Golf club head or other ball striking device with weighted body member

An iron-type golf club head comprising:

• a face member comprising a hosel, a face having a substantially flat ball striking surface configured for striking a ball, and a portion of a sole formed of a metallic material, wherein the face member is formed primarily of a metallic material, and wherein the face has a loft angle of about 20° to about 65°;
• a body member connected to the face member and forming at least a portion of an iron-type body extending rearward from the face, wherein the body member is formed at least partially of a polymer material, and wherein the body member extends from a heel side of the face member to a toe side of the face member;
• wherein the face member and the body member form an open rear cavity;
• wherein the body member has a fiber reinforced portion comprising the polymer material and containing a fiber reinforcing material within the polymer material;
• and
• wherein the fiber reinforced portion is connected to the face member by forming the polymer material of the fiber reinforced portion in connection with the face member using a co-molding process.

A set of iron-type golf clubs comprising:

• six iron-type golf clubs, each having an iron-type golf club head comprising:
• a hosel, a face member having a substantially flat ball striking surface configured for striking a ball defined by a plurality of peripheral edges, wherein the face member has a peripheral wall extending rearwardly from the plurality of peripheral edges, wherein the face member is formed primarily of a metallic material, and wherein the face member has a loft angle of about 20° to about 65°;
• a body member connected to at least a portion of the peripheral wall, the body member forming at least a portion of an iron-type body extending rearward from the face, wherein the body member is formed at least partially of a polymer material, and wherein the body member extends from a heel side of the face member to a toe side of the face member;
• wherein the body member has a fiber reinforced portion containing a fiber reinforcing material dispersed within the polymer material;
• and
• wherein the face member and the body member form an open rear cavity.
