RCBS die question

[Melnibonean]

I just picked up a set of 10mm RBCS dies. "10mm" is stamped on the dies. These should be ok for me to use to reload both 10mm AND 40 S&W, right? I don't see how there could be a difference, except for the obvious (OAL)

Yes they can be used for 40 s&w

Without having tried them my first question would be: Will the seating die crimp .40 S&W?

How would I know?
