Ultrasonic or Vibratory?

I place about two complete dryer sheet cut into 1" squares, loosely into the bowl with the corn cob media and 200 brass.

Before I place the brass into the bowl, I sprinkle abot a tablespoon of Charcoal lighter fluid in the corn cob media to vibra mix around to preven clumping...

The bag is only over the bowl I do some moly lubing in one of the bowls so I felt it necessary to control the dust especially when doing lead bullets.

Don't you have a lid on the bowl?

I use crushed walnut.  I find that when I forget about the tumbler and it runs for hours; the walnut breaks down some and there is a lot of dust when I pour the bowl in to hopper.  Which I do OUTSIDE while wearing a protective breathing mask.

And i do use a dryer sheet which turns black.

I have both.  I vibrated some 10mm that I bought at a gun show, then I decapped it and sonic cleaned.  I decided to use my heat gun to dry it.  I grabbed my wife's broiler pan bottom part and some foil and dried away.  It was going great until the foil started to rip from the sharp case mouths on the brass and the heat gun melted some of the residual fat that hadn't been totally washed off of the broiler pan.  Now the cases are all fat smeared.

In my defense, I'm a vegetarian...what the heck do I know about broiler pans??

Yes I have lid but being extra cautious with lead dust and air borne particles. Moly coated lead bullets are easy to work with yes a little messy but they run at lower pressures and I get less lead deposits in my barrel.

I just picked up an RCBS tumbler, RCBS #2 walnut media, RCBS lube and pad.

I thought you don't need lube if you're using carbide dies?

[Ramjet]

You do not but you have to have clean brass I just use gun scrubber or better acetone to clean them by wiping them off after tumbling.

[Yondering]

Not sure why you'd need to wipe them off after tumbling. Mine go straight from the tumbler to the reloading die, been doing it that way for years with never an issue.

I don't clean my brass after tumbling either.       That's why I tumble them, to CLEan Them.
