What is the difference between walnut and corn cleaning media other than the price?

Doe's it matter which you use or is it just personal preference?

Walnut seems to work faster. Does not polish as bright as corncob though. Corncob seems to wear out faster than walnut to me. I never did "crunch" the numbers for the econoney of one over the other. At this time, I prefer walnut.

I wonder if mixing would give the benifit of both?

When you say "wear out" I take it the corn cob get's to a point in which it doesnt clean anymore. How long does this take or is it the amount of brass you put through it?

I believe that bullet lube on cast bullets has "much" to do with this. Commercial or homegrown. Rifles cartrigdes with jacketed bullets do not do not seem to have any problem for me.

I "like" my reloads to "look" good! I would prefer that they "shoot good" and "look bad" to the reverse.

Corncob kernels get smooth and round cornered. If you have a polish in with them, they also pack up with black metal and carbon particles over time. Walnut is harder and finer. It will be the better cleaner of the two if you have no polish involved. When polish is involved, the corncob can be made to clean faster because it is more porous and holds more polish and can hold a coarser polish better. Compare green Lyman corncob and any walnut with red rouge, for example. The green corncob will clean about twice as fast when it is new.

How long it lasts is a function of both how much brass is in the tumbler and how many hours it spends vibrating in there with it. I can make a batch of corncob last a season, though it is working at half speed by the end of the year.

I agree with Unc that corncob is more porous, but I see that as being a different advantage - it should absorb more lube if you're trying to remove lube off cases after resizing.

Personally, I'm satisfied to have my cases cleaned and de-lubed, but don't care about shiny too much. Hence, I've never tried walnut. I do give it a little squirt of polish now and again, though.

Note that there are two search options at the top of the page. The one in the upper right corner is a general search tool for the Beartooth Bullet web site and its sponsored links. The one that is the fifth button in the row of buttons under the words "Real Answers To Real Questions" at the top left of the page is the one that searches these forums, and is the one you want. If you search under just "media" you will get a lot of posts that mention the news media. You want to enter "tumbler media," as gmd3006 suggested.

Also note that a list of similar threads appears automatically at the bottom of the page under the quick reply window. Just click on one to be taken directly to that thread.
