I recently bought a used Dillon XL650. I bough new Dillon 9mm carbide dies 9mm conversion kit and some replacement parts for the XL650 to bring it back to new condition. Saturday night I tried reloading on it for the first time (my first time on a progressive). Everything went pretty well though I noticed some differences with the Dillion dies vs the Lee dies I have previously used for reloading 9mm.
The rounds I was loading were for shooting IDPA the following day. After running a batch of ammo for IDPA I do a quality check which included testing each round in a Dillon Case gauge. After gauging the ammo I loaded I found about 20% were rejected due to not fully seating or freely releasing from the case gauge. This I believe is due to the cases not being fully sized in the Dillon sizing and de-capping die. I had hear that the Dillon dies had some additional tapper that helped in aligning the case to the die on a progressive press, which is the reason I bought the Dillon dies.
I had noticed when I was setting up my die that there was a little more bulge at the bottom of the case with the Dillon dies than my Lee dies. I believe I have the sizing die adjust down as far as I can. When the shell plate is at the end of the top stroke the sizing die just hits it. I also don't believe I was short stroking the press.
On the left is one of the new rounds from my Dillon with Dillon dies. On the right is an old test round from my Lee Classic Turret with Lee dies.
Does anyone have any suggestions on how to prevent the bulge at the bottom? Should I not be using for Dillon dies if I don't want bulge at the bottom?
