ABSTRACT:
An integral, solid bowling ball, devoid of any significant hollow portion, with inherent hooking characteristics has an elongated rod-like core that is symmetrical about the finger hole axis of the ball. The core is much denser than the encompassing body of the ball, preferably by a factor exceeding 2:1, has an axial length exceeding six-tenths of the ball diameter, and has an average diameter of about one-third of the ball diameter, with the core providing about one-fourth of the total ball weight. A frusto-conical core shape is preferred.
