摘要

The hunting gun cartridge is loaded with lead shot, which it sprays in a square pattern onto the target. It has a wad with a skirt, and the space for the shot, when seen from above, is square. The space can be divided at different places in the lengthwise direction, particularly at the corners, and the sides of the square can be slightly concave. The base of the space can be flat, or of any convex or concave shape, and can have a central boss.
