Thanks so much for all the comments and advice. I managed to get a hundred brass ready for powder and bullets which should be in tomorrow.
I did vary a bit from the instructions on the sizing die so that I slightly cam over.
I am assuming that since I will be loading jacketed bullets that the post-sizing function of the FCD would not be appropriate.
Again, thanks for all the info. I do try to research as much as possible before asking questions here, but the Q&A I get here really clears issues up for me.
