9mm SDB load setback issues
Quote from Reloader on December 18, 2012, 10:34 pmI got a new (to me) Dillon SDB and just loaded a couple hundred rounds of 9mm with Berry's 124gr plated FP and 4.2 gr W 231. I am loading to 1.067" COAL.
The issue:
I was checking COAL and spot testing by pressing some into bench to ensure they are properly seated I discovered to my alarm that there were several that I was able to push the bullet back into the case against the bench!I noticed that the loads using cases with FC or Blazzer headstamp were the only ones that were loose. The WIN, RP and SB cases hold fine with no change to the die adjustments.
I do recall I had to adjust seating depth between these same case types to ensure consistent COAL.
Has anyone else reported this experience?
I am learning that these cases are thinner walled from reading elsewhere. My follow on questions are
Why would they seat correctly on my turret press and not on my SDB?
Is the seating die and crimp die that much different on the SDB than the Lee?
Or is my SDB just still not quite adjusted properly?
Your thoughts, experiences and advice are appreciated.

Now put a fired piece of brass into station one and pull the handle down. The bottom of the size die should still contact the top of the shellplate. If it does not, contact us for a replacement toolhead friction plate.
