Primer Assembly

Page 1 of 2Next

Does anyone have an answer regarding how to keep the Primer Assembly running? I have loaded thus far, 400 rounds of 9mm and 300 rounds of 10mm. In my humble opinion the Primer Assembly is the weak link in the system. Usually I couldn't make it much past 10 reloads before the Primer System would get jammed. The jams were from the primers getting turned on end, or levered upward against the primer wheel, stopping progress cold. I've about decided to prime the brass by hand then run it through the 650. I hate priming by hand, but I hate the primer Assembly more for stopping progress.

Make sure your primer assembly is secure to the base. It sounds like it's loose or you might be using the large primer system where you should be using the small primer system?

If any lubricant gets into the holes of the primer wheel, it will cause problems.

Be sure you swap the primer discs, punches, and primer seaters when changing primer sizes.

Thank you for the replies. There is no lubrication applied to the primer system. The large seater assembly was used on the large primers and the small seater assembly was used on the small primers. There is space to the side where the primers stack and fall into the hole as it rotates under the primer. Invariably, when I take the primer assembly apart there are on or two primers jammed in there, and usually 4 primers fall out as soon as the wheel is freed. Many times I have had primers folded in half in the hole they dropped in. I have had primers come up to the seater assembly, and because it failed to retract all the way, the primer rides up and gets crushed between the wheel and the seater assembly ram. There is no way this XL 650 and this primer assembly will ever achieve 500-600 rounds an hour. I feel fortunate t get to 50 ir 60 rounds in an hour. And, when I put the primer assembly back on, there are two large bolts and I am probably applying 40 to 50 inch/pounds of torque. I don't want to strip out the threads in the Platform Assembly. Once again, on Sunday 3/19, I had to take the primer assembly off, and dang it if the detent ball didn't jump free. I've gotten my gun room cleaner than it's been in 15 years looking for that detent ball. I called yesterday morning and Dillon was supposed to have another detent ball headed my way. Hopefully I'll get it tomorrow. I bought and installed the Dillon Automatic Case Feeder. On the SLOW speed it's dropping 1 case a second. There not a chance in hades of keeping up with that - that would be 3600 rounds per hour. I guess I keep an eye on the feed tube and when I need more cases I just hit the button on the Case Feeder. At least IT works. I'm getting ready to shell out some major cash for a stand alone primer that looks like I can prime about 1000 cases in an hour when I get used to it. Plus it can be used as the most precise primer I've seen. I don't need that kind of precision on pistol calibers, but I do need it on my custom rifles.

I'm buying the stand alone primer because I'm going to prime the cases THEN put them in the case feeder and just bypass the weak link in the loading system, the Dillon XL 650 Primer Assembly, which as far as I'm concerned does not work properly.

Make sure that you have the correct primer feed tube installed. If using the large tube with small primers it may be possible that the small primers get turned on their side when inserted into the feed tube.

I do use the correct primer magazine to pick up the primers from the flip tray. Small magazine - small primers; Large magazine - large primers. I promise, it's not anything I'm doing wrong. I don't know if the Primer Assembly is one that came off the line out of spec, or I just have rotten luck. I tried Federal, Winchester and Sellier & Bellot primers in both small and large. I would have tried Remington primers if I had been able to find any. Although I doubt seriously that the Remington Primers would solve the problem. It's a systemic problem.

I believe dfreeman was referring to the primer magazine (18L / 18S on the parts diagram) inside of the safety shield (#17) - not the pick-up tube. It is also important that the knurled cap (#1) on the primer safety shield be snug - not too tight, just snug, to insure the proper (minimal) clearance between the bottom of the magazine tube and the priming disk.

Yes I switched those out as well. Large Primers Large Magazine, the part that is inserted in the primer shield. I even turned it over and used a small screw drive to keep the bottom of the magazine centered, because it could move in several direction that made the opening look like a waning moon.

It's not me. None of you guys are suffering from this apparently, so Dillon should exchange a primer assembly with me. I believe it's the Primer Assembly. All the questions you guys asked are great questions; they are the same questions the Dillon Techs asked me when I called in 5 times now. The only solution any of them offered that sounded reasonable to me was that certain brands of primers are too soft, some are out of round, some are like snowflakes, no two primers are the same. The Tech that said try a different brand of primer told me he liked Sellier & Bellot. I got some via UPS and the very first magazine full jammed immediately. That's when the detent ball (which didn't arrive today by the way) took off on me. I had primers going everywhere, and the detent ball slipped through my grasp.
