The Winchester Company introduced the 351 WSL in 1907 for the Model 1907 SL rifle,
Please note, again: SL = Self-Loading or Semi-Auto.
The 351WSL was more powerful then the 35 WSL, but still not suitible for deer-sized game, and the
rifle was discontinued in 1920; however, as with the other WSL cartridges, the 351 was produced until
app. mid-1950s.
