The .401 Winchester Self Loading or .401WSL, was introduced in 1910 for the new model 10 autoloading rifle and both were discontinued in 1936. This .406" diameter bullet was tailor made to be the best performing bullet to reload for your .401 Winchester Self Loading rifle. This 240 grain version is the heaviest available with available load data that will restore the function of any .401 WSL!
Bullets are made by hand in the USA after orders are received and can take over 6 months to receive.
