Thanks Shadow. I figured you must have been out of town or something.
I figured out that the RCBS 9mm die itself is big enough to allow the 10mm case to go in all the way, and the 9mm expander works perfectly. Also, I think since the Dillon sizing die undersizes the neck, that little flare may be there to help accept the expander. All my cases look great now.
I also had to adjust the sizing die to set the shoulder correctly, it wasn't as easy as just screwing down the die until it touched the shellholder.
I think I'll go back to the Dillon seating die as well. I just figured I'd try the RCBS seater to see if it helped. I also learned that a little One-Shot case lube helps a lot with the sizing.
I may break down and buy a chrony. I just don't want to spend a bunch of money on options I don't really need. Will the Shooting Chrony F1 Master suit me for the occasional pistol load development?
