I disagree Avenida. I had a Lyman turbo tumbler 1200, it used to take me at least 4 hours to get 300 9mm clean. Now I have the Lyman sonic cleaner, the one that holds 1.5 liters of fluid, and I can bang off 500 9mm every 10 minutes. Once I rinse off the casings I do one of 2 things, lay them spread out on a towel to dry for a day or two, or put them on a cookie sheet and pop them in the oven for a few minutes to speed up the drying process.
Point is I clean thousands of brass now in an hour and I dont think I could go back to a tumbler.
Are you reloading/cleaning pistol or rifle? Do you like your brass really clean, inside and out, including primer pockets?
If you are reloading rifle and want really clean cases,, a rotary, wet tumbler with steel pins is the way to go.
If you are reloading pistol rounds, then a dry vibrating tumbler, with walnut media and an additive still works very well. The additive to the media makes all the difference, and you don't have to futz about drying the cases, and the additive eliminates the dust. With polishing additive, an hour or two in the Thumlers vibratory tumbler (the Industrial 18 lb capacity one), is usually more than enough. I have left it on accidentally for a day, and it actually polished off most of the nickel off plated brass !! It's the polishing additives that do that, not the walnut.
I have both, and use both, but for different purposes.
As for the ultrasonics, they remove surface dirt, but don't actually polish the brass.
What advantage is there to the stainless pin tumbling other than really pretty, shiny brass? I can load reliable, sub MOA handloads with a regular vibratory tumbler no problem.
That seems like more work to me. Once a month I throw them in the vibration unit with a cap of polish and let them go for 4-5 hours. I do it in my basement but there is no dust that comes off mine at all. I leave it on in the evening and turn it off before I go to bed. Then I separate them with the spinning cage thing-a-ma-bob (2 minutes of spinning) and then I'm done.
The best big quantity tumbler on the market is the Dillon DL2000. Holds 1500 9mm cases or 1000 38special cases. Great with 45's too.
1st hour and a bit, just tumbling. Last 20 minutes or so with a capfull of polisher and you have clean cases. Ask me how long I have had mine....
Wondering, does it produce dust ? I don't want to have my room in the basement covered with some stuff ...
This is why I'm considering sonic cleaner for my setup. But I have no experience with that, appreciate you feedback.
If you had the Dillon they would replace no charge. Mine was submerged for a week after my sump-pump quit (I was in BC), Dillon said send it back they would send a new one. I did and they did. Can't beat that with a stick.
