De-primed?
Who cares. All you need is a steel rod that fits tightly in the neck, and some water. Fill case with water, insert rod into top of case, wack with a hammer, and watch the hydraulic action deprime your case.

I've never had luck with that method with the pile of SA surplus I have with it's staked primers. I'm confident that different brass will behave differently, but to me, it's not worth the risk.
I also have experienced similar results with the RCBS tool.
I never had any luck holding the case and rod in one hand and bonking it with the other hand.
I found the case and the rod go different directions...
I do have complete success by thumping the water filled case up into the sizing die in the press.
NOTE! THE CASE MUST BE RESIZED FIRST, AND THE DECAPPING PIN MUST NOT BE IN THE EXPANDER BALL STEM.
You must remove the decapping pin for Berdan anyway, and the cases must be pre-resized before slamming them into the sizing die to hydraulically decap them.
Otherwise, you WILL have a stuck case.
