I hope that this is in the right place. What is tumble media made out of?

Crushed wall nut or corn cob.

Crushed wall nut or corn cob.
...and then there are wet tumblers that use stainless steel pins.

Pet store lizard litter which is crushed walnut shells. Inexpensive and does a great job.

There are literally thousands of types and sizes of dry tumbling media. All you need to do to verify this is to open a McMaster-Carr or Grainger catalog and see page after page of them.

If you want to tumble your brass cases, then it's as the others have suggested... Corn cob is generally considered the best for light polishing, and walnut shell is generally considered best for removing serious discoloration. Or a mixture of the 2.

Lots of people add supplements, such as liquid NuFinish car wax, to their media to retain the results longer.

Corn cob sold as pet litter can be cheap and readily available, but is generally larger in size which can be a problem if used on small bottleneck cases, such as 223 Rem. This is not a problem with most pistol cases (38, 9, 40, 45).


You really need to try several types before you buy in bulk.

I like corn cob and a glob of car wax.

pretty brass comes out and it keeps the dust down.

Walnut works nicely as well I just cant find it as readily anymore but corn cob is available in my little town.

Just my 2 cents on this issue

I was out and had to buy the last container on the shelf at the local RipOff Central, and am the proud owner of 6 pounds of Lyman TufNut treated media, "crushed nutshells treated with rouge". It leaves a slight reddish tinge on the inside of the brass that has zero effect on anything, and leaves the outside VERY shiny...but I won't buy it again, too expensive and I don't need bright and shiny, just clean.

Reloader Fred posted this link a while back.

It's about the cheapest you'll find corn cob media in bulk.

Shipping is only $5.

Leaves your brass shiny and your fingers red. ;D

How long do you guys usually keep and use your media? I prefer 75/20 corn/walnut mix with Flitz tumbler media polish. Which I recharge every 5 or so batches.

I will usually tumble for 2 hours. I mix my corn cob with Mineral Spirits. Maybe 50/50. I add a cap full every time I run it until it's black. It still seems to do the job.

I like real shiney brass. I tumble for six hours. I use corn cob with a cap of mineral spirits and a cap of NuFinish polish and a old dryer sheet torn into strips.

I tumble for ~90 minutes and expect moderate results. (Clean, not necessarily gleaming.) When the brass starts looking so-so, I change out the media. The car wax is fresh for each load.

The great thing about corn cob is I can simply pour it out in the woods and not feel bad.
