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 Model 1905 self-loading rifle, a centerfire version of the Winchester Model 1903. 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. [1] Both the .32SL and .35SL were soon superseded by the introduction of the more powerful .351SL in the Winchester Model 1907. [2]
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. [3] 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.
