The shot cup base is a second tubular member and also has an open end and a closed end. A plurality of substantially parallel, outwardly protruding, second ribs circumscribe an outside of the shot cup base. The volume of a shot receiving portion is controlled by inserting the shot cup base a desired distance into the shot sleeve such that the two sets of ribs interengage. Apertures formed through the shot cup base cause the sidewall portions of the shot cup base to segment and open outward on expulsion from the muzzle of a shotgun increasing aerodynamic resistance. The increased aerodynamic resistance causes the shot cup base to separate from the shot string minimizing interference of the shot flight pattern by the shot cup base.
