  • Publication number: 20040025677
    Abstract: Reloading apparatus for reloading ammunition shell cases includes a shell case holder having a pair of yieldably biased gripping fingers positioned to engage and hold the rim at the base of the shell case. A resizing die mounted for sliding about a shell case has a lower rim adapted to engage and move the holding fingers away from engagement with the rim and thus provides substantially full length case resizing. Ejector mechanism in the resizing die is operable to urge the shell case out of the die and hold it in position to be regripped by the holding fingers as the die and support are moved away from each other.

  • Patent number: 5079986
    Abstract: A cylindrical die body has an axial bore in which there is an annular tapered shoulder. A cylindrical collet is adapted to fit coaxially in the bore of the cylindrical body. The collet has an axial bore extending over the majority of its length for accommodating the body of an ammunition case and has a smaller coaxial bore through which a bullet installed in the mouth of the case can extend. The fingers of the collet terminate in finger tips which surrounds the small bore. The mouth of the case which holds the bullet extends into the space between the collet finger tips such that when the collet is pressed into the cylindrical die body, tapered surfaces exterior of the collet run ionto the tapered shoulder in the die body to generate a wedging action which forces the tips of the collet fingers in a radial direction into the mouth end of the cartridge case to thereby crimp the mouth end of the case to the bullet.

  • Patent number: 4869148
    Abstract: A loading die for use within an ammunition loading press that is designed for maximum accuracy. Whereas prior art loading dies are inaccurate due to angular and axial misalignment of the various die, ram and ammunition components, the invention has clearance between the sliding sleeves and the die body. The sliding sleeve locates accurately over the cartridge case and due to the clearance, any axial or angular misalignment between the sliding sleeve and die body will not affect the seating accuracy.

  • Patent number: 4836078
    Abstract: An ammunition reloading die having a generally cylindrical axially bored body and an external thread for mounting it in a reloading press. In one embodiment, a case sizer element is threaded onto and is removable from the nominally lower end of the die body into which cases are pressed for sizing the outer diameter. A stepped mandrel is insertable in the die body. It has a decapping pin extending from its nominally lower end. A bullet seating plug is screwed into the upper end of a body's bore for backing up the mandrel when a case is being pressed onto the mandrel to expand and flare the mouth end of the case and to expel the spent primer from the case. A new primer is installed and the case is charged with powder and a bullet is set in the mouth after which the case is pressed into the die body while the mandrel is removed but the bullet seating plug is installed in the die body in which case pressing the case into the die body seats the bullet and crimps the case in the bullet.

  • Patent number: 4754684
    Abstract: A method and device (A) for cutting a shotgun shell (14) for shooting in a shotgun chambered for shorter shotgun shells includes a base (10) and shell receiving tube (12). A shell (14) is held in tube (12) above a knife (32) in such a manner that a circumferential slit is formed in shell casing (20) around the inside edge (24) of crimp (22). The knife is carried on a movable knife blade holder (40) which moves toward base (10) to engage the knife in the crimped edge as the shell is rotated. Upon shooting of shell (14), the crimp material separates from casing (20) leaving the shell of a shorter length. In this manner a two and one half inch (21/2") shell is obtained from a two and three-quarter inch (23/4") and three inch (3") shells which may be reloaded or disposed of.

  • Patent number: 4637291
    Abstract: A combination ammunition re-loading die having an elongated housing. The housing is externally threaded at both ends to enable entry of either end into the die holder of a reloading press. An expander post is integrally formed at one end of the housing. The other end is provided with a cartridge receiving end opening. A threaded opening in the post receives a threaded shaft projected through to the cartridge receiving end opening. The projected end of the shaft carries a re-loading member, e.g. a bullet seating plug or de-priming pin. The shaft is adjustable within the post opening to adjust the position of the member. The housing can be inserted in the die holder to first present the expander post to the cartridge, and then inverted to present the bullet seating plug or de-priming pin.

  • Patent number: 4566366
    Abstract: A hand held cartridge case reloader has a first elongated handle body on which there are spaced apart laterally extending members. The upper member is threaded to receive standard cartridge reloading tools. The lower member is bored to receive a reciprocable ram for holding a cartridge case at its upper end. A second handle body has a pivotal connection to the lower end of the ram and another pivotal connection to the lower end of a link whose upper end is pivotally connected to the lower end of the first handle body adjacent the ram.

  • Patent number: 4512235
    Abstract: An ammunition case reloading press is based on an O-frame die cast from a low strength metal. A case carrying ram is driven reciprocably through a bottom member of the O-frame toward and away from a die in a top member. A compound lever system is actuated by a manual operating arm to drive the ram. A stop prohibits the links of the lever system from toggling into dead center position to thereby limit the stress of the O-frame. The operating arm is designed so it will flex to signal the user that unnecessarily great resistance is being offered and that the die should be adjusted relative to the ram to reduce the stress. The operating arm and lever system pivots are askew to a vertical plane passing through the frame so the arm swings clear past the side of the O-frame and so there is a clearer line of sight to the opening in the O-frame where the cases are placed on and removed from the ram.
