Robert Stack, at 16 years of age, was one of the nation's leading skeet shooting champions. He came from a wealthy family, who could afford fine shotguns and cases of ammunition during the Depression.
His autobiography, "Straight Shooting" is well worth reading.
Stack, best known for playing federal agent Eliot Ness and for being a pilot in the comedy, "Airplane," was very good friends with Clark Gable.
In "Straight Shooting," Stack wrote that Gable had a clause in his acting contract that he would not work during duck season -- such a nut for duck hunting was he.
David Niven was a British officer (12 years or so) before he became an actor. He enjoyed shooting skeet with Gable, and the two often fished together. Gable was quite the outdoorsman, Niven said.
