Abstract:
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 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, andwherein, when the projectile penetrates an 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 member ends effectively slowing the projectile once inside the object thereby limiting penetration distance.
