I received an RCBS case tumbler for Christmas but there aren't many directions on how to use it. Should I lube, deprime and resize the cases and then run them through the tumbler or should I clean them and then start the reloading process? Also, I have both walnut shell media and corn cob media and also some polishing compound that came with the media. Which media should I use?

Thanks

Deprime first. The priming residue is abrasive. If I'm going to clean the brass anyhow, I don't want to get the grit and dirt in my resizing die. A universal decapping die is handy for this.
I prefer the walnut media.

I inspect my cases thoroughly, and remove any grime. I thenpreform casepreperation as needed, and last tumble them. I next prime, charge, and seat the bullet.

The walnut shell is used for cleaning, and the corn cob with polishing compound is for polishing. Good luck.

If I lube, deprime and resize the cases and then clean, do I need to relube the cases after cleaning? Or will the bullet seat okay without relubing?

No need to re-lube cases for the bullet seating operation.

That's the reason I like to tumble the cases after I work them is to remove the lube. Most lubes can contaminate primers and powder causing a miss-fire. Good luck.

Itumble my cases first, then resize. I want 'em nice and clean before going into the resizing die.

As far as media is concerned, I preferWalnut. Itworks a little faster and shines the brass just fine when a little Flitz is added to it.

Once fired I tumble the brass to clean the brass before resizing and depriming. After lube and resizing I wash my brass in simple green I have in a 5 gallon bucket, rinse and let dry. Re tumble, also check the petsmart for corncob litter, it's larger in size and I mix it 50/50 with tumbling media.
