Which media for 223?

I am getting ready to clean a large quantity of .222 Rem and .223 Rem brass. I was wondering if walnut media would be better than corn cob due to the small necks of the cases. Will walnut clean the inside of the cases better than the larger corn cob particles? Will walnut be less likely to get stuck inside the cases than corn cob? Thanks for any advice.

RE: Which media for 223?

I think I have my answer. I put some brand new Lyman corn cob media in my tumbler and tumbled 100 .222 Rem cases for a few minutes. When I took a case out of the tumbler, I had to tap or shake the case up to 6 times to get all the media out. This could be dangerous in that if media remains in the case, it will reduce the case volume available for powder. I will use walnut.

Both corn cob and walnut come in a variety of "grits". I buy mine in 50# bags and mix them and add a small amount of jewelers rouge for polish. So, either can be had in whatever size you like, whether small or larger. I sell mine locally for a buck a pound to gun stores and some commercial reloaders in the area. If you want to pay shipping, I can send you some finer grit that won't get stuck in the necks. jj@freelancescuba.com

i used corncob and walnut medias forever. That being said, i now use wet tumbling and stainless steel media. Thanks to Dillon for recommending the use of car wash with wax in it, and now it works smoother. SS media cleans it much better and quicker; however, SS is more expensive to start up with.

SS has worked much better for me that corn cob even with the dillon media treatment used.
