deprime punch drags

I began to load 30-06 for the first time on my Super 1050. I'm using Dillon dies. When I adjust the sizing die correctly to give me the correct shoulder location as per the Dillon case gauge, the deprimer punch drags on the case mouth as the shell plate tries to advance.

I checked the deprime punch to make sure it was the correct unit by comparing it to my spare part. The only way I can get the shell plate to advance without the case mouth hitting the deprime punch is to unscrew the stem until it only catches by perhaps 2 threads. Then I have the needed clearance to let the shell plate advance.

This is the first time that I have used this set of Dillon dies. The threaded part of the deprime stem is the same size as the one in my Dillon 308 dies.

What am I doing wrong?

Thanks for the help.

RE: deprime punch drags

You are indeed adjusting the depriming assembly correctly. Due to the shorter stroke length of the Super 1050, the depriming assembly must be backed up higher than the factory setting.

I thought the Super 1050 had a longer stroke than the RL1050?

It does. The RL1050 lacks enough stroke for 308 Winchester, 223 Remington is the tallest you can load on the RL1050.
