I have used one of these tumblers since the 80’s. I have used it with dry and wet media. after 30 years, I have cleaned tens of thousands of rounds with it. I keep expecting it to spring a leak, burn the motor up, or otherwise fail. However, it just keeps on tumbling. Incredible…

Caution when cleaning tight neck chambering brass. Case mouths will peen over a bit. Check a reloaded round to be sure it is the proper diameter to chamber in your rifle. It will require sizing and chamfering inside and out. I loaded up 50 rounds as they came out of the tumbler, went to the range and couldn’t shoot one round. 6PPC Benchrest. They wouldn’t chamber.

People still buy the Thumler? Frankford Arsenal’s Rotary Tumbler has 3x the capacity and is cheaper even after they include 5lbs of SS media with the tumbler. FA’s Rotary Tumbler is superior in every category: Price, Reliability, Ease of Use, Capacity, and Performance. They have them on Amazon for $164 with free shipping: http://www.amazon.com/Frankford-Arsenal-909544-Rotary-Tumbler/dp/B00HTN4R6O/ref=sr_1_2?ie=UTF8&qid=1434720630&sr=8-2&keywords=rotary+tumbler

I wonder, what are views of 6ppc and 30 br shooters whether having a “squeaky clean” brass is helpful in benchrest precision/accuracy shooting competitions.

Also be aware that if you’re shooting tight neck chambers or turned cases, that the banging motion of the steel/cases will peen the necks. You will need to trim and debur in order to have them fit the chamber again, essentialy ruining your brass if you do this every time.

No problems for standard factory chambers and out-of-the-box ammo/cases, but beware to precision shooters.

While this article centers around Sinclair’s product offerings, which includes the Thumbler brand, it does mention STM. They sell the Extreme Tumblers Rebel 17 model, which is superior to the Thumler’s Tumbler Model B. I’ve owned both, and prefer my Rebel 17 to the model B.

My Dad got one of these kits and we both use it now to clean our brass. Simple and very effective. We use the cleaners listed in the instructions.

Yep! It cleans up even nasty-looking brass! Just one thing, though: if you spent a lot of time beveling and chamfering your case necks you’re going to want to have a look at them after tumbling. I found that I needed to do some touch-ups.

There are a few tools I can’t do without and this tumbler is one of them. What a nicely-made piece it is.
