Bullet Setting Patents (Class 86/43)
  • Patent number: 8707845
    Abstract: A bullet feeding device has an expandable collet insertable into a die body. The die body receives bullets from a source and directs the bullets to the expandable collet. The expandable collet restricts the passage of the bullet through the die body until the mouth of a cartridge case is inserted into the die body opposite the bullet. The mouth of the cartridge case causes the expandable collet to expand and allow the single bullet to pass through the expandable collet and be placed in the mouth of the cartridge case. As the completed cartridge is drawn from the die body, the expandable collet and prevents the passage of additional bullets until a new cartridge case is inserted. The bullet feeding device may accept bullets of different lengths and shapes. The collet is interchangeable with expandable collets of other sizes to be compatible with bullets of different sizes.

  • Patent number: 6050169
    Abstract: A fired rifle cartridge is resized in the cartridge neck area for reuse. A first die set is employed to compress the cartridge neck such that the inner surface of the neck fits a standard size bullet. A second die set is used to expand selected areas of the cartridge neck to snugly fit the firing chamber. The resultant ammunition round can be fired with a greater degree of accuracy than ammunition resized by prior art procedures, because the longitudinal axis of the cartridge neck coincides with the bore axis of the firearm.

  • Patent number: 5179243
    Abstract: The present invention provides an automatic feed mechanism for the assembly of ammunition. Ammunition is assembled in the feed mechanism by the joining of bullets with their respective shell casings, one at a time. The automatic feed mechanism is utilized in conjunction with a progressive reloading press. The automatic feed mechanism comprises a replaceable feed tube having a precise bore. The bore is designed to accommodate the free fall of a single bullet of a given caliber for precise alignment with a shell casing of the same caliber. The precision of this alignment stems from the precise bore tolerance for a given bullet caliber, with the union of the bullet and the shell casing only under the influence only of gravitational forces. Should it be desired to join a bullet of another caliber with a shell casing of the same or different caliber, the feed tube is easily removed and replaced by one having the proper dimensions and internal bore to assemble the new ammunition.

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.

An outer guide member is slidably contained within the retainer housing that moves between a home position and a stop position. The guide member has a contoured lower chamber for receiving a shell casing therein the lower communicates with a smaller upper chamber adapted to receive a bullet therein. A second inner guide member is slidably contained in the bullet chamber and is also arranged to move independently within the outer guide member between a home position and a stop position. The inner guide member has a recess formed in its bottom wall for engaging the nose section of a bullet as it enters the bullet chamber. As the ram moves the bullet and the casing into the die, both become firmly seated in their respective chambers.

A probe is mounted on the lower end of the plunger which contacts the powder deposited in the cartridge shell, wherein the probe lifts the plunger so that the groove in the plunger may receive the ball upon the presence of a proper amount of powder so the sleeve can slide upward into the housing allowing the cartridge to enter the housing. Preferably, the powder level sensing device is adapted to be mounted onto existing reloading press frames, particularly the progressive reloading press frame. Also disclosed is a method for adjusting the powder level sensing device to accommodate various cartridge shells and desired powder levels.
