I have been reloading for about a year. I 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!
When looking for clues 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. Interestingly I recall I had to adjust seating depth between these same case types to ensure consistent COAL.
I checked some ammo that I had loaded a while back on my Lee 4 hole Classic Turret press and those same headstamps seem to be ok. These were all cycled through the Lee FCD.
Anyone else have this experience?
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?
At this point I just pitched the offending headstamps into my brass recycle bin.
Your thoughts, experiences and advice are appreciated.
