I am trying to size Speer 357 Sig cases and my RCBS depriming pin will not punch out the primer. What gives?

  You will run across certain brass with a under size flash hole. If you just have a limited amount of them, toss them in the trash. If you have a lot you want to salvage, manually punch out the old primer with sharp pointed scriber or a pin punch. Open up the flash hole with a #48 drill.

  Thanks! I have a lot so I will go with option 2, punch them out and then drill. I will also call Speer to see what gives....they are Speer cases.

  Actually there was a 3rd option, better than a or b. I called RCBS, they said they would send me a new decapper unit with a smaller decapping pin that will work in the Speer cases.
