  • Patent number: 4516460
    Abstract: The present invention relates to a method and apparatus for cutting a series of uniformly spaced longitudinal slits in a cylindrical shotgun shell wad. The wad slitting apparatus, with which the method can be performed, is a cylindrical member having upper and lower portions. A plurality of cutting members are uniformly spaced about the lower portion and project radially outwardly therefrom, with each cutting member having a downwardly facing cutting edge spaced a predetermined distance from a bottom edge of the cylindrical member. In use, the upper portion of the cylindrical member is secured to a movable ram member, which may be the ram tube of a shotgun reloader, and the lower portion is inserted into a wad positioned on a fixed plate. The ram member is then moved toward the plate, causing the cutting members to make a plurality of longitudinal slits in the wad with the slits extending from the upper end of the wad to an area spaced from a lower base portion of the wad by said predetermined distance.
