The .348 Winchester is an American rifle cartridge. It was introduced in 1936, and developed for the Winchester Model 71 lever rifle. The .348 was one of the most powerful rimmed rounds ever used in a lever rifle.〔Barnes, Frank C., ed. by John T. Amber. ''Cartridges of the World''. Northfield, IL: DBI Books, 1972. p52〕 ==Performance== It is excellent for any North American big game in woods or brush, if the 250 grain bullet is used, but not especially suited to long range, as a result of the need to use flat-nose slugs due to the Model 71's tubular magazine.〔 (Factory-loaded, midrange trajectory at is for the bullet, for the round, and for the slug.)〔 The loadings are preferred for anything past .〔 In 1962, Winchester dropped the factory 150 gr and 250 gr loads, retaining only the 200 gr. No other rifle ever was ever offered in .348 by Winchester (although Uberti has made some 400 rifles chambered for the .348 in the Cimarron 1885 Hi-Wall in 2005-06), and it has been supplanted by the .358 Winchester (in the Model 88).〔 (The Model 71 was discontinued in 1958.)〔 In 1987 Browning produced a modern version of the Model 71 in Japan. These have different thread sizes in places, most notably the barrels, and many parts will not interchange with the originals. The Browning version was a limited production model only. The case of the .348 is used to produce the 8-348w wildcat, used to rechamber World War 1-era rifles such as Lebel or Berthier, instead of the original 8x50mmR, still considered war materiel in France and therefore strictly regulated. The .348 is also the basis for the .348 Ackley Improved and .50 Alaskan. 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「.348 Winchester」の詳細全文を読む スポンサード リンク
