Originated by the British firm Holland & Holland in 1912, this is one of the original belted, rimless, magnum-type cartridges. It has been used as the basis for numerous wildcats and most of the Weatherby cartridges. H&H furnished it in a magnum Mauser action, and Griffin & Howe chambered rifles for it beginning about 1926. The Western Cartridge Co. first offered it in 1925. At present, Federal, Remington and Winchester load the .375 H&H. The first commercial rifle of American make to chamber the round was the Model 70 Winchester in 1937. Weatherby rifles were at one time available in .375 H&H, as was the Remington Model 725 Kodiak.
