1. Make sure the edges of the slider (pointed to by the arrows below) are smooth.

If you can run your fingernail along the four edges and your fingernail catches then the edge is rough. Use some 320 grit sandpaper to smooth the edges Mine also had a small vertically-oriented ridge on one side that I needed to sand off. Check all four edges (both sides).

2. Squirt a little powdered graphite into the track that the slider runs in.

3. Both ends of the primer tube are not the same. One end is turned down and has a small shoulder on it. This end goes into the primer housing. On the small primer tube this shoulder is less visible and so it is easy to insert the tube upside down.

4. Examine the slider to see if it has been machined correctly in the area pointed to by the arrow:

On one of my sliders, it was as if the device milling the 'funnel' (for lack of a better word) and the device drilling the hole were not exactly concentric. As a result there was a small lip at the point of the arrow and the primer would catch on it. 2 minutes with a file solved this problem.

These are things to do if you have a problem.
Polishing and dry lube (I used Hornady's Cleaner/Dry Lube spray on the slider).
The same goes for the Dillon 1050 slider. This area HAS to be kept clean and free of oil, grease, dirt, and powder.

I had to tinker with the plastic mount at the top of my guide rod when I first got the press. I needed it to work then so I reamed the top bracket to make it work. I later called Hornady and they sent me a new guide rod fast and it turns out mine was out of spec. I had no additional problems ot of it until I switched to large primers. I was using wolf large pistol primers and the slide would hang up after a primer dropped. I finally took my chamfer tool and put a taper at the top of the slider where the primers drop. It is alumumn and did not take much. I have loaded a little over 3500 rounds so far with the press and so far I'm happy with it. I do have a running list of items that I plan to address when I get caught up with my loading. I need some shims for the bushing in one station, Large primer slider, small primer punch, and I noticed more slack in the in the carrier that the shell plate mounts to.

If it's not picking up primers you need to check the timing. Meaning how far back the sleds move. If too long or short you will have issues. This shows up as you start going faster. The addition of weight to the primer stacks help when the primers start getting low.
