Has anybody else had a problem with the primer system on a 650? My problem is with the arm that jumps hole to hole to advance the primer shell plate, the arm doesn't make it in every hole and I might have 4 or 5 or more rounds that don't get primed because of the primer shell plate not indexing. Anybody have an idea what's going on?

Is your downstroke all the way to the stop? The primer tray rotates on the bottom of the downstroke as the lever passes the black delrin block mounted to the front of the press.
If your stroke is full, then is the primer index lever stuck? Do you have some crud (powder, dust, etc.) clogging up the tray? I know my plate gets cruddy after 3-4k .45ACP run through; left over media, lube from the press itself, dust, anything else in the air, dust from the spent primers, etc.
The lever should click and spring back instantly - if there's any stickiness, it's time to clean/maintain. -

I took it apart to see if there was a piece of stick powder or media or something in there which there wasn't. This is a new press, I haven't even completed 200 rounds on it yet. The press did a good job on my 40 S&W but I did the caliber conversion to 223 and got through the first 50 fine then noticed my rounds were "completed" but after inspecting noticed there was no primer. I will take it apart today and clean it much better than I did last night now that I'm confident in how to assemble and dis-assemble the primer head.
It seems to run better with no primers in there than it does with primers in there.Last edited by bearstatearmory.com; 10-21-2012, 6:28 AM.Comment

This same thing happened to me when my press was brand new.... When I switched from 9mm to 10mm for the first time and took it apart and cleaned it, now runs flawlessly ever since....
When you take the primer assembly off, compress the arm a bunch of times and break-in the spring.... might help tooLast edited by MIAMIbaseballer; 10-21-2012, 6:41 AM.It's ok to be jealous.

I've had a 650 for several years and do not use the priming system. I trim and size on the Dillon then do the case neck and priming by hand (RCBS Green Machine and hand priming tool). This way I can inspect each case in hand and confirm that each primer is right. This speeds up reloading as I only have to fill the powder and put on a bullet as I go. Longer prep time but safer ammo and faster final stage. I also use the powder check on all my toolheads to ensure they have a semi/correct powder charge (They are not 100% accurate per gr, but let you know if you missed or doubled a charge).Comment

I was having the same problem and mostly fixed it.
I told dillon and they sent me some parts
I greased the black wedge that scrapes the lever to kick it to the next spot
I dry lubed the indexing parts with silicon dry lube
I started using another brand primer (cci)
I did a few other things to the press but that mostly fixed it. Now if it gets dirty I just clean it and it works again.Comment

happened to me. Was a little powder grit in the area that has the "bent washer" type spring. Clean and you should be all set.On a long enough timeline, the survival rate for everyone drops to zero.Comment

I got some new parts from Dillon and had the same results/wasn't satisfied. I then took a spent primer and put it behind the spring so there is significantly more pressue on the arm and it works awesome. I think Dillon should look into making their spring just a little bit longer to increase that pressure on the arm that advances the primer shell plate. Back to reloading tomorrow.
