling the length of the firearm barrel thus allowing for destabilizing forces to disrupt the intended trajectory. The present invention is intended for use in a firearm with a smoothbore barrel such as a 12-gauge shotgun. The Broadhead Bullet relies upon a sabot or several blade mounted sabots to accurately guide it though the length of the firearm barrel. 
     U.S. Pat. No. 2,661,694 was issued to James Allen and William Cantrell for the Spreader Panel Bullet that “spread laterally upon impact with an object”. As with Frick&#39;s invention the Spreader Panel Bullet does not incorporate a sabot to encase the projectile thus necessitating the blades and its supporting mechanisms to be encase within the projectile. This configuration is too complicated and expensive for the projectile to be except in specialty situations. The blades also are not connected to the projectile and only deploy in a forward swept position thus severely hindering its damaging potential, as this design would quickly slow the projectile as it enters the target medium. The blades would be subject to ejection from the projectile causing unpredictable performance. The supporting mechanisms for deploying the blades are complicated and therefore would be expensive and difficult to implement. The present invention utilizes a much simpler and more effective design and would thus be less expensive and yield better performance. 
     U.S. Pat. No. 5,078,407 was issued to Marvin Carlston for his Expandable Blade, Composite Plastic, and Broadhead Hunting Arrow Tip. Carlston here describes the use of “rotatable blades which are trunnion mounted securely in the body of the tip, and which are designed to be partially exposed while in flight”. Carlston describes the function of the blades as being able to “rotate into an expanded position upon impact” and “the blades are mounted in a forward position with the tips of the blades protruding outside of the tip body”. Carlston&#39;s design is one of simplicity and functionality and has been proven successful in the marketplace. Carlston&#39;s invention however is designed for bow hunting and is not for use with firearms, therefore it does not have any relevance to the present invention. 
     U.S. Pat. No. 6,240,849 was awarded to Christopher Holler for the Projectile with Expanding Members. Holler&#39;s invention has “open-biased arm members” that are “compressed into a restrained position” before firing the bullet. When the bullet is fired “the arms extend to the unrestrained position” which then catch the target material and slow the projectile down. Holler&#39;s invention is for a projectile suited for use in a rifled barrel and not a smooth bore shotgun as it relies upon centrifugal force for stabilization. Also his arms extend when the projectile is fired and not upon impact thus creating a massive amount of drag upon the projectile thus making it grossly inefficient as a projectile. Holler&#39;s projectile unfortunately may not be a feasible working projectile as it has many lacking characteristics that prevent it from becoming a workable firearm projectile. 
     U.S. Pat. No. 7,178,462 was awarded to Beasley for the Projectile with Members that Deploy Upon Impact. Beasley&#39;s projectile relies upon a “nose piece that shears off upon impact with the target, causing the nose piece to be pushed inside the projectile”. The “nose piece pushes on members that deploy outwardly and lock into place, thereby greatly increasing the damage done to the target”. Beasley&#39;s invention, much like Holler&#39;s, is a projectile intended for use within a rifled barrel and not a smoothbore barrel as it relies upon centrifugal force for stabilization of the projectile. Beasley&#39;s members or blades reside inside of the projectile and require an intricate mechanical arrangement for the deployment of the blades. Also the members or blades are unfortunately restricted in size due to the stowing of the blades within the bullet thus the members are also severely restricted in the amount of damage the can inflict upon the target. In all Beasley&#39;s projectile is complicated in use and construction and offers minimal advantage for the members to inflict damage therefore the concept has minimal value for its intended purpose.

     DESCRIPTION 
     Preferred Embodiment FIGS.  1 - 11   
     The Broadhead Bullet assembly  2  is illustrated in  FIGS. 1-11 . The Broadhead Bullet is intended to function within a 12-gauge shotgun with a smooth bore barrel, as would current 12-gauge shot shells for smooth bore barrels on the consumer market today.  FIG. 1-4  details the Broadhead Bullet assembly  2  in the in flight mode with the pivoting blades  6  in their closed position. Here the pivoting blades  6  are rotated forward on the blades  6  blade pivot  12  and the blade edges  30  rests on or near the Broadhead Bullets  2  shaft  4  while pivoting blade sabots  28  reside at the forward most position of the blades  6 . The pivoting blades  6  front tips are centralized at the front of the assembly such that the tips are in alignment with the central horizontal axis of the shaft  4 . The rear end of the pivoting blades  6  are attached to the blade pivot  12  where both pivoting blades  6  reside side by side on the blade pivot  12 . This construction allows for a slight angular bias between the rear and front ends of the pivoting blades  6 . Fixed Blades  8  reside at 90 degrees from either of the pivoting blades  6  position on shaft  4 . 
     Stationary blade sabots  22  are attached to the outer most edge of the stationary blades  8  and are constructed from a plastic like material that will not damage the inside surface of the firearm barrel as well as to provide a contact surface with the characteristic of having less friction than would the stationary blade produce against the firearm barrel. Pivoting blade sabots  28  are attached to the outer and forward most position of the pivoting blades  6  and are also constructed from a plastic like material that will not damage the inside surface of the firearm barrel as well as to provide a contact surface with the characteristic of having less friction than would the pivoting blades produce against the firearm barrel. Both the stationary blade sabots  22  and pivoting blade sabots  28  provide a barrier between both the stationary blades  8  and the pivoting blades  6  and the inside surface of the firearm barrel such that the assembly  2  will not experience any sizable gap between the sabots  22 ,  28  and the firearm barrel thus eliminating any vibrational disruption in the trajectory of the assembly  2 . 
       FIG. 5  shows a side view and  FIG. 6  shows a front view of the Broadhead Bullet with the pivoting blades  6  in full deployment stage. Here pivoting blade edges  30  now face forward of the Broadhead Bullet  2 . The pivoting blades  6  at the blade pivot  12  are positioned side by side thus aligning the bases of the pivoting blades  6  off center from the central horizontal axis of the shaft  4 . This construction allows for a slight angular bias between the rear and front ends of the pivoting blades. The pivoting blades  6  in the fully deployed stage rest against blade stop  14  in such a way the blade stop  14  stops the pivoting deployment action of the pivoting blades  6  as well as to provide a strengthened rest to support the pivoting blades  6 . 
       FIG. 7  shows the Broadhead Bullet  2  inside of a shotgun shell  38 , as it would be before being shot. The shotgun shell  38  here is semi transparent to better illustrate the construction of the Broadhead Bullet  2  within the shot shell. Here the shell  38  contains powder charge  40 , wad-sabot  20 , and the Broadhead Bullet  2 . 
       FIG. 8  shows an exploded view of the Broadhead Bullet  2  with the shot shell  38 , powder charge  40 , Wad-sabot  20 , and Broadhead Bullet  2 . 
       FIG. 9  shows a cut-a-way view of a shotgun barrel  44  with the Broadhead Bullet assembly  2  and wad-sabot  20 , as they would be after firing the round from the shotgun shell  38 . Here the stationary blade sabots  22 , pivoting blade sabots  28 , and the wad-sabot  20  are all connected to the Broadhead Bullet  2  and are in contact with the gun barrel  44  in a manner that will not allow the pivoting blades  6  and stationary blades  8  to contact the gun barrel  44 . 
       FIG. 10  shows the Broadhead Bullet  2  in the early stages of striking the target material  42 , the pivoting blade sabots  28  are in contact with the material  42  as well as the stationary blades  2  and stationary blade scoop  10 . The pivoting blades  6  are in the early deployment stage. 
       FIG. 11  shows the Broadhead Bullet  2  as the entire assembly enters the target material  42  minus the pivoting blade sabots  28  and stationary blade sabots  22  which are ejected from the pivoting blades  6  and stationary blades  8  respectively. The stationary blades  8 , pivoting blades  6 , and stationary blade scoop  10  cut a path through the target material  42  as the Broadhead Bullet  2  travels through the target material  42 . 
     Operation of Invention:  FIGS. 1-11   
     The Broadhead Bullet assembly  2  is illustrated in  FIGS. 1-11 . The Broadhead Bullet is intended to function within a 12-gauge shotgun with a smoothbore barrel, as would current 12-gauge shotgun shells for smooth bore barrels on the consumer market today.  FIG. 1-4  details the Broadhead Bullet assembly  2  in the in flight with the pivoting blades  6  in their closed position. Here the pivoting blades  6  are rotated forward on the blades  6  blade pivot  12  and the blade edges  30  rests on or near shaft  4  while pivoting blade sabots  28  reside at the forward most position of the blades  6 . The pivoting blades  6  front tips are positioned at the front of the assembly  2  such that the tips are in alignment with the central horizontal axis of the shaft  4 . The rear end of the pivoting blades  6  are attached to the blade pivot  12  where both pivoting blades  6  reside side by side on the blade pivot  12 . This construction allows for a slight angular bias between the rear and front ends of the pivoting blades  6 . This angular bias will impart a rotational force to the Broadhead Bullet  2  during its trajectory by directing the air around the pivoting blades  6  thus imparting a resistance to the Bullet  2  to spin around its central horizontal axis. This spin will create a more stable flight trajectory for the Broadhead Bullet  2  as would the spin a traditional bullet fired from a rifled barrel would stabilize the round. Fixed Blades  8  reside at 90 degrees from either of the pivoting blades  6  position on shaft  4  and may also have an angular bias such as to impart a rotational force to the Broadhead Bullet  2 . 
     Stationary blade sabots  22  are attached to the outer most edge of the stationary blades  8  and are constructed from a plastic like material that will not damage the inside surface of the firearm barrel as well as to provide a contact surface with the characteristic of having less friction than would the stationary blade produce against the firearm barrel. Pivoting blade sabots  28  are attached to the outer and forward most position of the pivoting blade  6  and are also constructed from a plastic like material that will not damage the inside surface of the firearm barrel as well as to provide a contact surface with the characteristic of having less friction than would the pivoting blades produce against the firearm barrel. Pivoting blade sabots  28  may have an airfoil design to impart a low drag characteristic or an airflow bias to the pivoting blades  6  thus aiding the Broadhead Bullet  2  to maintain its velocity and rotational spin. 
     Both the stationary blade sabots  22  and pivoting blade sabots  28  provide a barrier between both the stationary blades  8  and the pivoting blades  6  respectfully and the inside surface of the firearm barrel such that the Broadhead Bullet  2  will not experience any sizable gap between the sabots  22 ,  28  and the gun barrel  44  thus eliminating any vibration disruption at it travels through the gun barrel  44 . 
       FIG. 7  shows the Broadhead Bullet  2  inside of a shotgun shell  38 , as it would be before being shot. The shotgun shell  38  here is semi transparent to better illustrate the construction of the Broadhead Bullet  2  within the shotgun shell  38 . Here the shell  38  contains powder charge  40 , wad-sabot  20 , and the Broadhead Bullet  2 . 
       FIG. 8  shows an exploded view of the Broadhead Bullet  2  with the shotgun shell  38 , powder charge  40 , Wad-sabot  20 , and Broadhead Bullet  2 . 
       FIG. 9  shows a cut-a-way view of a gun barrel  44  with the Broadhead Bullet assembly  2  and wad-sabot  20 , as they would be after firing the round from the shotgun shell  38 . Here the stationary blade sabots  22 , pivoting blade sabots  28 , and the wad-sabot  20  are all connected to the Broadhead Bullet  2  and are in contact with the gun barrel  44  in a manner that will not allow the pivoting blades  6  and stationary blades  8  to contact the gun barrel  44 . 
     When the Broadhead Bullet  2  is fired, the primer ignites the powder charge  40  after the primer is struck by the guns firing pin. As the powder  40  burns the expanding gasses produced pushes the wad-sabot  20  against the Broadhead Bullet  2 , which is in turn pushed out of the shell  38  and into the gun barrel  44 . During this stage the wad-sabot  20 , pivoting blade sabots  28 , and stationary blade sabots  22  guides the Broadhead Bullet  2  through the firearm barrel  44  providing a stabilizing travel while preventing the pivoting blades  6  and stationary blades  8  from contacting the gun barrel  44 . As the Broadhead Bullet  2  exits the firearm barrel  44  the wad-sabot  20  is ejected from the Broadhead bullet  2  leaving only the Bullet  2 , pivoting blade sabots  28 , and stationary blade sabots  22  on its intended trajectory towards the target. 
     The Broadhead Bullet  2  here mimics the trajectory of an arrow fired from a high-powered compound bow, depending on the size of the powder charge  40 . This intended trajectory for the Broadhead Bullet  2  thus allows for it to be used in areas where the type of projectile is limited to short ranges due to high-density area hunting. The Broadhead Bullet  2  is intended for use in one of the most popular firearms, the 12-gauge shotgun, without modifications to the shotgun. A sighting system specifically calibrated to the trajectory of the Broadhead Bullet  2  may be incorporated to compensate for the shortened travel of the Bullet  2 . 
       FIG. 10  shows the Broadhead Bullet  2  in the early stages of striking the target medium  42 , the pivoting blade sabots  28  are in contact with the medium  42  as well as the stationary blades  2  and stationary blade scoop  10 . As the shaft  4 , blade scoop  10 , and stationary blades  8  travel through the target material  42  the pivoting blade sabots  28  catch the target material  42  preventing the pivoting blades  6  from penetrating the target material  42 . The pivoting blade sabots  28  slide along the external surface of the target material and away from the central horizontal axis of the shaft  4 , which deploys the pivoting blades  6  into the open position.  FIG. 10  shows the pivoting blades  6  in the early stages of pivoting blade  6  deployment.  FIG. 11  shows the Broadhead Bullet  2  as the entire assembly has entered the target material  42  minus the pivoting blade sabots  28  and stationary blade sabots  22  which are ejected from the pivoting blades  6  and stationary blades  8  respectively. The pivoting blades  6  have fully deployed and rest against blade stop  14  in such a way the blade stop  14  stops the pivoting deployment action of the pivoting blades  6  as well as to provide a strengthened rest to support the pivoting blades  6 . The stationary blades  8 , pivoting blades  6 , and stationary blade scoop  10  cut a path through the target medium  44  as the Broadhead Bullet  2  travels through the target material  42 . 
     DESCRIPTION 
     Alternate Embodiment FIGS.  12 - 20   
     The Broadhead Bullet alternate embodiment  34  is illustrated in  FIGS. 12-20 . The Broadhead Bullet alternate embodiment  34  is intended to function within a 12-gauge shotgun with a smooth bore barrel, as would current 12-gauge shot shells for smooth bore barrels on the consumer market today.  FIGS. 12-15  details the Broadhead Bullet alternate  34  in the in flight mode with the pivoting blades  6  in their closed position. Here the pivoting blades  6  are rotated forward on the blades  6  blade pivot  12  and the blade edges  30  rest on or near the shaft  4 . Pivoting blade tips  18  are centralized at the front of the Broadhead Bullet alternate  34  such that the tips  18  are in alignment with the central horizontal axis of the shaft  4 . The rear end of the pivoting blades  6  are attached to the blade pivot  12  where both pivoting blades  6  reside side by side on the blade pivot  12 . This construction allows for a slight angular bias between the rear and front ends of the pivoting blades  6 . Fixed Blades  8  reside at 90 degrees from either of the pivoting blades  6  position on shaft  4 . 
     The circular sabot  26  is constructed from two separate and identical pieces and is attached to the pivoting blades sabot recess  32  portion of the pivoting blades  6  and contact the stationary blades  8  such that the stationary blades  8  provide structural support to the sabot  26  during firing and in flight. The circular sabot  26  pieces are constructed from a plastic like material that will not damage the inside surface of the gun barrel  44  as well as to provide a contact surface with the characteristic of having less friction than would the stationary  8  and pivoting  6  blades would produce against the gun barrel  44 . The circular sabot  26  and wad-sabot  20  provides a barrier between both the stationary blades  8  and the pivoting blades  6  and the inside surface of the gun barrel  44  such that the alternate assembly  34  will not experience any sizable gap between the sabot  26 , wad-sabot-sabot  20  and the firearm barrel  44  thus eliminating any vibration disruption in the trajectory of the Broadhead Bullet alternate  34 . The circular sabot  26  parts are ejected from the pivoting blades sabot recess  32  portion of the pivoting blades  6  as the Broadhead Bullet alternate  34  travels through the target material  42 . 
       FIG. 16  shows the Broadhead Bullet alternate  34  with the circular sabot  26  and wad-sabot-sabot  20  inside of a shot shell  38 , as it would be before being shot. The shot shell  38  here is semi transparent to better illustrate the construction of the Broadhead Bullet alternate  34  within the shot shell  38 . Here the shell  38  contains powder charge  40 , wad-sabot  20 , and the Broadhead Bullet alternate  34  with the circular sabot  26 . 
       FIG. 17  shows an exploded view of the Broadhead Bullet alternate  34  with circular sabot  26 , powder charge  40 , wad-sabot  20 , and Broadhead Bullet alternate  34  all outside the confines of the shot shell  38 . 
       FIG. 18  shows a cut-a-way view of a shotgun barrel  44  with the Broadhead Bullet alternate  34  with circular sabot  26 , and wad-sabot  20  as they would be inside of a smoothbore shotgun barrel after being fired. Here the circular sabot  26  and the wad-sabot  20  are all connected to the Broadhead Bullet alternate  34  and are also in contact with the gun barrel  44  in a manner that will not allow the pivoting blades  6  and stationary blades  8  of the Broadhead Bullet alternate  34  to contact the gun barrel  44 . The sabot-wad  20  is shown carrying the rear portion and the circular sabot  26  carrying the front portion of the Broadhead Bullet alternate  34  through the gun barrel  44  thus giving the alternate  34  maximum stability as it travels through the gun barrel  44 . 
       FIG. 19  shows the Broadhead Bullet alternate  34  during the early stages of the pivoting blades  6  deploying with the pivoting blade tips  18  of the pivoting blades  6  in contact with the medium  42  as well as the stationary blades  8  and stationary blade scoop  10 . The pivoting blades  6  are being forced into deployed position by the target medium  42  as the Broadhead Bullet alternate  34  begins to travel through the target medium  42 . The pivoting blades  6  here also pivot on the blade pivot  12  to which they are attached, the blade stop  14  here has not yet contacted the pivoting blades  6 . The circular sabot  26  here has separated into two pieces, each piece still attached to an individual pivoting blade  6 . 
       FIG. 20  shows the Broadhead Bullet alternate  34  as it is entirely inside the target medium  42 . Here the pivoting blades  6  are in the fully deployed position, the rear end base of each pivoting blade  6  resting against the blade stop  14  which support the pivoting blades  6  as the Broadhead Bullet alternate  34  travels through the target medium  42 . The two circular sabot  26  parts here have been ejected from the pivoting blades  6  by and remain outside of the target medium  42 . The stationary blades  8 , pivoting blades  6 , and stationary blade scoop  10  cut a path through the target medium  42  as the Broadhead Bullet alternate  34  travels through the target medium  42 . 
     OPERATION OF INVENTION 
     Alternate Embodiment: FIGS.  12 - 20   
     The Broadhead Bullet alternate  34  embodiment is illustrated in  FIGS. 12-20 . The Broadhead Bullet alternate  34  is intended to function within a 12 Gauge shotgun with a smooth bore barrel, as would current 12 Gauge shot shells for smooth bore barrels on the consumer market today.  FIG. 12-15  details the Broadhead Bullet alternate  34  in the in flight with the pivoting blades  6  in their closed position. Here the pivoting blades  6  are rotated forward on the blades  6  blade pivot  12  and the blade edges  30  rest on or near shaft  4 . The pivoting blade tips  18  are positioned at the front of the Broadhead Bullet alternate assembly  34  such that the tips  18  are in alignment with the central horizontal axis of the shaft  4 . The rear portions of the pivoting blades  6  are attached to the blade pivot  12  where both pivoting blades  6  reside side by side along the horizontal axis of the blade pivot  12 . This construction allows for a slight angular bias between the rear portions of the pivoting blades  6  and pivoting blade tips  18 . This angular bias will impart a rotational force to the Broadhead Bullet alternate  34  during its trajectory by directing the air around the pivoting blades  6  thus imparting a resistance to the Broadhead Bullet alternate  34  to spin around its central horizontal axis. This spin will create a more stable flight trajectory for the Broadhead Bullet alternate  34  as would the spin a traditional bullet fired from a rifled barrel would stabilize the round. Fixed Blades  8  reside at 90 degrees from either of the pivoting blades  6  position on shaft  4  and may also have an angular bias such as to impart a rotational force to the Broadhead Bullet alternate  34 . 
     The circular sabot  26  is constructed from two separate and identical pieces that are attached to the outer most edge of the pivoting blades  6  and contact the stationary blades  8  such that the stationary blades  8  provide structural support to the sabot  26  during flight. The circular sabot  26  pieces are constructed from a plastic like material that will not damage the inside surface of the firearm barrel  44  as well as to provide a contact surface with the characteristic of having less friction than would the pivoting blades  6  and stationary blade  8  produce against the firearm barrel  44 . The circular sabot  26  provides a barrier between both the stationary blades  8  and the pivoting blades  6  and the inside surface of the firearm barrel such that the Broadhead Bullet  2  will not experience any sizable gap between the sabot  26  and the firearm barrel thus eliminating any vibration disruption as it travels through the gun barrel  44 . The circular sabot  26  may have an airfoil design to impart a low drag characteristic while the Broadhead Bullet alternate  34  is in flight while also creating a stabilizing force onto the Broadhead Bullet alternate  34  such that the trajectory of the Bullet alternate  34  will be more true to its intended trajectory and less susceptible to outside disrupting forces. 
       FIG. 16  shows the Broadhead Bullet  2  inside of a shot shell  38 , as it would be before being shot. The shot shell  38  here is semi transparent to better illustrate the construction of the Broadhead Bullet alternate  34  within the shot shell  38 . Here the shell  38  contains powder charge  40 , wad-sabot  20 , and the Broadhead Bullet alternate embodiment  34 . 
       FIG. 17  shows an exploded view of the Broadhead Bullet alternate  34  with the shot shell  38 , powder charge  40 , Wad-sabot  20 , and Broadhead Bullet alternate  34 . 
       FIG. 18  shows a cut-a-way view of a shotgun barrel  44  with the Broadhead Bullet alternate  34  and the wad-sabot  20 , as they would be after firing the round from the shotgun shell  38 . Here the circular sabot  26  and the wad-sabot  20  are connected to the Broadhead Bullet alternate  34  and are also in contact with the gun barrel  44  in a manner that will not allow the pivoting blades  6  and stationary blades  8  to contact the gun barrel  44 . Pivoting blade sabot recess  32 , shown in  FIG. 20 , prevent the circular sabot  26  from sliding reward of the Broadhead Bullet alternate  32  during its travel through the gun barrel  44 . When the Broadhead Bullet alternate  34  is fired, the primer ignites the powder charge  40  after the primer is struck by the guns firing pin. As the powder  40  burns the expanding gasses produced pushes the wad-sabot  20  against the Broadhead Bullet alternate  34 , which is in turn pushed out of the shell  38  and into the firearms barrel  44 . During this stage the wad-sabot  20  and circular sabot  26  guides the Broadhead Bullet alternate  34  through the firearm barrel  44  providing stabilized travel while preventing the pivoting blades  6  and stationary blades  8  from contacting the gun barrel  44 . As the Broadhead Bullet alternate  34  exits the firearm barrel  44  the wad-sabot  20  is ejected rearward from the Broadhead bullet alternate  34  leaving only the Bullet alternate  34  and circular sabot  26  on its intended trajectory towards the target. 
     The Broadhead Bullet Sabot assembly  34  here mimics the trajectory of an arrow fired from a high-powered compound bow, depending on the size of the powder charge  40 . This intended trajectory for the Broadhead Bullet alternate  34  thus allows for it to be used in areas where the type of projectile is limited to short ranges due to high-density area hunting. The Broadhead Bullet Sabot assembly  34  is also intended for use in one of the most popular firearms, the 12 Gauge shotgun, without modifications to the shotgun. A sighting system specifically calibrated to the trajectory of the Broadhead Bullet alternate  34  may be incorporated to compensate for the shortened travel of the Bullet alternate  34 . 
       FIG. 19  shows the Broadhead Bullet alternate  34  in the early stages of striking the target medium  42 , the pivoting blade tips  18  are in contact with the medium  42  as well as the stationary blades  2  and stationary blade scoop  10 . As the shaft  4  travels through the target medium the pivoting blade tips  18  catch the target material  42  preventing the pivoting blades  6  from penetrating the target material  42 . The pivoting blade tips  18  slide along the external surface of the target material and away from the central horizontal axis of the shaft  4 , which deploys the pivoting blades  6  into a semi deployed stage. The circular sabot  26  is constructed from two identical pieces that fit together while the Broadhead Bullet alternate  34  is inside of the shot shell  38  and while in flight. The circular sabot  26  creates a stabilizing effect onto the Broadhead Bullet alternate  34  while in flight as well as to act as a sabot between the Bullets alternate  34  and the gun barrel  44 . Here in  FIG. 19  the two pieces of the circular sabot  26  separate as the pivoting blades  6  achieve semi deployed stage. Here the circular sabot  26  pieces remain attached to the pivoting blades  6  in a releasable manner that will be shown in  FIG. 20 . 
       FIG. 20  shows the Broadhead Bullet alternate  34  as the entire assembly has entered the target medium  42  minus the circular sabot  26  pieces, which are ejected from the pivoting blade sabot recess  32  portions of the pivoting blades  6 . The pivoting blades  6  have achieved the fully deployed position and rest against blade stop  14  in such a way the blade stop  14  stops the pivoting deployment action of the pivoting blades  6  as well as to provide a strengthened rest to support the pivoting blades  6 . The stationary blades  8 , pivoting blades  6 , and stationary blade scoop  10  cut a path through the target medium  44  as the Broadhead Bullet alternate  34  travels through the target medium  42 .
