The .351 Winchester Self-Loading (also called .351SL) is an American rifle cartridge.

Winchester introduced the .351SL in the Winchester '07 self-loading rifle as a replacement for the Winchester '05 and the .35SL. The .351SL proved popular with police and security forces as the only chambering available in the Winchester Model 1907, and was used by France in both World Wars.[1] An experimental Thompson submachine gun was also made to fire .351SL in 1919, but was never produced commercially.[2]

The .351SL is inadequate as a deer round,[3] but is generally suitable for mountain lion, coyote, or similar medium-sized game, while being over-powerful and insufficiently accurate for varmints. It has had some popularity in the jungle, where its lack of long-range power or accuracy are less important.
