Graf Corn Cob Untreated Tumbler Media 8 Pound
For use with vibratory case tumblers. Corn media is more porous than walnut and therefore absorbs brass polish slightly better than walnut. As a result, corn is an excellent polishing media. For best results, treat media with Graf Hi-Luster Brass Polish (sold separately).
Sold by volume, weight is approximate.

Graf’s Corn Cob Media

This material does a good job when left in the tumbler 3-4 hrs. It’s pretty dusty and it does clog in the primer flash holes. Best to use before depriming by the you must clean the primer pocket.

Been using it for years to clean my brass. Best price I've found in a commercial company.

I have had the best luck by running the dirty casings thru the media prior to resizing the casings, This way I don't have to worry about media getting lodged in the flash holes.

Works well and is inexpensive too. Have run about 3 lbs through a few cleanings with good results.

Great for Initial Cleaning

Been buying Graf's corn cob media for years. Best price online for media. My take is that corn cob is corn cob. I use corn cob for for my initial brass cleaning with primer still in BEFORE I resize. Then walnut media for a polish, then resize. After resizing (especially for rifle brass to get rid of the resizing lube) I polish again with walnut media. Lengthens the brass prep process but gets the brass looking good. The walnut media is small enough that it does not get stuck in the primer pocket. Ready to load.

I have been using Graf’s corn cob media for over 10 years and love it. Yes, it can plug a primer pocket and sooner or later it will. The solution I found is a dentist pick which works great for removing the media from the flash hole. I have also used, over the years, every media on the market and Graf’s media is far cleaner than anyone else’s.

tumble your brass before you decap your cases! after you clean the pockets with a pocket brush. I have found that this is the fastest and easiest way to clean my brass, but if you like cleaning the flash holes then decap them first!
Graf Corn Cob Untreated Media

I spent 60 min. cleaning out the primer flash holes on a batch of two hundred .223 Rem. cases after using this media for the first time. It cleaned the brass well enough, but the mesh size is not well suited for small rifle primer pockets, i.e. it sticks in the flash holes and blocks them. I would not have purchased this product if I had known this in advance. It might work O.K. for cases with large rifle and pistol primers, I will have to try it out and see. Not Recomended!!!
