Corn Cob Media Size Question.

riverwalker76 · March 26, 2010, 03:11 PM

Right now I'm using the Corn Cob media that came with my Thumbler's Tumbler. It's called Brass Media # 518.

I called the company today to order some more and it's $32 for 6 pounds.

Needless to say I didn't buy it, because I know I can find it cheaper elsewhere. I asked the girl what size the granules were, and all she could say was that it was a #10.

Now, I'm looking at buying corn cob media online, and I'm running across the sizes 14/20 & 16/20. What do these numbers mean? Also how can the #10 be converted to a size I could compare to these?

Thanks in advance.

Check out pet stores and such. Corn cob and walnut are both used as some sort of bedding for animals. I purchased some walnut at my local pet store a month or so ago. I also saw some corn cob at Meijer in their bulk food area in the pet department. The corn cob at meijer is a lot bigger than what the tumbling media is, but I do not see where it would be that big of a problem if it did not work as well to putting it in a bag and crushing it up more.

That is high! You can get it much cheaper at Midway I have found. Also, there is a pet lizard bedding that I hear works great. I forget what exactly the name is but it can be found at such chains like PetSmart.

I've tried using the pet bed corn cob for media, but it gets compacted in my 223 cases. After that I ended up spending an hour cleaning out my 223 cases with a welding rod to get all of the kernels out.

The walnut works great! I picked some up this afternoon @ 25 pounds for $18. I need the corn cob in a finer grain than the pet store offers.

They are ripping you off. The numbers identify the size of the media. The larger the number the smaller the particle size. You can't tell if their 10 is an apples to apples comparison with normal media. It is actually based on the sieve size the particles will pass through. For that price you can buy around 40 pounds:

just to name a few. Be CAREFUL with pet bedding. As mentioned, some are way to big for cleaning cases effectively. Don't buy unless you can see the particle size. And some have unwanted additives added for odor control. Blast media is normally cheaper, and doesn't have the additives.

That is an excellent price on the HF fine walnut at $1/lb.

Not too shabby!

jepp2 · March 26, 2010, 08:46 PM

The really nice thing about the fine walnut hull blast media from HF is that it is too small to get caught in the flash holes. I use an Lyman autoflow tumbler and even with the brass sitting up, the media flows out of the brass, while the bowl is emptying.

The mesh size relates to the number of wire openings per inch. For example, 12 mesh means there are 12 openings per inch; 20 mesh means there are 20 openings in the mesh per inch. The higher numbers mean smaller grit. These mesh sizes are standard throughout the industry. Someone's "No. 10 cob" doesn't relate to anything unless it's expressed in mesh size. Maybe 10 mesh? 1/10 inch pieces of corncob? Pretty large, almost 1/8 inch pieces. Not sure, but that size likely wouldn't get stuck in the flash hole unless it's about worn out.

$32 for 6 pounds?
When I need any media for my tumbler I go to PETS MART.
I found 25 pounds of Walnut media or 15 pounds of Corn Cob, either for around $15. This is untreated, so if you choose you add your own...

johnw63 · March 27, 2010, 06:11 PM

I just went to Midway and got something like 18 pounds of walnut media for about $16.

I didn't want to bring up this thread because it's quite old, however I did want to come on here to see if anyone needed any help with Corn Cob.

I am just offering any assistance with ordering some of it because I seen the link to our company site posted on the thread.

I might be able to help you all depending on what you need.

So I don't want to intrude, I'd just like to offer our support if needed.

Thank you for having me and I look forward to being of assistance.

Use the 14/20 grit corn cobb, I believe that's the fine media.

If you have a Granger near you. You can get the 5 gallon bucket (43 lbs) for about $26.00. That should last a long, long, long time.
