The .250-3000 Savage is a rifle cartridge created by Charles Newton in 1915 and is also known as the .250 Savage. The name comes from its original manufacturer, Savage Arms and the fact that the original load achieved a 3000 ft/s (910 m/s) velocity with an 87 grain (5.6 g) bullet.〔"(The .250-3000 Savage )" by Chuck Hawks〕 ==Background== Charles Newton designed the 250-3000 Savage case to fit the popular Savage Model 99 lever-action rifle. Newton recommended loading 100 grain (6.5 g) bullets at 2800 ft/s (850 m/s); but Savage Arms reduced bullet weight to obtain velocity of 3000 ft/s. The .250 Savage was the first American cartridge capable of achieving 3000 ft/s (910 m/s) velocity. Achieving that velocity may have been the reason for the choice of the light-for-caliber 87 grain (5.6 g) bullet. Newton questioned if the publicity advantages of velocity compensated for reduced penetration of the lighter bullet in larger game animals.〔Towsley, Bruce M. ''American Rifleman'' (July 2011) pp.54-57〕 The cartridge has a pressure limit of 45,000 CUP set by SAAMI. It lacks the power of the bigger .25-06 Remington but provides less noise and less recoil. Performance is very close to the .257 Roberts. Arguably it is a better overall cartridge for hunting than the more popular .30-30, but in recent years has lost ground to the .257 Roberts and flatter-shooting 6mm cartridges such as the .243 Winchester.〔 Currently there are very few new firearms being made in .250 Savage. It is an excellent cartridge with moderate recoil for hunting small game on up to deer-sized game.〔 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「.250-3000 Savage」の詳細全文を読む スポンサード リンク
