Corn Cob for cleaning brass




I cannot find the information where I bought my last batch of corn ob media. Can any one please give me a supplier for Corn cob at a reasonable price and what is the grain size?
I know you can get it at the gun supply stores, I am looking for a supplier of abrasive for cleaners in bulk. Not looking for Cabela's and the normal places.
Thanks

Any pet store has both ground corn cob and ground walnut shells. I purchase a large bag and it last a few years.

I got some corn cob media from Pet Smart and used it one time. The pieces were so large that they packed into bottleneck cases and had to be picked out. I assume corn cob media cut into smaller pieces would work better. I have gone back to walnut shell media.

I have not been able to find walnut shell lizard bedding but have heard that it is fine enough so that it does not lodge in the flash holes. The walnut media I have at the moment leaves lots of chunks stuck in the flash holes.

Some of the larger walmarts have corn cob media in the pet aisle very reasonable.

Petsmart lizard bedding like 12 bucks for large bag. Mix with 2 ea (quartered) drier sheets and one table spoon car wax (I use turtlewax because thats what I have on hand) some like Nufinish...tumble till shiney (about 2-3 hours) de-cob and ready for inspection then reloading...

The 20/40 grit in the post from Jrdavidson above works for me. It will cone from Graingers Supply most likely.

I've used the same corn cob medium for over two years and more than 10,000 cases. I don't think $10 a year is too much to pay.

It takes very little abrasive to get the job done. I mixed in about a tablespoon of white (cerium oxide) paste at the beginning, and another teaspoon at intervals (two or three times) when it lost its oomph.

To much work, I just have used the corn cob. I use the Frankfort Arsenal brass polish. I have tried the car polish and the F.A. works the best. I follow what Dillon told me, Do not polish the brass for more than 30 minutes. This leaves carbon on the inside of the shell case. This acts like a lubricant so the powder feed funnel does not get stuck in the case when you push the shell plate back down. I use the drier sheets in the bottom of the bucket that I use to sift the shell and the cob before I put it in the rotating separator, and put a sheet in the bottom of that. This removes all of the static. even in the winter when it is dry. I also wipe a drier sheet on the inside of the plastic parts when I clean things up. I think everyone procedures works the best for them.

AH HA! This is why I have had some trouble. I have seen this and there are little brass lines developing on the powder feed funnel as well. No big deal, I just use scotch bright to polish the lines off. So, if there is carbon remaining inside the case, this is not a bad thing? I thought cases had to be sparkling. Thank you for this insight.

I had been using Corn Cobb, and really did not like it. I have switched to Walnut shells 100%. It takes a little longer to get all the brass out, but I am willing to deal with it. I know there is a device to spin the brass clean of media, but did not want to spend the money for it. I am thinking of making one, but have not got around to it.

Hmmmm. I dont load on a progressive and I dont drop powder on the press. But, I was still using the Lee powder thru expander to expand my cases. No problems with 45 but with 9mm it would bind at times and shave some brass. I wonder if only tumbling for 30 minutes would have helped. I figured it was an aluminum expander button in the die that was galling (I think it is aluminum). Oh well, I use a different expander now and leave the brass in the tumbler for a few hours as I always did. No sticking with the expander I use now.

As far as media, I use pretty much what River does. About 60/40 walnut lizard litter to corn cob. I use polish and usually a cap full of mineral spirits along with a couple cut up dryer sheets. The corn con media came with the tumbler so I dont know the size. The Walnut media is the Zilla Ground Walnut I get at the local pet shop. 7 or 8 bucks for a decent sized bag that will probably go a couple years.

While I don't use waxes, the lizard bedding which is finely ground walnut shells works far better than corn cob media. I also use the drier sheets which take most all of the dirt out of the media.

Corn Cob or Walnut Shells?

Fine or Course?
______________________

Walnut Shells cleans better than Corn Cob, but Corn Cob shines better than Walnut Shells ... so, I just use a 50 / 50 mixture of both ... fixed that dilemma!

I de-prime my .45 ACP after cleaning, so it don't matter what grit size the media is.

Zilla brand Desert Blend Lizard Litter. It cleans, and shines my cases as well or better than any corn cob media I've ever used -- and no additives like car polish, rouge, mineral spirits, etc.
