crushed primer

I have a question. I have just purchased a Dillon xl650 press I have ran about 700 9mm rounds through the press with no problems. I have started another batch, powder, primers, shell cases nothing has changed. Here is were the problem lies about every 5 shell primer is crushed, its like the primer seat rod is almost splitting the primer, I can feel the resistance and I stop and sure enough its already damaged.

I have taken the primer assembly apart and cleaned it nothing a few scratches on the indexing plate nothing major, were the primers rest on the base I noticed that it was a little rough due to the casting process again nothing to rough so I cleaned and polished it. Put everything back together and dry ran everything seemed fine again nothing binding. Loaded 10 primers and indexed the machine until I seen the primers in the seating rod ran another 5 primers through just to make sure everything was working correctly. Loaded another 10 primers in along with a handful of shell. Everything seemed fine for 5 shells then on the 6th shell felt resistance and again crushed primer. So again took everything apart. I did notice on the primer dial plate that it look like there was a little contact with the priming rod and the plate cleaned it up and flipped the dial plate reassembled everything and again the 6th shell crunch. I have read all the posts and the manual and tried to adjust what I could everything seems that it still hits on the 5th or 6th shell. I have tired different shells different primers its still does the same. I was looking at the primer G.S Customer primer on ebay maybe see it that will work. I am open to any ideas I really like this machine tons better that single station.

2 questions

1. By any chance are your casings military? The only time it happens to me is when one gets mixed in. Sometimes they'll load but most of the times they don't. You can tell military brass because it won't normally say "9mm Luger" on the headstamp, I separate these out and when I get enough I run them through my primer swage 600.

2. What primers are you using? I've only used CCI, Winchester, and S&B, could be some bad primers.

The reason I ask these 2 questions is that I load ~1200 rounds a week (every week) and the only crushed primers that I've experienced is from military brass, but I have heard that some brands of primers have this problem (never experienced it personally).

Good luck.

I concur. It sounds like you have some military brass with crimped primer pockets. What is the headstamp on the cases where primers crushed? If it does not state the caliber, or if you see a circle embossed in the case head surrounding the primer pocket, then you have crimped in primers. The crimp needs to be removed using a swager, then it can be reloaded.

No military head stamps I checked and double checked after everything I read that was the first thing I checked thought I would get off easy

Primers are Winchester the same ones that I used for the first round of shells. Also tried CSI and it did the same thing.

Also I broke down my machine again and used almost all the parts on the maintenance kit for the primers and still did the same thing this time about every 14 to 16 again took apart the primer section and notice that the primer  pin looks like it has been rubbing on the primer plate about every 8th hole. That's the only thing that has in common is the primer plate. Also just for fun I had my Wife run a couple of rounds just to see if she feels the same thing and sure enough crunch.

Just in case you are still have same problem...

I don't load 9mm brass in my 650,but I've been loading 38 special and 223 cal. for years now, and have had, and still do sometimes, (Rare ) crushed primers. 

 (plate was to tight ) I lost a lot of good primers until I turned  back the shell plate bolt about 1/8 to 1/4 turn which gives a little loose  play when seating each primer. Being careful and feeling each primer seating, everthing seems to work better. Hope this helps, it has for me. ps. keep it clean and lubed

If not military brass, then it sounds like the shell plate is no longer lined up with the priming station.  Check if the platform for being tight or out of alignment with shell plate.  If out of alignment then call dillon for alignment tool.

The 13242 Primer Station Locator Tab might not be fully pressing the case into the shell plate.  Slow down at primer seating station and feel for primer not pressing in smoothly. Stop if not pressing in smooth. Wiggle the shell case while pressing handle for priming.  You should be able to feel when the primer starts to slide in. The Primer Station Locator Tab may need to be adjusted to press the shell case in the shell plate.

By slowing down the handle return at the primer seat you should be able to save from any crushed primers and not lose any time with re-manufacturing rate.

I just had the same exact problem this week with 9mm. I separated the military brass out as well and then from a suggested from Dillon I bent the locator tab in just a little. Just enough to keep the Casing still while the primer seats. Mine is working perfect now!!!

'I bent the locator tab in just a little.' .. there is an adjustment screw for that.  See Figure 194 on page 39 of the owners manual.  You should not have to bend the tab.

I know - I saw the adjusting screw but I could not get it to turn at all. I would much preferred to turn the screw but the guy at Dillon said it may have gotten bent after my mishap and suggested I Bend it in just a tad. It seems to work great. Is the screw turn from behind the locator or do I need to take of the arm in order to get to it?
