XL750 Tuneup and Tricks

Had my new XL750 press for a few weeks now.
And found a few problems, like most of the new users to the 750

There are primer feed issue's that are troublesome and annoying. But with Time taken to analyze them they can be quickly solved.

Problem:

1. Primer slide not going rearward far enough to pickup the primers from the primer tube.

Solution:
Bend the primer operating rod in two places where the factory bends are to allow the rod to push the primer slide all the way rearward.

2nd problem:

The primer slide is sticking on the primer feed body sometimes and some cases are not being primed, and this spills powder all over the press, Making a mess.

Cause: the large primer roller is dragging on the primer feed body.

Solution # 1. Bend the primer operating rod to the right in several places to force the large roller to ride away from the primer slide and the primer feed body when cycling the press handle.

Result: this worked well....

Better more permanent solution #2

I used an .250 Diameter Od spring with a .024 Wire diameter cut to length to put enough tension to keep the large primer roller away from the primer feed body.

did both solutions # 1, 2 together for a more permanent solution.

I think the # 2 spring solution is the best way but make sure you are not fighting the operating rod alignment being out too far, better to get this close first then use the spring to ensure the roller never contacts the primer feed body again. 😊

DILLON I HOPE YOU TAKE NOTICE TO THIS SOLUTION ESPECIALLY #2

In previous posts I talked about some indexing problems with taller Rifle cartridges, and case whip resulting in spilled powder when the case is nearly full of powder.

I installed a Delrin index ball in place of the steel ball used by Dillon under the index plate along with a Flat Torrington Bearing sandwiched between two hardened flat washers and installed between the shell plate bolt and shell plate,

I packed this bearing tightly with Lubri-plate grease and tightened to DILLONS spec

My shell plate rotation is extremely smooth, fluid like and comes to a stop like it has shock absorbers on it at each station. Shell plate wobble is non existent now. 😁,

Problem Solved:
I have pictures of the above mods if anyone is interested?


Lighting or visability while operating the press and seeing if your case has powder in it before topping with a bullet is hard without proper lighting.

I just bought a Hi intensity LED press light specifically made for the XL 650/750...press by... inIine Fabrication from Midway USA, will be here next week. Go online to .www.inlinefabrication.com.

The main LED light fits in the center toohead And is easily removable when changing toolheads. And there is a 6 LED strip that attaches to one of the vertical press sides too.

And Check out their product videos and reviews.

This solution is exceptional a bargain for 38.00 and has a lifetime warranty as well.

I have problem #2 with the large roller on the priming system. I like the spring idea, but I don't have one that fits the rod.
I tried using a spring you find in a pen, but too small. I cut and installed a piece of drinking straw to act as a bushing to keep the large roller from colliding with the primer housing. I wouldn't mind seeing the photos on the fixes you preformed. I'm going to get in touch with Dillon to see if there is an official fix for this. Maybe a small bushing like my straw idea or a spring like your idea.

Now that I've read some more posts, it looks to be an issue with the earlier xl750s going out. I'll call them next week and get this fixed.

I’d be interested in pics of your “better, more permanent solution #2”

I found it important that if you bend the rod the bottom part pushes the primer bar straight and not up, especially toward the end of the stroke.

RE: XL750 Tuneup and Tricks

New XL 750 owner here. Bought about a month ago. I've had nothing but issues with this press. First, it doesn't come setup in a caliber. They are just sending out a conversion kit. I've been loading on a rock chucker and a lee turret for about 20 years and have never had issues like I'm experiencing. Station locator one was damaged at delivery, Station 2 primer system works sporadically if at all. I've been experiencing a 25-30 percent failure rate. I'm really really trying to like the machine, but it has been frustrating. If its frustrating for me, then I can only imagine what a newbie to reloading must feel. I'll tinker with it till I get it right, but for what the press costs, these issues shouldn't exist. Just sayin' Customer support, when you can reach them ARE helpful, but overall... my $1k investment isn't currently working for me. I'm ready to send it directly to Dillon and have them re work it.

I'm sorry to hear your issues with your new press I've been using a XL650 set up for 45 acp for over 20 years with very few problems. The first of the year my wife bought me a new XL750 set up for 9mm and the only issues with it have been high primers caused by a loose shell plate and crud building up under the shell plate after loading about 12,000 rounds. I think once you get your machine set up proper and running 100% you will love it just keep it clean. Just last week I added a UFO light and a Mr Bullet feeder to mine and it works like a dream I just pull the handle and watch things happen. Good luck I bet you will be drinking the blue Kool Aid soon.

I've gotta say, I'm with lewmed - I ran about 100 9mm with it, stared at and tweaked any adjustments that were slightly off, bought the shellplate bearing and UFO light, and am off running with zero grief except that which I induce. Coming off quite a few years with a 650, so I didn't expect it to be clock-like out of the box.

I would be interested in the plate mods you made for a smoother indexing and less powder spillage. Pictures? Parts list? Whatever is available. Thanks.

RE: XL750 Tuneup and Tricks

I would love to get some photos if you have them, I am having the same problem when the case rotates it spill powder making a mess. I have tried contacting Dillon regarding this and keep getting told there is nothing wrong and I just needed to not fill them as full (this is not an optiion). If I could get things to run smooth I would absolutely love this machine.

Thank you,
