The .32 Winchester Self-Loading (also called .32SL, .32SLR, or .32WSL) is an American rifle cartridge. Winchester introduced the .32SL and .35SL cartridges in the Winchester '05 self-loading rifle, a centerfire version of the Winchester '03. The .32SL never gained popularity as a hunting cartridge, although it may be suitable for the largest small game such as fox and coyote at ranges under 150 yards.〔Whelen, Townsend (1918) ''The American Rifle'' Century Co. p. 257.〕 Both the .32SL and .35SL were soon superseded by the introduction of the more powerful .351SL in the Winchester '07.〔 Stebbins, Henry (1958) ''Rifles: A Modern Encyclopedia'' Stackpole Books, p. 127 〕 When first introduced however, the notable firearm expert Townsend Whelen noted the .32SL cartridge as displaying similar ballistics as the .32-40 Winchester black powder, low-pressure cartridge.〔Whelen, Townsend (1918) ''The American Rifle'' Century Co. p. 257〕 He further suggests the best use of the .32 SL as being for rapid-fire target shooting for ranges up to 300 yards. Within such ranges, it is quite an accurate cartridge. In October 1940. an Army Ordnance circular suggested development of a light rifle using a .30 caliber cartridge similar to the "Winchester Self-loading Cartridge, Caliber .32" to replace the pistol and submachine gun. This led to the production of the "Caliber .30 SL, M1" cartridge directly based on the .32 SL in February 1941 and, after a design competition, adoption of the Winchester-designed M1 carbine in October 1941.〔Larry Ruth, ''M1 Carbine: Design Development and Production'', The Gun Room Press, 1979.〕 ==See also== *List of cartridges by caliber *List of rifle cartridges *Table of handgun and rifle cartridges *Winchester Model 1905 *Winchester Model 1907 *.35 Winchester Self-Loading *8 mm 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 Winchester Self-Loading」の詳細全文を読む スポンサード リンク
