Then there's the two levels of expansion dies from Redding...
Including a "Premium" one with a TiN plug (coated with Titanium Nitride)!
Cheers!
P.S. The "regular" Redding model has worked fantastically for me in 9mm: very much like the M-Dies from Lyman. Still going to give the new plugs from LEE a chance: at around $4 a pop how can one go wrong?
