About the Henry Big Boy

The Big Boy chambers pistol cartridges in a brass-framed lever gun sized for hunting and range work. Available in .357 Magnum, .44 Magnum, and .45 Colt, the rifle digests the same loads a defensive revolver fires, so one ammunition type serves both guns. The twenty-inch barrel manages magnum pistol velocities well out to the distances where these cartridges remain effective, and the tubular magazine carries seven rounds in the common chamberings. Near seven pounds of weight keeps the gun steady offhand, and the brass receiver and octagon barrel give it the classic appearance buyers expect.
