Projectile with expanding members

An expandable attachment for a lethal projectile comprising:

• a plurality of deformable open-biased members having a plurality of member ends including a joining end and a second end wherein each of the deformable open-biased members is resilient and capable of bending from a first memory position to a second memory position;
• wherein the joining end of the deformable members are attached to a mutual connection means, the connection means is mountable on the rear of the projectile such that upon firing of the projectile, the resilience of the deformable members causes the deformable members to respectively bend from the first memory position to the second memory position to radially expand with respect to each other springing forward the second member ends with respect to the direction of travel of the projectile, wherein when the projectile is disposed in a barrel of a firing means, with the barrel having an inner barrel wall, each deformable open-biased member includes a contact region engaging the inner wall of the barrel, the contact region of each member is positioned between the respective joining end and the respective second end, and each second end is positioned away from the barrel wall, and
• wherein, when the projectile penetrates object, said second member ends of the deformable members, with the deformable members disposed in the second memory position, engage the object to create more widespread destruction of the object, said members effectively slowing the projectile once inside the object effectively limiting penetration distance.

A firearm cartridge with an expandable attachment comprising:

• a casing comprising a base with primer, and a side wall forming a powder chamber with a chamber area;
• a projectile with an expandable attachment comprising
• a plurality of deformable open-biased members having a plurality of member ends including a joining end and a second end, wherein each of the deformable open-biased members is resilient and capable of bending from a first memory position to a second memory position;
• wherein the respective joining end of the deformable members are attached to the rear of the projectile, the members naturally disposed by the resilience of the members to extend outward from the first memory position to the second memory position, the members compressed toward each other when in the first memory position, trailing a body of the projectile so that the members in the first memory position may be located inside the chamber area, wherein when the cartridge is disposed in a barrel of a firearm, with the barrel having an inner barrel wall, each deformable open-biased member includes a contact region engaging the inner wall of the barrel, the contact region of each member is positioned between the respective joining end and the respective second end, and each second end is positioned away from the barrel wall,
• the chamber area filled with powder surrounding the deformable members;
• wherein upon firing of the projectile, the primer igniting the powder, the expanding gases therefrom causing the projectile to travel along the barrel of the firearm, the deformable members contact the barrel walls as the projectile travels the length of the barrel, upon exiting the barrel the deformable members outwardly expand to respectively bend from the first memory position to the second memory position to achieve an unrestrained condition with respect to each other, springing forward the second member ends with respect to the direction of travel of the projectile,
• wherein when the projectile penetrates an object, said second member ends engage the object to create more widespread destruction of the object, said second member ends effectively slowing the projectile once inside the object thereby limiting penetration distance.
