    摘要: A bullet designed to expand reliably at subsonic velocities has a front end region divided by notches into petals and a groove on its exterior surface. Each notch may be separated into a notch forward segment and a notch rear segment by a discontinuity. Each notch may be cut with a depth such as to provide a web of material extending along a portion of the length of a central cavity.

    摘要: Improvements in an expanding arrowhead where the initial launching thrust of launching an arrow keeps the blades retracted within the head of the arrow. The blades remain retracted because the center of mass of the blades is on the opposite side of the rotational pivoting axis of the blades. When the blades contact a target a wing tip on the blades pull the blades open. There are two or three blades that can be retained within the head of the arrow. The blades are loosely retained in a retracted orientation for transportation. The retention is sufficient to overcome the forces or gravity yet release with slight force on then ends of the blades. When the arrow is pulled through the wound track the blades fold back into the head or body.

    摘要: A projectile comprising a central slug axially circumscribed by a segmented cylindrical sleeve having a plurality of fragmenting segments and a base that opens into an interior cavity. A flange may circumscribe the base. A wad may fill the interior cavity, remaining attached to the central slug. The wad travels with projectile to set a geometric center behind the center of gravity of the projectile. A radially-segmented cylindrical sleeve receives the central slug. The cylindrical sleeve comprises inwardly sloping segments for funneling target material into the recess between the slug and cylindrical sleeve. The segments bend outwardly upon impact and are adapted to bend, compress or flex inwardly to pass through a muzzle choke.

    摘要: An auxiliary cutting implement for attachment between a broadhead and arrow shaft includes preferably two or more coils each having two cutting edges formed along their opposite elongated side edges. As the coils pass through the animal they unroll and slice through animal flesh in all directions. The coils are biased toward their rolled position which increases the multi-directional movement of the coil and cutting edges through the animal resulting in a large cutting area and fast kill as compared to the broadhead alone.
