ABSTRACT:
Shotgun shell testing apparatus positions a loaded shotgun shell in the path of a light source. An observer, generally a shooter, places his or her supposedly properly loaded shotgun shell in a receiving space of this apparatus and turns on the lighting energy source. By observing the resulting internal derived image of the fiber derivative portions of the shell casing, often observable at the exterior of the apparatus, and comparing this image observed with the likeness of an earlier image reflecting a properly loaded shotgun shell of the specified power charge, a shooter is able to determine if the shotgun shell being tested, via this observation, has been correctly loaded in respect to the positioning of the powder, wad, and shot.
