Dillon 650 xl help

^^^^ that part. At a minimum, this results into unseated and flipped primers. At worst, this can result into a primer kaboom.

Solution, center the primer to the shell plate. I don’t have a unit in front of me, but if I remember correctly, this can be addressed by adjusting the indexer block or calibrating the platform (require free tool from Dillon). Calibration is only necessary for units that are older or ones disassembled outside of the factory. My memory ain’t the best.

If #3 is the issue, when doing caliber changes, check if the case is pushed to seat on the shell plate properly. Otherwise, the primer hole will not align the the primer seater.

I thought you only needed to calibrate the shellplate platform (with the Dillon tool) if you had removed the shellplate platform.
He said he replaced the primer system.

Replacing the primer system does NOT require removal of the shellplate platform.
The priming punch screws into the bottom of the shellplate platform so moving the shellplate platform around on the ram does NOT change the alignment of the primer punch in relation to the shellplate platform/shellplate/case head.

A shellplate indexing problem would make the primer seating punch be misaligned to the shellplate/case head.
A primer disc indexing problem would mis-align the primers to the seating punch.

^^^right on the primer system disassembly.

In troubleshooting, sometimes, problems are caused by factors unintentionally undisclosed. I described other solutions which may help solve the problem if caused by other factors.

For example. I’ve also seen a situation where the weight of an upgraded ergo lever and handle caused the shell plate to move forward just a tad to misalign the primer to the shell plate. A shim under the primer seating spring can help resolve the issue.
