It was a modification of the Springfield rifled musket Model 1861. It was later replaced with the Model 1866. ==Description== During the U.S. Civil War, the advantage of breech-loading rifles became obvious. The rifled muskets used during the war had a rate of fire of 2 or 3 rounds per minute. Breech-loading rifles increased the rate of fire to 8 to 10 rounds per minute with the additional advantage that they can be easily loaded from a prone, rather than standing, position, reducing the rifleman's visible cross section and thus vulnerability to counter-fire. As the Civil War drew to a close, the U.S. Ordnance Department requested prototypes of breech-loading weapons from arms manufacturers all over the world. After considerable testing, the prototype developed by Erskine S. Allin of the government-operated Springfield Armory was chosen for its simplicity and the fact that it could be produced by the modification of existing Springfield Model 1863 muskets. These modifications cost about $5 per rifle, which was a significant savings at a time when new rifles cost about $20 each. Patent No. 49,959 was issued to Erskine S. Allin on September 19, 1865, describing the design. 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「Springfield Model 1865」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
