Crushed walnut shell media

[Nature Boy]

For those that have used both cob bits and walnut shells, what are the differences in the results?

Walnut cleans extra dirty brass well, but corn cob media polishes it much better than walnut. If you're an indoor shooter you probably have no use for walnut.

Walnut cleans better/faster, but doesn't polish to as high a sheen.

Corncob polishes to a high luster, especially if you add a bit of Nu-finish, but won't take of heavy tarnish or soot.

I use the combo after matches, because the brass I bring home might not all be mine or if I'm out practicing and the previous user left a lot of brass laying on the ground...I especially like it when I follow a security companies qualification/training sessions.

I use straight corn cob to remove the lube (lanolin/alcohol) on my handgun cases

Zilla Brand lizard litter is all I have used for about 10 years now.

The fine grind is great because it very seldom gets stuck in flash holes!!

I haven't had any excessive dust in any I have purchased.

Yep! Although I only use it now to remove my lanolin/HEET lube after wet tumbling and resizing.

Is it cheaper than Harbor Freight? 25#s is $20 when you use the 20% off coupon.

You can get a 50 pound sack of 20/40 walnut at a blasting supply house for a bit over $20.

It's fine enough that it doesn't plug flash holes and it gives cases a decent polish. It is slower than coarser grades, but the extra time spent in the tumbler is worth not having to poke stuck media out of flash holes.

I just bought the 20-lb box of coarse grind walnut hulls from Harbor Freight. It works well.

I'm old school in my approach to cleaning and polishing brass. Two-step process. Walnut hulls to clean. Corn cob to polish.

Polished brass shoots better?
I've only ever used walnut, and it comes out of the hopper as clean and crisp as new.
