Lyman .41 mag "M" expander??

[kevmc]

Where can I get a Lyman neck expander M die for .41 mag?
I've got one for 357 & 44, don't see .41 listed on Lyman's website.
Cast boolits sized to .411....

You appear to be out of luck.

I can't find one either.

There are several people here who will make you a custom expander insert.

Maybe you will get a strike.
