Just a little more aggressive

[sealer]

Is there anything just a little more aggressive than walnut hulls for tumbling brass in a dry tumbler? I know there is ceramic and other things, but I'm just wanting just a little more.
TIA, Dennis

Ya might try putting some sort of automotive polish or rubbing compound in with the walnut hulls,
or more of it, and letting it run longer.
I do corn cob media with auto rubbing compound and let it run over night.
The brass comes out looking new.
Over time, the rubbing compound or polish also becomes sort of dull and needs to be 'refreshed'.

A problem with getting too aggressive is losing the 'shine' and the brass being dull looking from the scratches of
something too coarse.

I ran some 270 win brass in walnut shells overnight. Half nickel and half brass went in, just brass came out. This media may have been treated with jewelers rouge, I don't remember for sure.

After scratching a .270 sizer die with Nickel cases, I discard plated rifle brass now, or sell it.
I've seen & have scrounged a lot of .45ACP and .38Spec. where the Nickel plating was polished off.

I use the iosso brass polish in corn cob media. I start the tumbler add the iosso 2 ounces of alcohol and let run for 5-10 mins then add the brass. cleans really fast and a great shine. A little new finish polish added will prolong the shine

Are you using plain walnut shell or the Treated Walnut Shell ?
The treated media has red brass polishing compound mixed into it giving it a Red color ... the treated media is designed for polishing brass cases very bright and shiney ... an it works faster .
Beats any liquid car wax you can add ... Seven Ways to Sunday !

Try a smidgen of Dillon case polish. Along with a splash of mineral spirits. I don't usually use the Dillon polish, but when I do it makes a big difference.

Add some of each to the walnut, run the tumbler for several minutes to distribute it. Then add the brass.

Yep, mix up some NuFinish and OMS 40/60 and dribble it into the walnut media with the tumbler running.
The liquid mix will "hydrate" the walnut and eliminate any dust in it.
Once the walnut has a even color, add the cases.
That's what I did before switching to wet/pins.

I`m with 45_Colt.
I have been cleaning/polishing brass with walnut media for a number of years.
I have used many different brass polishing additives with the walnut.
Dillons is definitely the best that I have used.

I also use iosso in corn cob media for start, then filter out media, dump cases and finish in corn cob media that has a slight bit of Nu finish car wax. If brass was shot in autoloader i start with wet cleaning in dawn and lemishine, then dry before dry tumbling. The dry tumbling makes sizing on a 550b with carbide dies a bit easier. with corn cob media you need to insure decap pin goes thru flash hole to clean up any media stuck in it. If wet cleaning, i always decap first. the wet cleans the sand and dirt so i can go sometimes 5 yrs before i need to change corn cob media.

+1 on the iosso polish.
