Abstract: A golf club head has a perimeter formed by bending a tube into a desired perimeter shape, and securing a member over at least part of the loop to at least cover the loop opening and form the striking face. At least one plug of weighting material fills a portion of the tube at a predetermined location on the loop to form a weighted portion. Successive plugs of the weighting material and a lighter weight material may completely fill the tubular loop. Each plug is inserted while the material is in a flowable condition and the loop is held in a suitable orientation based on the location of the plug. The material is allowed to harden before adding the next plug.
