So what does each do and why would you choose one over the other?

Walnut media cleans faster but corncob media provides a higher polish to the brass.
I like my brass to look polished even though just clean will do.
Just my take.

I use corn cob from Graingers, size 20/40. Cleans and polishes just as good as the coarser from the reloading companies but it will not get stuck in the primer pockets or flash holes.

Forty lb. bag runs around $25.00 and will last a long time.

I mix both together.

Dry walnut cleans well, but leaves a satin finish. Followup with corncob mixed with a little Nufinish car polish to make it shine. I also believe the brand of tumbler makes a difference, my Lyman Pro 1200 Turbo is a little thing, but it runs circles around the Frankford Arsenal that I started with. I can load the Lyman completely full and it still just goes like hell. I believe it's the shape of the bowl.

I use the crushed walnut shell from Petco with the NuFinish car polish. Holy smokes, my brass seems almost "white" it's so shiny and clean, and it only takes a couple hours using my Dillon tumbler.

1st, I use the very tough Black Walnut Hull, (not English Walnut that is found in pet stores) with an additive mixed to clean the sooty brass.

step #2 isn't necessary, but I enjoy doing it.:D

2nd then the Brass goes into the soft Corn Cob media to get that extra brite shinny new look.

[ReloaderFred]

Walnut shell is hard and non-porous, so it cleans by friction. Corn cob is soft and porous, so it absorbs impurities and burnishes.

As noted, walnut will clean faster, but corn cob will shine brighter. I use both, since I've got three tumblers. One contains walnut and Berry's brass polish, one contains corn cob and Berry's brass polish and one contains just corn cob. The last one is used to polish for about half an hour to remove any traces of polish from the brass and I don't get that fine scratching that the grit from the polish can produce, no matter what brand of polish you use.

Hope this helps.

Will the corn cob or walnut also take off the sizing lube wax I use (Imperial case sizing wax). I'm thinking I'll clean them with one to get the powder fouling off, then resize my cases (.243 and .223) then run them through again to get the wax off.

[Gryffydd]

I've been using the Lyman treated walnut media in a vibratory cleaner. It gets the cases looking pretty decent, but I've noticed that even when they look nice and polished they still get my hands all black when handled. Would corn cob media be better at getting this finer residue, or do I just need to change my media more often?

[ReloaderFred]

To remove both sizing wax and polish residue, untreated corn cob will do the job. It doesn't take long at all, since I only leave mine in about 30 minutes for removing both.

I buy 1/8" ground corn cob from my local lumber yard for $15.75 for a 40 pound bag. Since the owner is also a reloader, he keeps it in stock for us.

Hope this helps.

+1 to Fred's answer..

corn cob from my local lumber yard . Reading that part of ReloaderFred's post, [[ my mind was racing ahead asking "what in the world would a lumber yard be using Corn Cob Media for???? ]] then I finished reading post.:cool::D

[ReloaderFred]

Sagetown,

They didn't used to carry it. I asked the owner if they could get it and he told his ordering girl to check into it. She found they could, so for the last 5 years or so, they've been carrying it. All it took was asking.

Hope this helps.

They use corn cob to blast log cabins before staining.
