My guess (just a guess) is that the walnut bird litter contained some kind of additive that didn't agree with your polishing compound. It could be that your .223 brass is made of a slightly different alloy than your 45 brass and perhaps the added metallic element in your brass is reacting with the mixture of chemicals. Look at your bag of walnut and see if they listed any additivies (they probably won't list it even if they do add it).
I would go to your local gun shop and get a small bag of walnut that is designed for reloading and then add your brass polish. I usually have two sets of media, one that is really loaded up with brass polish, like half a bottle. This batch of media works great on that range brass that has been sitting outside for years and has gotten really nasty and black. Then I follow up with a load of walnut with much less brass polish, this puts a high gloss shine on the brass. |

cgaengineer, For the worst of brass I use vinegar, I use vinegar once, after that I do not let it go back to an abused looking state, I never clean brass with vinegar for more than 15 minutes, we are talking about the straight stuff, 4%, the reason I do not make it a habit (using vinegar) is because the acid attacks the zinc, when this happens the case turn pink, if someone chooses to slow the process, they can use half water/half vinegar, I also use the vinegar to remove rust from old tools. I add nothing to the tumbler media, I make a tool for cleaning/polishing small numbers (20 cases) as when testing a rifles with 20 rounds, I can polish 20 cases before I can tumble them.
On occasions I have had the opportunity to acquire cases 'cheap' because of the amount of time someone thought was required to cases clean turned into days instead of a few hours, vinegar cuts two days off of cleaning over tumbling, on tools, no wire brush, scraping or grinding, vinegar does all of the work.

like i said earlier i have had zero problems with adding flitz to my walnut media. it cleans great and with the flitz it will polish like you had corn cob.
I also keep the older media in a seperate container and use it to clean and the new stuff is for polishing after I get done resizing. JOE

Your brass is finished for if you soaked them in vinegar. Vinegar is acetic acid and acetic acid will make the brass extremely brittle. The tell tale sign is the reddish color that you indicated. Take that brass to the scrap yard and get a few pennies for them and start over with virgin media - no additives. Plain Jane media will clean up cases just fine.

cheap enough
I once again recommend corn cob media intended for case cleaning (and Dillon Rapid Polish, although I'm getting excellent results with Franklin Arsenal's polish, but I haven't had fifteen years of storage testing performed yet).

I only load 30 cal. or straight wall pistol cases so media size is not an issue for me,I use Walmart corn cob bedding and three caps fulls of Nu Finish,about three hours average tumble time is all it takes. It even makes old 54r surplus brass cases look new as well as the old pulled bullets. Total cost for a years supply of media and polish about $15.
