The 6.5×54mm Mannlicher–Schönauer also known as 6.5×54 Mannlicher–Schönauer Greek is a 6.5 mm (.264" cal.) rifle cartridge used in the Mannlicher–Schönauer rifle. 6.5 mm bullets are typically known for their high ballistic coefficients and sectional density, which gives them great stability in flight, resistance to wind deflection, and excellent penetration. ==Hunting use== Walter Dalrymple Maitland "Karamojo" Bell, who shot more than 1,500 elephants〔(【引用サイトリンク】title=W.D.M. Bell and His Elephants )〕 in the period 1895-1930, had a very high regard for the 6.5mm Mannlicher–Schoenauer, using it for approximately 300 of these kills.〔(【引用サイトリンク】title=W.D.M. Bell and His Elephants )〕 Daniel Fraser of Edinburgh, Scotland built him a special, lightweight rifle in that calibre. He only set it aside when he was unable to acquire dependable ammunition for it, and turned to a .275 Rigby Mauser magazine rifle instead. The .275 Rigby cartridge is interchangeable with the 7×57mm Mauser. Bell's legendary name has remained closely linked with the 7mm Mauser, but the 6.5 Mann.–Sch. was his first preference. The American cartridge, the .257 Roberts also demonstrates many of the virtues of the 6.5×54mm. The .257 Roberts was originally designed as a wildcat cartridge by Ned Roberts, and is based on the 7×57mm cartridge. Note that the 6.5×54mm shoots a .264" bullet.〔Ganyana, "The 6.5 X 54 Mannlicher-Schoenauer," ''African Hunter'' 5 (February, 1999)〕 The 6.5×54mm was referred to by the writer Ernest Hemingway as the .256 Mannlicher. Though it never replaced his favorite .30-06 Springfield, he did speak highly of it as a lion cartridge, and it was the favorite of his African guide and professional hunter Phillip Percival.〔Ernest Hemingway, ''Hemingway on Hunting'' (NY: The Lyons Press, 2001)〕 The Kenya game warden and naturalist A. Blaney Percival also favored the 6.5×54mm.〔A. Blaney Percival, A Game Ranger on Safari (London: Nisbet & Co., 1928)〕 In part, the 6.5×54mm's reputation stems from its use of a bullet, giving the projectile very high sectional density and therefore penetrating ability. It requires a fast rate-of-twist rifling (about 1 in 9") to stabilize such a long bullet. 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「6.5×54mm Mannlicher–Schönauer」の詳細全文を読む スポンサード リンク
