401 WSL Brass Cases
By A Mystery Man Writer
These 401 WSL (Winchester Self Loading) reloadable brass cases were first introduced by Winchester in 1910 for its then new Model 10 Autoloading rifle. Both the rifle and ammunition was obsolete by 1936 but ammunition was loaded until after World War II. This brass uses a RCBS #32 shell holder, item number RCB9232.
