     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. 
     BACKGROUND OF INVENTION 
     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. 
     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 be used for hunting large game such as deer and elk.   To produce a firearm fired projectile with a finned stabilizer that releases from the projectile upon impact.   To produce an expandable broad head projectile that creates a wounding effect that is similar to conventional archery broad heads on the market.   To produce a firearm projectile for use in limited range projectile hunting areas as defined by hunting laws.   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 projectile that does not rely upon rifled barrels and centrifugal force for the projectiles stabilization.   To produce a firearm projectile for use in 12 gauge shotguns with less recoil than Foster slugs and Buckshot.   To produce a projectile with a 100-yard center of hold for the animals kill zone. No need for specialized optics for effective hunting within 100 yards.

     DESCRIPTION 
     Preferred Embodiment FIGS.  1 - 16   
       FIGS. 1 and 2  details the Broadhead-Bullet assembly  19  in flight. The Pivoting blades  7  here are in the stowed position, rotated forward onto the Shaft  1  on the Pin  5 . Pivoting blade edges  21  rests against the Broadhead-Bullet&#39;s  19  Shaft  1 . Blade sheaths  11  reside at the forward most position of the Blades  7  and are constructed from a durable material such as vinyl or similar plastic. Penetrating tip  3  resides at the frontal most portion of the Shaft  1 . Gouge troughs  29  are on the front portion of Shaft  1  and behind the forward most portion of Tip  3 . Both the Shaft  1  and Penetrating tip  3  here are constructed from an impact resistant material such as plastic and here consists of one continuous part. Core weight  13  here is constructed from a dense material such as lead or in the case of a lead free Broadhead-Bullet it is constructed from material with a high density quality such as steel or high-density concrete. The Shaft  1  and Penetrating tip  3  here are molded plastic surrounding and encasing the Core weight  13 . 
     The Pin  5  here is constructed from high tensile strength material such as steel and supports the Pivoting blades  7 . The Pin  5  is supported by Pin support  31 , which is constructed from a high tensile strength material such as steel and can have the configuration such as a collar or wire. Pin support  31  here is connected to both the Pin  5  and Core weight  13 . 
     Pivoting blade  7  have a Pivoting blade stop  8  located at the rear portion of the Blade  7  such that the Stop  8  creates a nodule out from the circular circumference shape of the Blade  7  portion surrounding the Pin  5 . When the Pivoting blade  7  is in the fully deployed position the Pivoting blade stop  8  contacts Shaft blade stop  15 , here constructed from the Shaft  1  material. Pivoting blade  7  in the fully deployed position have Pivoting blade edges  21  that face towards the Penetrating tip  3  portion of the Shaft  1 . 
     The Fin units  9  are located near the rearward portion of the Shaft  1  and consists of two pieces that when the Blades  7  are in the stowed position they combine to contain both the Shaft  1  and Blades  7 . The Fin units  9  separate into two separate pieces when the Pivoting blades  7  pivot into the deployed position. 
       FIGS. 7 and 9  are side views of the Broadhead-Bullet assembly  19  with the Pivoting blades  7  stowed position; the assembly  19  is contained within the Wad  17 .  FIGS. 8 and 10  are cross-sectional views from  FIGS. 7 and 9  respectively. Wad supports  18  are a portion of the Wad  17  that extends to the Shaft  1 . 
       FIG. 11  is a cross-sectional view of a Broadhead-Bullet assembly  19 , Wad  17 , and Powder Charge  35 , inside of a Shell  23 .  FIG. 12  details the exploded view of the Broadhead-Bullet assembly  19  further including the Shell  33 , Powder charge  35 , and the Wad  17 .  FIG. 13  is a cross-sectional view of a Broadhead-Bullet assembly  19  inside of a Wad  19 , both of which are inside of a Gun barrel  26 . 
       FIGS. 14-16  detail the Broadhead-Bullet  19  contacting the Target Material  37 .  FIG. 14  details the Broadhead-Bullet assembly 19  in flight before impacting the Target material  37 .  FIG. 15  details the Broadhead-Bullet  19  contacting the Target material  37 , the Pivoting blades  7  deploying and the Wad  9  separating. Penetrating tip  3  and Gouge troughs  29  initiates Target material  37  penetration.  FIG. 16  details the Broadhead-Bullet assembly  19  inside of the Target material  37 . Here the Pivoting Blades  7  are in fully deployed position, the Fin unit  9  halves and Blade sheathes  11  are ejected from the Pivoting blades  7 . The Broadhead-Bullet assembly  19  continues to travel through the Target material  37  with the Pivoting blades  7  cutting a wound channel through the Target material  37  until its kinetic energy is depleted. 
     Operation of Invention 
     Preferred Embodiment FIGS.  1 - 16   
       FIGS. 1-16  detail the Broadhead-Bullet assembly 19  construction and operation. The Broadhead-Bullet Shot Shell here is intended to function within a 12 Gauge shotgun with a smooth bore barrel, as would a 12 Gauge shot or slug shell would. The Powder charge  25 , Wad  17 , and the Broadhead-Bullet assembly  19  are all contained within the Shell  23  when the Broadhead-Bullet assembly  19  is in the pre-firing state. When the Broadhead-Bullet Shot Shell is fired from the firearm, the primer ignites the Powder charge  25  after the primer is struck by the firing pin. As the Powder  25  burns the expanding gasses produced pushes the Wad  17  against the Broadhead-Bullet  19 , which is in turn pushed out of the Shell  23  and into Gun barrel  26 . The Wad supports  18  maintain the circular profile of the Wad  17  as well as maintaining the true position of the Broadhead-Bullet  19  along the horizontal axis of the Gun barrel  26  while the Wad  17  and Broadhead-Bullet  19  travels through the Gun barrel  26 . The Wad  17 , when in the Gun barrel  26 , encases and protects the Broadhead-Bullet assembly  19  until it is ejected from the Gun barrel  26 , where the Wad  17  is ejected from the Broadhead-Bullet  19 . The purpose of the Wad  17  is to allow the Broadhead-Bullet assembly  19  to travel through the Gun barrel  26  with a tight tolerance and little friction thus giving the Broadhead-Bullet  19  the accuracy the barrel can create while the Broadhead-Bullet is in flight towards the target. 
     When the Pivoting blades  7  are in the stowed position the Pivoting blade edge  21  is in contact with the Shaft  1  and the two Fin unit  9  parts are in contact with each other to form a continuous Fin unit  9 . In this state the Broadhead Bullet assembly  19  is either encased by the Wad  17  or is in flight sans the Wad  17 . 
     While in flight the Fin unit  9  creates a pressure, via air flowing across the Fin unit  9 , creating fluid resistance that is directed downward onto the Pivoting blades  7 . This pressure is sufficient to maintain the Pivoting blades  7  stowed position during flight until the Broadhead-Bullet  19  either strikes the Target material  37  or achieves a zero velocity state. Fin unit support  10  maintains the desired shape of the Fin unit  9  when the halves are combined and until the Broadhead-Bullet  19  contacts the Target material  37  adding stability to the Broadhead-Bullet  19  during flight. 
     The Blade sheaths  11  have an air foil shape where the fluid resistance from the flow of air around Sheaths  11  would have a minimal value or less value than if the Broadhead-Bullet were to be sans the Sheaths  11 . The combined fluid pressure effect on the Sheaths  11  and the Fin unit  9 , as well as the forward position of the Core weight  13  would create a Center of Pressure rearward of the Center of Gravity therefore creating the conditions for a stable flying projectile. 
     The Broadhead-Bullet  19  would have a sub-sonic velocity of roughly 1000 ft/sec or 3 times the velocity compared to an arrow fired from a high-powered compound bow. This velocity would give the Broadhead Bullet assembly  19  an effective range of roughly 100 yards thus allowing for it to be used in areas limited to short ranges due to applicable hunting regulations. The trajectory of the Broadhead-Bullet  19  beyond 100 yards aggressively deteriorates. 
     As the Broadhead-Bullet assembly  19  strikes the Target material  37  the Blade sheaths  11  and the Penetrating tip  3  are the first portions of the Broadhead-Bullet  19  to contact the Target material  37 . As the Broadhead-Bullet  19  enters the Target material  37  the Gouge trough  29  of the Penetrating tip  3  forces the Target material  37  into the Blade sheaths  11  which in turn rotates the frontal portions of the Pivoting blades  7  outward from their stowed position, pivoting the Blades  7  on the Pin  5 . The Fin unit  9  halves separate as the Pivoting blades  7  deploy from the stowed position. As the Shaft  1  completely enters the Target material  37  the Pivoting Blades  7  have pivoted outward until the Blades  7  are in the fully deployed position. Here the Pivoting blade stop  8  on each Pivoting blade  7  have contacted Shaft blade stops  15  stopping the rotation of the Blades  7 . The Fin unit  9  halves and Blade sheaths  11  separate from Pivoting blades  7  as the Broadhead-Bullet  19  enters the Target material  37 . The fully deployed position of the Pivoting blades  7  will allow the maximum cutting effect the Pivoting blades  7  can achieve thus causing the most cutting effect to the target material as the Broadhead-Bullet assembly  19  travels through the Target material  37 . 
     The mass of the Core weight  13  will provide the Broadhead-Bullet  19  the majority of the kinetic energy it requires to complete its trajectory and pull it through the Target material  37 . The Pin support  31  will support the Pin  5  when the Broadhead-Bullet  19  strikes the Target material  37  thus keeping the Pivoting blades  7  from separating from the Shaft  1 .

     Operation of Invention 
     Preferred Embodiment FIGS.  17 - 31   
       FIGS. 17-31  detail the Broadhead-Bullet SS assembly  39  construction and operation. The Broadhead-Bullet Shot Shell here is intended to function within a 12 Gauge shotgun with a smooth bore barrel, as would a 12 Gauge shot or slug shell would. The Powder charge  25 , SS wad  55 , and the Broadhead-Bullet assembly  39  is all contained within the Shell  23  when the SS Broadhead-Bullet assembly  39  is in the pre-firing state. When the Broadhead-Bullet Shot Shell is fired from the firearm, the primer ignites the Powder charge  25  after the primer is struck by the firing pin. As the Powder  25  burns the expanding gasses produced pushes the SS wad  55  against the Broadhead-Bullet SS  39 , which is in turn pushed out of the Shell  23  and into Gun barrel  26 . The SS wad supports  65  maintain the circular profile of the SS wad  55  as well as maintaining the true position of the Broadhead-Bullet SS  39  along the horizontal axis of the Gun barrel  26  while the SS Wad  55  and Broadhead-Bullet SS  39  travels through the Gun barrel  26 . The SS wad  37 , when in the Gun barrel  26 , encases and protects the Broadhead-Bullet SS assembly  39  until it is ejected from the Gun barrel  26 , where the SS wad  55  is ejected from the Broadhead-Bullet SS  39 . The SS wad  55  allows the Broadhead-Bullet assembly  39  to travel through the Gun barrel  26  with a tight tolerance and little friction thus giving the Broadhead-Bullet SS  39  the accuracy the barrel can create while the Broadhead-Bullet is in flight towards the target. 
     When the SS pivoting blades  47  are in the stowed position the SS pivoting blade edge  57  is flush with SS shaft  41  and the two SS fin unit  49  parts are in contact with each other to form a continuous SS fin unit. In this state the Broadhead Bullet SS assembly  39  is either encased by the SS wad  55  or is in flight sans the SS wad  55 . 
     While in flight the SS fin unit  49  creates a pressure, via air flowing across the SS fin unit  49 , creating fluid resistance that is directed downward onto the SS pivoting blades  47 . This pressure is sufficient to maintain the stowed position of the SS pivoting blades  47  during flight until the Broadhead-Bullet SS  39  either strikes the Target material  37  or achieves a zero velocity state. SS fin unit support  63  maintains the desired shape of the SS fin unit  49  when the halves are combined and until the Broadhead-Bullet SS assembly  39  contacts the Target material  37  adding stability to the Broadhead-Bullet SS  39  during flight. The combined fluid pressure effect on the SS fin unit  49 , as well as the forward position of the SS core weight  51  would create a Center of Pressure rearward of the Center of Gravity therefore creating the conditions for a stable flying projectile. 
     The Broadhead-Bullet SS  39  would have a sub-sonic velocity of roughly 1000 ft/sec or 3 times the velocity compared to an arrow fired from a high-powered compound bow. This velocity would give the Broadhead Bullet SS assembly  39  an effective range of roughly 100 yards thus allowing for it to be used in areas limited to short ranges due to applicable hunting regulations. The trajectory of the Broadhead-Bullet SS  39  beyond 100 yards aggressively deteriorates. 
     A SS blade sheath  62  is attached to and encases the fore portion of the Pivoting blade tip  61 . As the Broadhead-Bullet SS assembly  39  strikes the Target material  37  the SS blade sheaths  62  and the SS penetrating tip  43  are the first portions of the Broadhead-Bullet SS  39  to contact the Target material  37 . As the SS penetrating tip  43  penetrates into the Target material  37  the SS blade sheaths  62  remain on the exterior of the Target material  37 . SS pivoting blades tips  61  slide along the inside portion of SS blades sheaths  63  forcing the SS pivoting blades  47  to rotate on SS pin  45  and outward from their stowed position and into the deploying position. The SS pivoting blades  47  ends deployment when the lower spine portion of Blades  47  contact SS blade stops  53  portion of SS shaft  41 . Here the SS pivoting blades  47  are oriented such that SS pivoting bladed edges  57  are facing forward towards the SS penetrating tip  43 . As the Broadhead-Bullet SS assembly  39  enters the Target material  37  the SS blade sheaths and SS fin units  49  are ejected from the Broadhead-Bullet SS assembly  39 . The SS pivoting blades  47  cut a wound channel through the Target material  37  until the Broadhead-Bullet SS assembly  39  depletes its kinetic energy. 
     The mass of the SS core weight  51  will provide the Broadhead-Bullet SS  39  the majority of the kinetic energy it requires to complete its trajectory and pull it through the Target material  37 . The SS pin support  59  is connected to and supported by SS core weight  51  and SS shaft  41 . SS pin support will support the SS pin  45  when the Broadhead-Bullet SS  39  strikes the Target material  37  thus keeping the SS pivoting blades  47  connected to the Broadhead-Bullet SS assembly  39 .
