Abstract
The present invention is an inertial bullet puller comprising a rigid tough transparent plastics material carrier tube having an opening at its upper end adapted to receive a cartridge and a head portion at its lower end adapted to be struck against a hard surface. The carrier tube is affixed to the end of a handle in a manner similar to the construction of a hammer. However, the carrier tube is not completely perpendicular to the handle, but instead, resides at an angle to the handle. At the upper end of the carrier tube is disposed an annular segmented cartridge support. A cap at the upper end of the carrier tube having a tapered inner end provides a cam surface for positively moving the annular segmented cartridge support radially inwardly and holding it in position. When a cartridge is inserted through the annular segmented cartridge support into the opening at the upper end of the tube, the cartridge support expands to pass the larger diameter portions of the cartridge, and then as the cap is tightened, the cartridge support contracts into the cannelure. In use the lower end of the tube is struck once or twice against a hard surface until the bullet is observed to pull free of…
