Case Not Centering in Station 1

I usually have an issue with .204 Ruger cases not centering on the decapping die. Since they're nearly the same as the .223 Rem case, I don't make any changes to the shellplate, locator, or primer cups. I only need to change the toolhead. Even when I push the handle as far as I can to seat the case in station 1, sometimes it still doesn't center, and I end up with a broken decapping pin. Not hard to fix, just frustrating. I've tried adjusting the case insert slide and cam, as well as adjusting the camming pin. sometimes I can go through 40-50 cases before the problem occurs. I've cleaned the shellplate, as well, as sometimes lube does stick to the crevice on the shellplate. I didn't think there was much difference between the bases of the .204 and the .223, since they use the same shellplate and pins.

Did you ever get a reply from Dillon ?

No. Second time I've asked.....the difference in the diameters of the .223 and .204 aren't significant, and they both use the same shellplate and locator pins. All I have to do to change from .223 to .204 is remove the toolhead, put in the .204 toolhead, and move the powder reservoir over to the #2 station on the .204. There shouldn't be any further adjustments needed.....

To reliably get support from Dillon, you probably need to fill-out that Technical Support Request Form: www.dillonprecision.com/technical-support.html

There a really good video showing how to adjust that slide here:

If it is adjusted properly, there is a difference in how far the case is trying to be inserted when there is no primed case or no case being primed in station 2. If the case is trying to be inserted too far, it can then spring or wobble backwards. Being aware of this can help you be alert to the possibility.

If you have one of those aftermarket roller cam followers, be aware that they are not infinitely adjustable because the little bearing wheel needs to be in line with the slide travel. Since there are 24 threads per inch and two positions available for each rotation of the follower, the minimum incremental adjustment in the length of the follower is close to 0.021". Since the slide has about a 45┬░ angle, that 0.021" vertical step translates into the same amount in the horizontal direction. So, with the roller cam pin, adjustments can only be made in 0.021" increments. Food for thought...
