Graf Corn Cob Untreated Tumbler Media 9 Pound

My results with Graf's case cleaning products have been very positive. I use this corn cob media with a little Graf's polish in an old Lyman vibratory machine, and in 60-90 minutes, all but the most tarnished cases are shiny and ready to work with.

When you are using this media, put a few drops of water in it to stop the dust, this also stops it from clogging up the primer pocket!!!!!!!!!!!!!!

Good quality great price!

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

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

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.

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!!!
