So i'm looking to prep some subsonic casings. I want to use a unique brand of brass for my subs. I have about 120 pcs of PPU brass but I had them all primed. I need to enlarge the primer flash hole to .094" so i punched put the unused primers with my LEE universal deprimer die. Is it ok to re-seat unfired primers or should you only seat primers once ? Thanks !
