Priming system problems

Some of my problems may be just learning the new priming system. Some of them may not be. I have an XL650 and have few issues with it. I just received an XL750 today and I got it set up and started loading 9mm. Initially, I was having issues with the primer not wanting to seat into the pocket. An adjustment of the indexing roller fixed that. But now the primer slide does not want to slide all the way back to pick up a new primer. I have to finish the slide by hand. And then when it goes to slide back in to place the primer for priming, the roller whell gets caught on the end of the primer slide platform and I have to pause and move the wheel to the outside before the primer slide will go forward. Not sure I like this new priming system.

RE: Priming system problems

OK. So today I took the priming system apart. I rubed the slider and the channel it slides through with 0000 steel wool. I cleaned everything with alcohol and then lubed it with Otis dry lube. I checked operation while it was apart and the primer cup goes where it is supposed to. Re-assembled it all and took a look at the guide wire. I ended up bending it slightly in 2 directions and put it back on. Now my priming system does full travel both ways uninterrupted. I loaded up some primers and loaded up some rounds and there was not one mishap.

RE: Priming system problems

So let me understand this. Dillon sold you a product that didn't work out of the box, that you dropped big money on. But you fixed it after hours of work.

Send Dillon a bill. I think your time is worth a good minimum wage per hour at least.

RE: Priming system problems

Probably get you a new DILLON HAT.....but SERIOUSLY.....here is the FIX for the Priming issues.

DILLON HAS REDESIGNED THE Wire Form (Link) and the Upper (Small) Guide Pulley. Mine did the same thing as the original poster.

It is NOT a matter (at least on mine) of honing and smoothing....it is a running design improvement.

Call and tell them. The early XL750 had this issue. You get a NEW Wire Form and a NEW Upper Guide or small pulley.

The feeder or shuttle works FINE. BUT the lower guide pulley will be oriented or maladjusted to the LEFT. That pulley bangs against the side wall of the primer feeder housing.

I bent MINE TWICE. When you push in the wire form (link) at the top (the mounting or holding bracket), the wire form stops or rests against a small stop or ledge. With finger pressure on the Wire Form......now LOOK DOWN at the small Pulley or guide. It is PROBABLY NOT centered on that guide. In addition, the lower pulley is pushed to the LEFT....so it bangs into the body and does not feed or index correctly.

Tech told me today.....Don't BEND.....new parts coming and then check the alignment. The upper guide has the contour changed. Will measure mine....if the installed one is different, then will change it. Sounds like they changed ONE part and that did not correct it or they realized it was a TWO stage issue.

The OBJECT is to have the lower pulled almost to the RIGHT or in a position where there is plenty of clearance as the feeder shuttles in and out.

Other than readjusting the drop down cam follower (Pencil shaped rod on station ONE, it is coming along.

DID find out that you need to really BANG IN and seat the plastic insert or adapter that holds the shells. Mine was not seated and the shells were hanging up. Seated that FULLY with a small rubber mallet and feeding is now 100%...

Are there any problems with the new dillon XL750? I am undecided to buy the dillon xl750 or the old xl650.

RE: Priming system problems

Dillon no longer manufacturing 650. They will support it and continue to have parts specific to it, so unless you want to buy a discontinued item, the 750 is current model.

I have done a LOT of reading and spent hours on the phone with
Dillon support BEFORE I purchased. They were candid about the issues with the 650 and addressed them in the 750. Also talked to a lot of Dillon owners of Square Deal and 550 and such. These were 30 year DILLON customers and they cautioned about the changeover and adjustment and reliability of the 650 priming system.

Folks love, as well as hate, the 650. Primer system was weak link and Dillon abandoned the design and went back to the more proven and robust 550concept.

Now...if you don’t mind issues of changeover or only load one particular primer calibers or don’t plan to switch from large to small, then the 650 might be a good choice.

The fact that they dropped it and discontinued manufacturing should be a clue....

Once I figured out what was wrong with the wire form design and temporarily rebent mine, it works flawlessly.

RE: Priming system problems

The XL750 is my first press...ever. I’m rethinking on even keeping it. Was super excited when it finally arrived. Mounted it, set it all up per instructions(not very good ones if you ask me). Set up the dies, had it all locked down and set, ....then added powder and primers. That’s when my trouble began. First few that I did one at a time seemed ok, although some primers were kinda rough to seat. Then it became really sporadic. Trusting that I could start loading progressively, I quickly had a powdery mess on the index plate. No primers. Stopped and started doing just one at a time, thought I had it going again, then the primers were getting crunch and put in completely sideways. I’m very well aware of NATO crimped brass, so that was not the problem. Other issues during this was the brass not loading all the way on the shell plate and hanging up on station one. Some do, most don’t. Same thing on the powder station. Definitely flared it, and wiped out several good pieces of brass on one side if it. Again, sporadic and inconsistent. How is this happening??
I’m not like most of you, I don’t know these machines top to bottom, so I don’t know what to do. Between inconsistencies on stations one and two and my machine not pruning at all, I feel like I need to fly a Dillon tech to my house. Any pointers or anything at all to make me feel like Dillon can take care of this would be appreciated. Hate to return it. Spent a lot of time and money to prep this even before investing in the equipment

RE: Priming system problems

Cases are fully seated into the shellplate when you push the handle forward to seat the primer. What caliber are you loading? What is the headstamp on the cases that didn't prime correctly?
At station 2 is a wire spring. Be sure this is applying light pressure to the case, to hold it into the shellplate.

RE: Priming system problems

Damon,

Here is what I have done and I now have very few issues. This is MY first Progressive and we are in the same boat. It IS a learning curve. BUT after a lot of tweaking, I ran over 500 tonight with NO issues...CALL TECH SUPPORT.....and they will go THROUGH each step...

Mine is a 9mm....so maybe you are having other issues....but here goes.

Station 1. Had to adjust the long black nylon rod down against the cam. Tech Support will walk you through it. Mine was way off. Therefore the shells were not going all the way over and the decapping pin was hitting. What you want, I figured out....

When you move the handle forward (priming stroke) STOP THERE. NOW take your finger or a screwdriver and see if you can move the shell FURTHER to the LEFT or into the shell holder. IF SO....then keep moving down the rod.

once you are close.....then push up and put the shell in all the way with the shuttle. NOW....do the opposite push. Hold handle UP. Use left hand or screwdriver or finger and push horizontally on the BASE or bottom of the case. Should be maybe 0.020 or barely moved. I have run mine down a little since the tech said it "OK"" Now shells seat properly.

IF you have SHELL dropping problems like I did, there is a little shuttle or cast piece that swivels back and forth under the shell drop tube. Allen screw on the outside. BACK that out so you get more MOVEMENT....IF THE SHELLS DO NOT DROP.

Station 2.....PRIMERS. STOP. You need the UPGRADE wire form and the small (upper) pulley. Dillon will mail to you. I bent mine after I figured it out. NOW....my issue was NO PRIMER FEED....in other words, the larger white pulley on the slide or shuttle was hitting the side of the primer slide housing. IF you look at where the wire form is when the arm is fully extended (top of stroke and push forward)....PUSH the wire form to the LEFT in the top block where it is hinged. There is a Ledge or stop there. When you push it to the left against the stop.....if you follow the wire form down....it is banging or trying to bang into the housing. That pulls the larger pulley OVER and it hits. Mine works great now after two "adjustments", but I will install the new parts.

PRIMERS....I had "indents". With NO primer in the holder, push the handle FORWARD (prime position). Look on the TOP of the primer punch. Mine had some "Debris" or gunk on it. Scraped off with my fingernail. BOTTOM LINE....fixed that.

Damon, IF you are reloading Pistol cartridges.....go to Amazon and order the LE Wilson case gage. I used that.

I ran the sizing down until it almost touched the shell plate. THAT fixed "Sized" cases will not drop into gage. Set it up like a single stage where the sizing die has just a smidge of daylight....say 0.040 or so. You want FULL LENGTH sizing.

Same thing for the CRIMPER. Measure the crimp. On your SHORTEST case, it should be 0.010 - 0.012. THEN when you crimp.....use the case gage. I was afraid I was OVERCRIMPING. NOPE....under. The completed cartridges would not drop in to the gage. i kept barely cranking it down. BINGO. Works like factory ammo now.

I have spent over 10 hours on tech support.....one problem at a time. RUN a few....try to noodle it out....then call and they HELP>
