Case activation bullet feeder
View Patent ↗A bullet feeding device having an expandable collet insertable into a die body. The die body is capable of receiving bullets from a source and directing 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 contracts above the tip of the bullet and prevents the passage of additional bullets until a new cartridge case is inserted. The expandable collet is capable of accepting bullets of different lengths and shapes. In addition, the expandable collet is easily interchangeable with expandable collets of other sizes to be compatible with bullets of different diameters.
1. A method of feeding a plurality of stacked bullets into an upwardly extending bullet receiving end of a die body to be placed in cartridge cases inserted into an opposite downwardly extending receiving end of the die body, the method comprising the steps of:
retaining the plurality of stacked bullets in the receiving end of the die body by supporting the bottommost bullet in the plurality of stacked bullets by a plurality of bullet support surfaces of a plurality of circularly arranged finger portions of a collet, each finger portion resiliently and integrally connected to a collar portion of the collet;
inserting a cartridge case upwardly into the collet to engage interior surfaces of the finger portions below the bullet support surfaces of the finger portions with an upper lip of the cartridge case thereby deflecting the finger portions with the bullet support surfaces outwardly allowing the bottommost bullet in the plurality of stacked bullets to be dropped into the cartridge case.
2. The method of claim 1 , further comprising the step of withdrawing the cartridge case downwardly within the collet to disengage the lip of the cartridge case from the interior surfaces of the finger portions whereby the finger portions retract to block the next bullet stacked above the bullet placed in the cartridge case.
3. The method of claim 2 further comprising the step of repeating the process through the stack of bullets.
4. The method of claim 3 comprising the steps of providing a plurality of bullets of a different size and changing out the collet from the die body with a different collet compatible with the different size of the plurality of bullets.
