how do you de-prime?

[Magellann]

I use my single stage press for depriming, Then reload on the turret press.

Lee universal decapper in a single stage press.
Then I wet tumble because I like clean brass through my dies

That's my main reason and being able to see any damaged brass easily

I deprime on my press as part of the sizing. Then I tumble to clean off lube and clean the pockets a bit.

Same. Not that I've really experimented with it though, it's just always how I've done it.

I'll tumble the brass after depriming to keep the crud out of the dies. It works for me.
