Can I use a 10mm reloading die (specifically Lee 3-die carbide set) to reload my .40 s&w? I know the case dimensions are the same (other than length of course), but is there enough adjustment in the die to interchange?

Midway has two sets, one set says .40/10mm the other only says 10 mm.

So make sure you get the right one and you are good to go.
