This morning I just finished my first, experimental batch of brass with this stuff. (150 rounds of mixed headstamp range pickup .223). The stuff was pretty grungy. I started by running it through my Ultrasonic Cleaner with a mixture of hot water and some dish washing soap to get the grit off so I wouldn't scratch my resizing die. I then full length resized and deprimed it with a RCBS Small Base Resizing Die. After that I ran all of them through my Dillon 600 Super Swage to remove any crimp on the primer pockets. Not all were military, but it was easier to run them all through rather than waste time separating them. Next I ran all of them through my Giraud Power Case Trimmer. It does a really nice job of trimming them to length, plus it puts a nice chamfer on both the inside, and breaks the burr on the outside of the case at the same time. It's amazing how much brass it removes from just 150 cases trimming them to minimum overall length.
After that I tossed them into the Thumlers Tumbler with 5 pounds of the Stainless Steel Media, a tablespoon of "Dawn" dish washing liquid, and 1/8th teaspoon of "Lemi-Shine". I then filled the tumbler up to within an inch of the top with luke warm water. I then installed the lid, tossed it on the tumbler, and plugged it in at 1:30 PM yesterday afternoon. I decided to let it run overnight because the brass was really dull and dirty, and also because my Thumlers Tumbler has a 1,500 RPM motor. The newer units have the 3,000 RPM motor, and give faster results. I didn't want to rush it, and I wanted the brass to be as clean as possible.
I got up at 3:30 AM this morning because I've got an early dentist appointment, (6:30 AM), and I wanted to get the brass out of the tumbler, rinsed, and drying before I left. THE BRASS CAME OUT BEAUTIFUL! Without any exaggeration the stuff is cleaner and shinier than new brass. The primer pockets and flash holes were absolutely spotless, and the cases shined inside and out. I'll try to get some pictures up later this afternoon when they're finished drying.
The only issue I had was partly my fault. The video on this stuff shows them using a Frankford Arsenal Media Separator. Cabela's has them and they're not that expensive. I was going to go pick one up yesterday, but I was too lazy. Melanie and I had a few glasses of wine each, and I wasn't going anywhere. The media separator allows you to float the Stainless Steel Media out of the cases by tumbling them partially submerged in the provided bucket you get with the separator. This is important otherwise the surface tension of the water will cause the media to stick to the sides of the case. I only had 150 cases so I just ran them under a light stream of tap water and it worked fine. I'm going to get the media separator because it would be a PITA to do that with a large batch of several hundred cases. This is the way to go if you want really nice clean brass. I'm still in the experimental stage with this stuff. Next I want to find a method and tumbler for large amounts. It all sounds more involved than it really is. The actual cleaning of the brass itself is an all but effortless process. Prepping the brass is always a pain, but you have to do it if you want good reloads. Remember, this was range pick up brass. It was filthy, dirty, and totally grungy inside and out. Even the inside of the case rims shine like new brass, and they were completely black! Bill T.
