As a kid I enjoyed Roy Chapman Andrews' accounts of his exploration of the Gobi desert region in the 1920s in search of dinosaurs. (He is mainly now known as the model for "Indiana Jones.") I remember he first used the MS 6.5x54mm carbine, and later settled on the Savage 99 cal. .250-3000 for hunting and defense against the natives, but don't recall what shotgun(s) he used in his expeditions.
I know he was a bird hunter from his youth in southern Wisconsin and was given a double by his father at an early age, but don't know what he used later. Anybody know or have a source?
