Thought my tumbler was due some new media and bought some Lyman tufnut. It gets the brass very clean but leaves a hellish red dust residue in and over the case. Has anybody else found this? I have been heavily cleaning them after, especially the inside of the necks, should i go to this trouble?

Cheers Rich.K
 
Best way to reduce/eleminate dusty residue is to tear paper towels into 6 or 8 2"x2" pieces and put it in the tumbler with the brass..every time you use it..replace the paper towel pieces with clean ones each time..It will eventually absorb all of the dust.and your hulls will come out dust free..Yes clean the inside necks with a brush after tumbling...
 
That "red dust" is jeweler's rouge...........

did you apply it or was it already on the media???? If you are using a vibratory tumbler, media w/this agent is not the proper media to be used as the rouge, I was always told, will "clump up" on the bottom of the bowl. It was always, in the ol' days, said that THAT treated media was for rotary tumblers only. Drop in about 2-3 teaspoons(got any??) of ascorbic acid in there, too, it helps prevent stress corrosion cracking while you're tumblin' away.;)
 
I use that stuff too,and have the same experience.

First I use corncob (green) for 3 hours,then tuffnut (red) for 3 hours.Reason is corncob takes up the dirt.Now and then I put some extra Dillon polish in it.

The cases are red as you state.To remove it I use untreated finely crushed nutshells (no brand,get it from my local gun shop) and turn them 15 minutes.They buff the cases and remove the red dust and excessive polish

After that you've got to wear shades:DOnly minus is that you have to change media a few times,but with a Dillon separator that's easy.
 
I havent added anything to the media, just staright out of the box. Thanks for the ideas I will give them a go, the paper towel is an easy winner if it works in this case :)
 
The jeweler's rouge on the exterior of the cases will not do nice things to your dies, and any of it left on the inside of the cases will be blown down the bore.

I use ground corn cob with a little water which cleans things up pretty nicely without any abrasive residue behind. Works well on filthy handgun cases.
 
In addition to paper towels in the mix, I have heard that used Bounce sheets work very well, too. You can get untreated crushed nutshell media at pet supply stores -- they sell it as bedding for rodents, I think. I get the red off by taking a large old bath towel, spreading it out, dumping the cases in the center, folding the towel into thirds lengthwise, then grabbing the ends and lifting it up and down and tumbling them from one end of the towel to the other. All the red comes off on the towel.
