How do I clean up old ammo?

An unchambered round that would go off in a tumbler would just make a mess IMO.

That's what I meant: it could make a mess. A really bad, wet, stinking, charred, can't-believe-it-happened-to-me, so-much-that-we'll-never-be-able-to-repace mess.

Launching rounds from a vise is nothing at all like burying a live round in combustible material and then igniting the thoroughly mixed gunpowder.

If you're going to do it, do it outside, on pavement, well away from the house and shop. Why take the chance on burning down your home? Call your favorite tumbler manufacturer and ask their opinion. Better yet, call your homeowner's insurance carrier and ask if you're covered. You know, just in case?

The manufacturer is going to cover his butt and say no, for liability reasons.

To each his own, I tumble live ammo.

I have heard of the concern of a possible primer strike while tumbling (unfounded...its a vibratory tumbler...not a clothes dryer) also the degraded powder concern (also disproven by many tests...the manufacturers even "tumble") first I heard of being concerned over bullets falling out though. I'll keep an eye on my crimps.

Biggest recurring problem I know of when tumbling live ammo is getting pieces of media out of hollow point pistol ammo.
