An all metal hollow golf driver is formed by casting a first main part from metal, e.g., stainless steel, in the shape of practically a complete golf driver, except for an opening in one side of the driver body, e.g, the sole side. A second cast part fits within the opening and is weldable thereto to form a complete integral hollow metal golf driver. The weight (mass) of the driver is distributed in order to reduce its torque and/or deflection.
