    Walnut will clean quick and leave a satin finish.

    Corn cob will take a little longer and leave a high polished shiney finish.

    Both work well, take your pick. Heres a tip tho, use a fine enough grit so it doesn't pack in the primer pocket or plug the flash hole. Not sure what grit to recommend for walnut but for corn cob I suggest 20/40 grit, cleans/polishes well and flows like sand.

    Here's a new outlet for corn cob and they have free shipping Also Graingers Industrial Supply.

    Walnut cleans carbon & tarnish way better the corn-cob.

    Corn-cob polishes to a high-gloss finish but doesn't clean as aggressively.

    I use both. Walnut first followed by corn-cob.

    I used corn-cob media for a while but it was to big, so I got walnut media from Harbor Freight and have not looked back since.

    Here's a similar discussion I had on another site: Alternative tumbler media: What grit/mesh?

    20/40 grit (or finer) is what was recommended for both corn cob or walnut. I've only used the "Lizzard Litter pet bedding" from Pets Mart with 2 capfuls of Nu-Finish car polish and cut-up dryer sheets. It cleans well, and if let run long enough (3 to 8 hours) polishes quite nicely too.

    I like to mix the walnut and corn cob about 50/50. I add a little Nu-Finish and cut up dryer sheets and let em whirl. Makes for some shiny new looking brass......

    Go to a pet shop (I use local PetSmart) and get a bag of walnut bird/lizard cage litter. The price is cheap and works great.

    A THR member posted about media (Corn Cob) at Grainger some time back. I bought some and that is what I use now. I used up the Walnut I bought to try. I don't foresee buying more unless I come up with a really badly tarnished bunch of brass. The occasional case that does not shine up is OK with me.

    I run a 60/40 mix of corn vs walnut, also follow the capful of liquid car polish tumbled in every half dozen cycles or so.

    Cut up used dryer sheets with every batch helps collect the dust.

    I just compared prices between Granger and Drillspot and found that granger was more than $40 after shipping and Drillspot was $20 with free shipping. Kind of a no brainer so I ordered up 40 lbs from drillspot. HAPPY TIMES!!!

    The corn cob kitty litter is a waste of money. It's not the same as corn cob blast media. Corn cob has three parts: the chaff, woody ring, and pith:

    [​IMG]

    Blast/tumbler media is made from only the woody ring part that (when dried) is harder than iron (on the Mohs' scale). It's also screened to give a consistent grit size.

    Kitty litter is unscreened (or inadequately screened) ground whole corn cob. It doesn't make a good tumbler media, it breaks down easily, and it will clog up your cases.

    How about a link?

    If you pick it up at Grainger, there is no shipping of course. $22.72 & $23.60 If they are out, they will order it for pickup from the store, and still don't charge shipping.

    I am lucky to work less than 3 miles from a Grainger. Only about 4 from the house.

    People who have bought it from Drillspot say it was drop shipped from Grainger!

    What works well for me is 20/40, you'll never have a problem with media sticking where it doesn't belong.

    And remember "never" is an awful long time.

    Here is a pic of the 14/20 I bought. I works great. I have to poke it out of few flash holes when tumbling sized and de-primed brass, but it flows out of .22 caliber cases with ease. The 20/40 is even finer. It should do even better as far as not sticking in case and flash holes.

    Never eh. That is a long time.

    I ordered yesterday and it arrived today!!! It was indeed dropshipped from Grainger. At first I was worried that I had accidentally accepted the order from grainger but the tracking info I got from drillspot matched the delivery label from grainger.

    I have been using corn cob media mixed with the Lyman Turbo Brite Brass Polish. The brass came out clean, but covered with a dark residue. I then started tumbling them a second time with plain corn cob media (no polish) to remove the dark residue. They come out of the second tumbler load looking totally new. With brass that bright it is easy to spot any flaws in the case. I keep one container of media + polish, and one container of pure, clean media for the second tumble.

    From Drillspot.com, 20/40 grit, 40 lbs. That is hard to beat; I ordered it yesterday evening & will see when it shows up. I live about 45 miles from a Grainger's in Columbia, SC, and tried to buy theirs on line, but kept getting asked for my resale tax number, no matter if I offered to pay tax.

    most likely they will drop ship it from the graingers that you live 45 minutes from.

    I use about a 50/50 mix of red Lyman turbo walnut media and plain corn cob, plus a few dabs of brass polish every once in a while. Never thought about dryer sheets but I do have lots of dust, so I'll be trying that. Learn something new every day - thanks guys!
