Lee sizing die leaves scratches on 9 mm brass, how safe ?

Theoretically true, but you'd have to run Flitz on a cordless drill for a loooong time to change the dies dimensions.

Varmint Al says he does it for 30 seconds and a test on a mild steel rod showed no measurable change after 2 minutes at 500 rpm...
