Maybe an answer?

Looking at the offerings, it seems as if the M-Dies are length sensitive. Perhaps the .32-20 is just too long to be supported by the shorter die? And, while they do not list it, perhaps the .327 would also use the die for the .32-20?

Sorry for 'question before thought'...it's been that kind of a day.
