Our Assessment: From Wikipedia: “The . 458 Winchester Magnum is a belted, straight-taper cased, dangerous game rifle cartridge. It was introduced commercially in 1956 by Winchester and designed to compete against the .450 Nitro Express and the .470 Nitro Express cartridges found in big bore British double rifles. The .458 Winchester Magnum remains to this day one of the most popular dangerous game cartridges. Many guides in Alaska and Canada carry rifles chambered in this cartridge to provide a defense against the largest bear species for themselves and their clients.”. This is an exceptionally nice looking and well-made rifle. It started out in 1949 as a Winchester Model 70 and was later re-barreled and customized by Griffen & Howe of New York. The pre-1964 Winchester rifles were known for their smooth functioning and quality of manufacture. The rifle has a left-side receiver scope mount base for a quick-detachable offset scope mount and an engraved quarter rib mounted to the barrel with an express sight dovetailed into the rib. The stock was checkered by Al Biesen. known for his fleur-di-leis checkering pattern. He was made famous by author Jack O’Connor who wrote about him in magazine articles. The first rifle he restocked for O’Connor was considered “too pretty” by O’Connor, but the second became O’Connor’s favorite rifle. There are either gold or brass initials inlet into the belly of the stock reading “RS duP”, and our consigner believes this rifle was once owned by a member of the DuPont family. This rifle is in about Fine overall condition. The bore is bright with sharp rifling and no erosion. This rifle was featured in Page 92 of Rick Hacker’s “50 Famous Firearms You’ve Got to Own”. This rifle is really beautiful, so please see our pictures!! This will be great for hunting the big bears up in Alaska or any of the African “big five”. You might find a safari rifle that is newer than this one, but we doubt you will find one better looking or better made.
