The .416 Remington Magnum is a .416 caliber (10.36 mm) of a belted bottle-necked design. The cartridge was intended as a dangerous game hunting cartridge and released to the public in 1989. The cartridge uses the case of the 8 mm Remington Magnum as a parent cartridge. When the cartridge was released in 1988, author Frank C. Barnes considered the .416 Remington Magnum to be the "most outstanding factory cartridge introduced in decades". The cartridge was conceived as a less costly alternative to the .416 Rigby cartridge and was intended to replace the latter. While today the .416 Remington Magnum is considered in the field the most popular of the .416 cartridges, the .416 Remington did not replace the .416 Rigby as had been anticipated. Rather, it sparked a renewed interest in the .416 caliber (10.36 mm) cartridges which led to the revival of the .416 Rigby and the introduction of other .416 cartridges such as the .416 Weatherby Magnum and the .416 Ruger. The .416 Remington Magum is one of the more popular dangerous game cartridges used for the hunting of dangerous game in Africa. It also has been increasingly used in North America, in Alaska in particular for the hunting of and as a defense against large bears.〔 ==History and origins== As former European colonies in Africa gained independence, safari hunting on the continent began a slow decline due to resource mismanagement and political factors. This, in turn, led to a decline in interest in big bore rifles and cartridges used to hunt dangerous African game species. However, by the 1980s African nations recognizing the potential benefits, began developing areas as hunting and safari destinations. As interest in safari hunting in Africa increased so did interest in dangerous game rifles. Early on .416 Rigby had been one of the most celebrated medium bore magazine rifle cartridges during the heyday of African hunting. Today, loaded with modern smokeless powders, the .416 Rigby is considered a big bore cartridge. The Rigby was a large, voluminous cartridge in comparison to most magazine rifle cartridges of its time which had used cordite as a propellant and operated at a medium pressure. Rifles chambered for the cartridge required not only a longer action but also an over-sized bolt face, all of which increased the cost of the rifle chambered for the cartridge. Cartridges such as the .416 Rigby – which was considered an entry level cartridge in countries which mandated 40 caliber (10 mm) cartridges – lost out to cartridges such as the .458 Winchester Magnum and the .375 H&H Magnum which could be chambered in much less costly bolt action rifles. As ammunition for the cartridge dried out, professional hunters such as Selby put away their .416 Rigby rifles for the lack of available ammunition. The renewed interest in Safari Hunting in North America beginning in the 1980s created a market for a specialized African cartridge. African nations mandated minimum caliber legislation beginning in the 1950s which mandated minimum calibers for dangerous game hunting. The minimum cartridges for hunting of dangerous game was set at either the .375 H&H Magnum or at the 40 caliber (10.36 mm) with a few countries allowing the 9.3 x 62 Mauser as an exception to the rule. Remington realizing the opportunity designed what was to become the second dangerous game cartridge to originate in the United States to be commercialized – the first being the .458 Winchester Magnum. The introduction of the .416 Remington Magnum by Remington led to renewal of interest in the .416 caliber (10.36 mm). This in turn resulted in resurrection of the .416 Rigby cartridge when Ruger released the Ruger Model 77 RSM rifle chambered for the cartridge while Hornady began manufacturing .416 Rigby ammunition. Weatherby was to followed Remington's lead soon after, releasing the .416 Weatherby Magnum which was based on its .378 Weatherby Magnum cartridge. The design of the .416 Remington Magnum can be traced to wildcat cartridges like the .416 Hoffman cartridge of the 1970s and the .416 Barnes Supreme of the 1950s. George L. Hoffman of Sonora Texas solution to having a chamber in a common rifle action was to neck up an improved .375 H&H Magnum case to . The new cartridge named the .416 Hoffman was introduced in the late 1970s. The .416 Hoffman was mainly chambered in custom rifles. Remington realizing that a new market had opened, designed the .416 Remington Magnum cartridge to compete with the .458 Winchester Magnum, .375 H&H Magnum and the .416 Rigby. The Remington cartridge had a striking resemblance to the .416 Hoffman. The new cartridge, unlike the Rigby, could easily be chambered in pre-existing rifle models such as the Remington Model 700, Winchester’s Model 70 and any rifle which could fire a belted magnum cartridge based on the .375 H&H Magnum. This avoided the need for a costly new action or redesign of pre-existing rifle models all of which would add to the cost of the rifle. The .416 Remington like the .416 Hoffman uses an improved .375 H&H Magnum case as the starting point. The .416 Remington Magnum was based on the company’s then fairly new 8 mm Remington Magnum which was necked up to accept a bullet. The 8 mm Remington Magnum in turn was based on the .375 H&H Magnum which improved by blowing out to reducing the taper and increasing case capacity and then necking it down to accept a bullet. The resulting .416 Remington Magnum emulated the performance of the .416 Rigby and the .416 Hoffman in that like the Rigby and the Hoffman it was capable of launching a bullet at . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「.416 Remington Magnum」の詳細全文を読む スポンサード リンク
