The .32 H&R Magnum is a rimmed cartridge designed for use in revolvers. It was developed in 1984 as a joint venture between Harrington & Richardson and Federal Cartridge.〔(.32 H&R Magnum at the Reload Bench )〕 The .32 H&R Magnum is produced by lengthening the .32 S&W Long case by .155", to 1.075". ==Performance== The .32 H&R magnum offers substantially more performance than other .32 caliber handgun cartridges, such as the .32 ACP, and can be considered an effective small game hunting cartridge. Its higher velocity〔(Ballistics By The Inch .32H&R results. )〕 offers a flat trajectory, while the light weight of the bullets results in low recoil. The older .32-20 Winchester was extremely popular in the Winchester lever- and Colt single-actions, available at the turn of the century, for small-medium game hunting. The .32 H&R offers near duplicate performance. One of the .32 H&R magnum's favorable attributes is that it offers .38 Special energy levels and allows a small-frame revolver to hold 6 cartridges, whereas a similarly sized revolver in .38 special would only hold 5 rounds. Penetration is also increased compared to the .38 special with bullets of the same weight. Max pressure for the .32 H&R Mag is set at 21,000 CUP by SAAMI.〔(.32 H&R Magnum data from Accurate Powder )〕 The .327 Federal Magnum is based on the .32 H&R Magnum and improves performance to levels near that of the .357 Magnum. 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 H&R Magnum」の詳細全文を読む スポンサード リンク
