How do you get the dents out of the primer? A brass punch?
I would either use punches of the right size or I was also throwing around the idea of taking an old shell holder for a single stage press and having it filled in and welded and then smoothed flat. Then use a flattened pin in a Lee universal Decapping die and press the dent out like an arbor press.
I’m trying to figure a way to get the anvils back to the correct shape. And then, there’s the primer compound I have to research.
