  • 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.
