Wash-ar15 · 12-11-2009, 14:35

which one should i get for tumbling brass??

Boxerglocker · 12-11-2009, 14:57

the Grainger stuff is good... one of the local shops buys it bulk from them and rebags and sells it in 7lb bags. I believe it's the 14/20 they sell.

jawjaboy · 12-11-2009, 15:39

14/20 for sure. Just bought a 40 pound bag from Grainger this year, under $23. Best cob media that I have ever used.

Thanks.

No problem Wash. Order it from your nearest Grainger store, pick it up there and shipping is free. Good stuff at a great price, for real. If ya don't need 40 pounds right now, split it up with others.

Where can you get it from?

See post #5.

I am in no way affiliated with Grainger, FWIW.

Like Jawja says, the 14-20 grit is the way to go:

No Grainger here, didn't know if someone else carried it.

I have a hard time believing there's not a Grainger in DFW. Grainger's site appears to be going nanners right now, but what about this one..

Edit: FWIW, their site came up and I did a search... There's 3 in Dallas and 3 in Fort Worth, and 1 in Arlington if you happen to be between the two.

That stuff looks small enough that it won't have the problem corn cob pet bedding does of getting stuck inside 9mm cases. I may have to pick some up. How many 5 gallon buckets worth is 40lbs? Just wondering how much space it's going to take up.

DFW is a big place so unfortunately downtown Dallas and Arlington are at least an hour away. However, I was able to find a suitable substitute. Petco can order large bags of Zilla Litter which is a fine grind of black walnut hulls that they use for reptile litter but will work just fine for the tumbler. The price was also very reasonable.

Don't know NJL. I have my half bag stored in one of those big square plastic storage boxes. Surely less than 2 buckets for an entire bag.

A pic of the bag is in the below link.

And in case you end up with more than you can use ...... you can use it to smoke fish and other meats! I actually learned of using corn cob for smoking long before I began reloading, thanks to a commercial fishery up north from me.

RustyFN · 12-12-2009, 16:43

Is there anything wrong with using the 20/40 grit?I just ordered a bag of it but can probably exchange it if I have to.

When I first read this I was thing of personal use like I did on the farm as a boy. I also know of a use for whole corn cobs after the Sears catalogs ran out.

Where are you at in DFW? There are about a dozen in the area. I can point you in the right direction for future reference.

update!! got my bag this morning. Strange to be so excited over a bag of corn cob!!LOL

First thing I noticed was it was a lot finer than what I have been using. comparing it to my old stuff,my old stuff seems to be walnut.

I noticed that where my old media would swirl in my Frankfurt tumbler,it now cascades.

I threw some 223 brass in it to test it.

wish me luck

It really is the little things in life that are the best. Let us know how the corn cob rates against the walnut. I use walnut and can't imagine the brass coming out shinier that it already does.

RustyFN · 12-21-2009, 15:23

I got my bag also. I was able to exchange the 20/40 for the 14/20. I couldn't believe how much you get for $21. It filled three cat litter buckets. I can't wait to try it.

njl · 02-24-2010, 16:01

Argh...I finally got around to calling Grainger, asking them to get the stuff (they don't stock it at the nearest location), and they got the wrong size. I asked for the larger size, and they ordered the larger number grit size, which is smaller particle size. I guess I'll call tomorrow to see about getting them to order the 14/20 and exchange what I just picked up.

The 20/40 sounds like it's going to be way small for brass tumbling. Anyone tried it?
