Hi

I have buy a brand new XL650 with original Dillon DIE for 9mm.

I follow the manual for the mounting and DIE adjustement. But on stage 1 (reseize and depriming) i think the Die work not normaly.

The reseizing of the case is like shrinking at the middle to the top of the case ( see attached picture).

for the adjustement, i put the shell holder UP and i screew the die up to is touching the holder. after i try to reseize.


What i do wrong, or it is possible the die is defect.??


Please Help me



 
That's normal with Dillon product, you end up with a coke bottle shape as they like to call it, you could have a shell fired from a block and it will take care of it.
I had that very same issue as well when I first got mine and call those guys up to verify, btw they are amazing people to deal with.
Happy loading, it's a great machine.
 
9mm cases are tapered, but most carbide dies use only a narrow carbide ring. The case mouth is the right diameter, the base is the right diameter, but there is a parallel section followed by a more sharply tapered section in between these two points. It looks different from a factory round, but works just fine.

A die that duplicates the continuous taper of a factory round would have to have a wider carbide insert to match the length of the case. This would be more expensive to make.
 
You are doing the right thing by stopping the process and asking questions. in this case, because it is Dillon and its support is second to none, I would contact them directly as they can walk you through all of your variables (type of brass, chamber it was shot in, die settings, post sizing measurements) to give you the proper guidance and assurance.
 
+1 for it's normal.

+1 - with a Dillon; don't bother with the internet for answers - call them - you paid for the excellent support they offer - take advantage of it!
 
There's nothing wrong with using the Dillon dies. I have reloaded ~20k of 9mm so far, and all rounds that passed the chamber check worked fine. From a cosmetic view point, you could look at switching to Lee dies. I just started reloading 9mm for my S&W 929 revolver, and wanted a stronger crimp, so I switched to the Lee die set that had a "Factory" crimp die. The Lee sizing die that is included with the set resizes the brass on a taper, so the rounds look more like factory rounds. The only caveat is that I couldn't adjust the Lee resizing die all the way down to the shell plate. The rounds chamber check fine though.

The brass resized with the Dillon dies is above, brass processed with the Lee dies is below.

VanMan, when you say that the lee die doesnt touch the shell plate were you using Dillon lockrings or screwing the lee lockring from below the shell plate which usually compensates for the shorter lee dies on a Dillon press?

Thanks for the pictorial of the differences between outputs of the Lee versus Dillon dies.
 
I just decided to upgrade the 9mm dies for my 650 from lee to dillon and had the exact same result as you. I went back to lee dies and will never be buying dillon dies again.

I didn't even think of switching to the Dillon locking rings and putting them on the bottom of the tool head. That's a great tip and one of those "Doh" moments as soon as I read it lol :). It's hard to measure, but I'd say I'm .030 to .040" from touching the shell plate, and have about 1 1/2 screw threads engaged on the Lee die. I'll try switching the locking rings this weekend.

I'm probably going to leave the rest of my 9mm tool heads setup with Dillon dies. I have no problems using them at all through ~20k rounds loaded. I just wanted a stronger crimp for my revolver loads.

I removed the Station #1 Locator feed ramp for this pic

One thing I did find handy in the Lee dies was you can adjust and fine tune the seating depth and crimp without having to loosen up the locking rings. May come in handing as I'm starting to run different 147gr projectiles with different profiles (Campro rounded truncated point for semiauto, and Berry's round nose for revolver). I have a separate tool head & die setup for the Campro rounds now, but it may come in handy in the future. I'm wondering if they will move over time with all the constant cycling of rounds through them, so I put in a reference mark with a sharpie.

The first batch of rounds loaded last night. Dummy's I'll use for practicing speed moonclip changes.
