The .32-20 Winchester, also known as the .32 WCF (Winchester center fire), was the first small-game lever-action cartridge that Winchester produced.〔"(Levergun loads: the .25-20 Winchester )" by John Taffin, Guns Magazine, April 2004〕 It was initially introduced as a black-powder cartridge in 1882 for small-game, varmint hunting, and deer.〔"(.32-20 Winchester (HV-92) )" from Accurate Powder〕〔"(The .32-20 Winchester )" by Chuck Hawks〕 Colt produced a single-action revolver chambered for this cartridge a few years later.〔"(32-20 WINCHESTER CENTERFIRE 1882 )" by Paco Kelly at Leverguns.com〕 The name .32-20 refers to the bullet and standard black-powder charge of . ==Performance== Although the .32-20 cartridge was occasionally used for deer hunting in the past, many now consider it too light and low-powered for deer; it is much better suited to small game. It has a good reputation for accuracy in rifles as well as the few handguns that have been chambered for it.〔〔〔 Because of its low power, it destroys very little meat, making it a good hunting round for appropriately sized game, up to about .〔"(.32-20 Winchester )" at The Reload Bench〕 The cartridge is now approaching obsolescence, as shooters turn to other similar but more powerful and flexible loads. The power level of more modern .32s, such as the .32 H&R Magnum and the .327 Federal, equal or surpass the .32-20 in modern firearms. Although it is an inexpensive cartridge to reload,〔 care must be taken by the reloader because of the extremely thin walls of the cartridge case.〔People who do hand load the .32-20 feel this is not problematic, and if usual care is taken, there is no special problem with the case.〕 Energy and pressure levels for handloading are determined based on the strength and condition of the firearm action to be used. Because most firearms chambered for this cartridge are older (e.g. early model Winchester Model 73 and 92 rifles as well as older Colt and Smith & Wesson revolvers) factory ammunition usually has reduced pressures from what can be achieved through handloading. Most factory ammunition exhibits ballistics of about and of energy at the muzzle with a bullet from an 18 to 20 inch rifle barrel. The performance characteristics of the cartridge listed in the sidebar should be considered ''maximum'' performance parameters obtainable, and even then only with a modern weapon designed for higher pressure loads. Factory-type loads - and reloads mimicking factory type loads - are the safe maximum loads for use in older weapons chambered for this cartridge, as most of the weapons the cartridge is chambered. Few if any companies still manufacture hunting weapons in this caliber. 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「.32-20 Winchester」の詳細全文を読む スポンサード リンク
