As it happens, I know whose reamer you are using and can tell you what he uses. A .338 Ultra Redding Type S bushing die, and a .375 Ultra full length die for a body die.
I use a custom Redding .338-300 Ultra Mag full length die set that I sent back to open up a couple thousands extra on the shoulder, and a off the shell Redding .338 Ultra neck die that I just don't screw in all the way.
