I dug around a little and found I had a suitable rod for the primer pocket swage die .
I had to make a "pushrod" to get full primer rim contact on the shotgun primers.

I had gotten a batch of Berdan primed 303B and straightened them .
I have most of a carton of shotgun primers that haven't had a case made for them since about 1974 . Now I have 37 brass 410s that use Rem #57 or 109s . KIMG0028~2.JPG
