Patent ID: 8241157

Claim:
A projectile system, comprising: an arrowhead; an arrow shaft; that includes a projectile insert structure, the projectile insert structure comprising: a hollow portion that is coupled to an aluminum sleeve, wherein the aluminum sleeve is coupled to an interior portion of the hollow portion, wherein the aluminum sleeves reduces wear to the hollow portion; a weight constructed with a predetermined weight length, wherein the weight is movably secured within the hollow portion of the projectile insert system, wherein the weight has a mass from about 5 grains to about 1000 grains; a first padding insert rigidly secured at a first end of the hollow portion, wherein the first padding insert includes a first distal end adjacent to an arrowhead and a first proximal end opposite the first distal end, and wherein the first padding insert is constructed of nylon; a second padding insert rigidly secured at a second end of the hollow portion to absorb an impact of the weight after the weight traverses the hollow portion, wherein the second padding insert includes a second distal end adjacent to the arrowhead and a second proximal end opposite the second distal end, and wherein the second padding insert is constructed of nylon; a first magnet rigidly secured within the first distal end to protect the first magnet from the impact of the weight, the first magnet removably securing the weight; and a second magnet rigidly secured within the second proximal end to protect the second magnet from the impact of the weight, the second magnet removably securing the weight, wherein the first padding insert and the second padding insert are separated by a predetermined distance, the predetermined distance being equal to the predetermined weight length plus an additional length that ranges from about 1/8 inches to about 15 inches, wherein the hollow portion provides a pathway for the weight to travel toward the second end of the hollow portion when a force is exerted on the projectile insert structure that causes the weight to become unsecured from the first magnet.
