ABSTRACT:
A shotshell wad for use in a shotgun shell is provided. Three discs are disposed within a generally cylindrical tubular wail, and define a gas seal section, a middle section, a shot cup extension section, and a shot cup section. The third disc, which separates the shot cup extension section and the shot cup section, is detachably connected to the tubular wall such that when the shotshell is fired, the third disc breaks away and travels rearward relative to the rest of the shotshell wad to a position adjacent to the second disc. A plurality of fingers are defined by a plurality of lateral cuts through the tubular wall in the shot cup section extending from a point in the shot cup section to the forward end of the tubular wall. The tubular wall also includes a plurality of circumferential cuts passing therethrough substantially at the point where the plurality of lateral cuts terminate. The plurality of circumferential cuts extending through a section of each of the plurality of fingers. A plurality of lateral ridges extend inwardly from the tubular wall from substantially the point where the plurality of lateral cuts terminate to substantially the forward end of the tubular wall and are positioned at substantially the center of each of the plurality of fingers.
