The present invention is directed to improved multi-layer golf ball compositions and the resulting regulation balls produced using these compositions. In this regard, a lighter core is produced and metal particles, or other heavy weight filler materials, are included in the cover compositions. This results in a molded golf ball exhibiting enhanced interior perimeter weighting. Preferably, the particles are included in an inner cover layer (or mantle) of a solid, three-piece multi-layered golf ball. The weight of the core is reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. It has been found that the combination of the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin. This results in a golf ball exhibiting enhanced distance without substantially effecting the feel and durability characteristics of the ball.
