Dillion XL650 depriming issues

[bbooker]

I am having problems with my XL650 depriming 9mm brass. It is not pushing the primer out in about 1 in 10 cases. It is a Dillion die with about 7-8k loads through it. Mixed head stamps. It just started all of a sudden. Here is what I have checked:

Die is as far down on shell plate as possible.
Installed new pin in die.
Inside of die is clean.
Checked case length on brass that failed to deprime. None exceed max case length in my reloading manuals.

I have no idea what to do other than purchase a new die and try that.

Any ideas?

Is the brass entering the depriming die all the way? Crimped primers? If you try and run the piece of brass thru again, does it work the second time?

Broken rod would have been my first thought, but if you've changed it.

If you can't adjust it out or find a broken pin or what the problem is call Dillon and they will walk you through it. I have had this problem but it was due to adjustment of the die or decapping pin. Swaged cases can be a problem but these are usually 5.56.

Sounds like crimped primer pockets to me, but since you said it just started happening, I'm clueless. Did you just start reloading some range pickup brass?

Like the other poster said, call Dillon.

All the brass is from my reloads.

Dillon dies have a spring loaded Decapping Pin. You should be hearing the pin spring pop as you decap.

Should be screwed all the way in, like the first two photo. The pin should not be capable of being adjusted too long, as the spring system will compensate for any extra length.
Not like the third and fourth photo.
Last photo is a functioning Decapping Pin.

What are the chances the spring is wore out or gone bad?

Pull the decapping pin out and put a little taper on the end of it. If the decapper gets some mileage on it, the tip will flatten out a little and give the spent primer something to grab onto and it won't flick off. As the pin comes out, it'll draw the spent primer back into the case.

Is the spent primer pathway clear?
