What kind of times are you guys using what you tumble brass? im doing 4 hours and still have dirty primer pockets not completely dirty just the triangle of the primer.
thank you

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: RoosterShooter</div><div class="ubbcode-body">I'm not trying to be a naysayer, but have a few honest questions concerning SS Media Tumbling.
1) Does anyone not remember Chemistry 101 where you put a piece of copper and brass in citric acid to watch it 'dezinc'? Could this be the reason why a lot of people are ending up with Orange or Brown cases? What about being brittle after a few cleanings? Is that not a concern?
</div></div>
I'm a chemist by degree, but haven't worked in the field for some years, but I don't think there's much to worry about at these concentrations. It's probably less than a gram of citric acid in a gallon of water, plus, you need two metals with sufficient electronegativity difference for a redox reaction as you describe and stainless just ain't that active (by design) as an anode/cathode in this case. <b> Mostly the citric acid just raises the pH slightly to "soften" tap water. </b>

2) Has anyone filtered the water coming from their rotary tumbler to see how much brass is removed? A simple coffee filter will do!
</div></div>
I haven't actually filtered and weighed, but I'm sure there is a measurable amount of brass particles getting rubbed off the cases as can be seen here on a freshly uncapped gasket:
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: RoosterShooter</div><div class="ubbcode-body">
The reason I bring up these two points is because I have long been familiar with 'alternative' methods of cleaning brass. One of the rules of thumb is never use citric acid! Citric acid will cause corrosion of the brass and cause it to become brittle. This compromises the integrity of the 'SAAMI Spec' case!
</div></div>
I just got the STM kit, but I've been using citric acid in my ultrasonic for quite some time now and I have some Lapua .308 cases on their 8th reloading and show no signs of embrittlement, etc. (I anneal every 4th firing and only collet neck size). I just don't think you're going to damage brass at these concentrations.
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: RoosterShooter</div><div class="ubbcode-body">
Furthermore, SS media is used in the casting industry to debur castings. I have seen it used at a local foundry, and the castings are actually cast at .010" OVER spec to allow for changes due to the media deburring process. When the casts come out they are to spec!
Again, I'm not trying to piss on the thread. I'm just looking for some serious answers and studies. "Because it works!" isn't a valid reason for me to try it. I have some serious concerns about the ways these cases are cleaned.
My main concerns are about the elasticity of the brass after several cleanings, and the pressure sensitivity after only a few firings.
Your input is appreciated. </div></div>
I've only had the STM kit for 4 days, but I'm already having serious doubts about the process.
I know this is an old post, but my OCD just couldn't be suppressed! Adding citric acid should LOWER the pH! : ) lol I don't know how adding sodium laureth sulfate (soap) would affect things though.
Hi Everyone
Ive been trying to read up on Stainless Tumbling and found this thread.
Where is everyone getting there Stainless Media and Tumbler ?
Also is there a guide on how to do this process ?
Thanks
Allen
Got a set of dies in with a bunch of stuff that I got at a estate sale that was pretty sad. Being that I had
nothing to lose I tossed them in the SS Media, with Ivory soap and a 40 S&W case of the magic powder.
Did this effect the threads at all?
Hello. New to the site as a member, but I have lurked for quite some time.
I just received my tumbler from STM this week and have been playhing around with it. It is quite the set-up. I bought the larger 40lb model as I have about 1800 lbs of mixed brass to sort and clean.
What! Did I just read your post correctly Boss Hog?! You have 1800 lbs of brass to sort and clean!! Dude, I thought I've accumulated a lot of brass in all my years shooting cause I've never thrown any away and I'm always picking it up from my shooting buddies that don't reload.....but that is freaking insane. thats like a full time job.
John
Ok Suasponte, give me your recomendations on what type media and whatever tumbler I need to go the stainless route and who to get it from. you ? or ?.
thanks.......Patrick
Yes, the Thumlers Model "B" tumbler is my only recommendation and I will PM you Marks contact info.Ok Suasponte, give me your recomendations on what type media and whatever tumbler I need to go the stainless route and who to get it from. you ? or ?.

Make sure to keep your media rinsed well or over time the carbon will bond to the media. I usually run the media by itself
with the soap / Lemishine mixture for several hours to clean them up. Them I put them into a plastic container that I have
drilled holes into the bottom (smaller than the media diameter) and let rinse under running hot water till the water runs clear.

1800 That's correct. Had a buddy hook me up with a large load of brass. Been quite the chore, but the 40lb tumbler has made it so much easier
Gotit, thanks... I emailed Mark.Yes, the Thumlers Model "B" tumbler is my only recommendation and I will PM you Marks contact info.
Check you Pm's

My buddy and I got our media from Cabelas. He was going there anyway and had some points on his card.
I got my tumbler at an auction. Its the Thumler's Tumbler 140. It is dirty and has some rust where the paint wore through but I only paid $50 for it.
My procedure is this:
1. Media in tumbler
2. 1/3 to 1/2 gallon zip-lock bag of .223 brass
3. Fill with water to less than an inch from the top.
4. Squirt of Dawn dish soap. If you add the soap before the water it foams up.
5. Sprinkle of Lemi Shine, maybe a heaping teaspoon if I had to guess.
6. Put lid on and tumble for 4 hours.
7. Drain and refill with water 2 or 3 times to get majority of the dirty water out. Be careful to not dump brass or media out of the tumbler.
8. Dump everything into case separator.
9. Fill case separator with water.
10. Spin case separator 20-30 times to separate media and brass and also rinse brass with clean water.
11. Rinse brass under running tap to remove soap residue.
12. Spread brass out on towel and let dry for 24-48 hours. My buddy puts his on an old cookie sheet and bakes them in the oven for 30-45 minutes at 150 degrees.
suasponte,
i sent you a pm but i dunno if it went through. can you send me the info for the stainless steel media, i would appreciate it.
I have run 45's and 9mm on my Dillon 550B with the Dillon carbide dies and have not encountered this problem.
Have you double checked to make sure you die is screwed down just touching the shell plate in the ram up position?
Do not take this as a insult, just trying to rule out possible issues. Also, is your spring assist working properly.
There is no reason why your Dillon dies should not be punching out the primers regardless of cleaning with SS Media.
Unless you have a well crimped military case they should be getting the job done for you.
Is your decapp pin protruding below the bottom of the die by about 1/8 to 1/4"?
Terry
Hi Terry,
Sent you an email regarding the media supplier, not sure if you had received it or not. Please let me know, I'm looking forward to trying out stainless tumbling!
Thanks,
Rob
Rob, just sent your a PM with the contact info.
