 In 1912, John Rigby & Co. lost the exclusive British sales contract to a member of the Mauser family, but Rigby continued to base its magazine rifles on Mauser (and Mauser-style) actions and still does so today.Among professional and sporting hunters in India and Africa, Rigby became known as the 'aristocrat of bolt-action rifles'.In addition to its .275, Rigby developed an equally successful medium-heavy game round known as the .350 Rigby, and its rimmed counterpart for double rifles, the .350 No.
