Another type of cleaner has that advantage over dry media. Dry media tumblers also won’t clean primer pockets, even if you knock the primers out before tumbling. Note that tumblers will not cure case corrosion, though they may somewhat smooth a roughened corroded brass surface. 45 ACP, for example, can be harder to pry apart than two teenagers in love. 308 cases,” references we can visualize on a pragmatic level much better than, “40 cubic inches.” Generally however, the more cases we add to our tumbler, the longer it takes to clean them.īe careful when mixing different cartridge brass together in a tumbler, as the media can cause a smaller case to become tightly wedged inside a larger one―9 mm Luger and. Because cartridge cases also come in various sizes, we see tumbler capacities described as “1000 9 mm cases” or maybe “100. For tumblers, those limits are how many cases they can clean at a time. Vibratory tumblers, like people, come in various sizes and have their limits. I’m not aware of anyone who’s done a study of that―you can be the first. While shooting rouge down the bore probably doesn’t hurt it, the rouge won’t polish the bore either and it may contribute to fouling. Be aware, however, that rouge is a very fine powder that can stick to the inner walls of cases, so use it sparingly. We might instead add jeweler’s rouge, an abrasive like the media in fact, we can buy dry media with the rouge already in it. The ammonia reacts with the copper in the brass, so its polishing effect is actually chemical, not mechanical. We can add an ammonia-based liquid to increase the media’s polishing power before each tumbling session. Eventually we have to toss the worn-out media. ![]() To keep it in check we have to wipe out the tub while its contents are in the bucket. That dust is one of the drawbacks of the dry media method it’s remarkably dirty and sticks to everything. As the media particles vibrate against each other they break down into dust. Wipe the media dust from the outside of each case and we’re done.ĭry media needs occasional replacement how often depends on how hard we work it. Turn each case upside down and tap it to dump out the media that gets caught inside. ![]() Now we pour the tub contents into a sieve/sifter over a bucket to separate media from brass. When we come back, our brass looks nice and shiny. We pour dry media into the tub, toss in our dirty brass, turn the motor on and walk away for a few hours. The polishing media is ground corn cob or walnut shell. The vibratory tumbler, of necessity, is a bit loud most folks run theirs out of earshot, in the garage. Anything inside the tub―in our case, brass and dry media―vibrates along with it. The tumbler is essentially a plastic tub that sits atop an electric motor that causes it to vibrate. The vibratory tumbler is the most popular cleaning method. One way to solve this problem is to pour some teaspoons of plain paint thinner, this helps to keep the dust down and polishes the brass as well.Dry media vibratory, ultrasonic and steel pin rotary tumbler are the three basic case cleaning methods. Moreover, cleaning the dust and dry media from the brass is a pain for me since it sticks everywhere. The dry media turns into dust over multiple uses since it vibrates and hits against the brass. Reloaders out there use various types of media. If you’d ask a 100 reloaders how they clean the brass, my guess is 80% of them will tell you that they use a vibratory tumbler from manufacturers like Frankford Arsenal. The media, brass casings in the tub swirl, vibrate and collide against each other hence cleaning the dirt on the brass casings. The electric motor makes the tub vibrate and move in small circular motion. One of the oldest and most used brass cleaning methods out there.Ī vibratory tumbler setup consists of a tub and an electric motor. Top 4 Ways To Clean Brass Casings: Dry cleaning (Vibratory Tumbling): You can discard the potentially dangerous cases as with a clean brass case you can easily detect those splits and bulges. A well-cleaned brass is important for your safety too. You should know that cleaning brass isn’t just for cosmetic purposes. ![]() Why Clean Brass Before Reloading?Īlright, first things first. If you still want to know more ways to clean brass cases before reloading, keep reading. mpp-inline-1840ĭon’t let the snowflakes fool you though, for telling a staunch fan of dry tumbling that wet tumbling with SS media is better is just like telling a Hillary voter that she didn’t win.
