The .401 Winchester Self-Loading (.401SL / .401WSL) or 10.33x38mmSR is an American rifle Cartridge (firearms), cartridge.
Winchester Repeating Arms Company, Winchester introduced the .401SL in the Winchester Model 1910, Winchester '10 self-loading rifle as a supplement to the Winchester Model 1907, Winchester '07 and the .351 Winchester Self-Loading, .351SL in their offering of hi-power, self-loading rifles. The only chambering available in the Winchester Model 1910, the .401SL was used by France, Russia, and American company security forces in the First World War.Houze, Herbert G. (2003). ''Winchester's First Self-Loading Rifles.'' 'American Rifleman' Vol 151(5) p.84.
The .401SL proved powerful enough for both deer hunting, deer and other large game at ranges under 150 yards.Whelen, Townsend. ''The American Rifle''. Century Co., 1918. p.274 Both 200gr and 250gr bullet weights were offered by Winchester and other ammunition manufacturers as factory loadings. With extra available detachable magazines holding 4-rounds each, the Model 1910 could provide substantial firepower for the big-game hunter. This feature helped promote the use of the .401SL on dangerous game such as moose and grizzly bear in spite of the lack of controlled expansion bullet designs, which doubtlessly would have improved game-taking performance and the subsequent reputation of the .401SL cartridge.Stebbins, Henry M. ''Rifles, A Modern Encyclopedia.'' Stackpole Co., 1958. p.274
The .401 SL is of similar size to the later .41 Remington Magnum; but the longer self-loading rifle cartridge produced a muzzle energy of with a bullet, while the magnum revolver is credited with a muzzle energy of with a bullet. The .41 Remington Magnum revolver comparison is not entirely fitting, however, as a cartridge will often produce twice the muzzle energy when fired from a carbine as it does from a typically much shorter revolver barrel.
