Abstract
Disclosed are processes for loading a cartridge such as a shot shell with a shot load and a charge of buffer material. The processes employ a tube that is coaxially aligned with the axis of the cartridge case or shot cup, the tube having an outer diameter that closely fits into the inner diameter of the cartridge case or shot cup. Shot and buffer material are loaded, the leading edge of the tube is inserted to a sufficient depth to cause at least a portion of the shot load and buffer material to rise into the inner volume of the tube, and the tube removed. The insertion-removal cycle effects the efficient mixing of the shot and the buffer material and can be repeated as many times as desired.
Claims24
A process for loading a buffered shot shell cartridge, the process comprising:
- a) providing or obtaining a cartridge case having a fore end and an aft end, the cartridge case having an inner diameter and comprising a cartridge head and a primer at the aft end;
- b) sequentially loading into the cartridge case [i] a propellant adjacent the primer, [ii] an obturating component, [iii] a shot cup having an inner diameter, and [iv] in any order, a shot load and a buffer charge;
- c) coaxially aligning a tube with the axis of the cartridge case, wherein the tube has a length, a circular leading edge, an outer diameter, an inner wall, a wall thickness, and an inner volume, and wherein the outer diameter of the tube closely fits into the inner diameter of the shot cup;
- and
- d) one or more times, sequentially [i] inserting the leading edge of the tube into the shot cup to a sufficient depth to cause at least a portion of the shot load and buffer charge to rise into the inner volume of the tube, and [ii] removing the tube from the shot cup.
