The only way I can conceive of the OAL increasing after the crimp die is if the round is being significantly resized. My concern is if the soft lead is being compressed by the FC die, while the brass springs back. Are the bullets tight in the brass? 9mm should not need a roll crimp, just remove the case mouth expansion.
A lack of planning on your part does not necessarily constitute an emergency on my part.
