Important Dry Tumber Features

Capacity

When looking at a new tumbler, the first thing I think about is capacity. If you only plan on doing occasional cleaning of small batches of brass, then one of the smaller, and cheaper, options is likely a good way to go for you.

On the other hand, if you plan on starting a relatively large reloading operation, say for making ammo to sell at gun shows, then you’re going to want something a little bit bigger so that you’re cleaning fewer batches.

Type of Medium

The next thing I think about is the kind of medium that the tumbler uses. Dry tumbling is a little less of a hassle and makes less mess, but it does clean the brass slightly less well. Wet tumbling leaves the brass extremely clean, but the cleanup process can be something of a hassle.

Another thing to think about here is that if you go with dry mediums, is that you’ll have to buy and dispose of that medium, whereas you can typically dispose of fluids down a kitchen or garage sink, though you might have to be careful and think about environmental considerations with some of the stronger solvents that some people sue as a wet tumbling medium.

Type of Tumbler

Between rotary and vibratory, I think that the latter is often easier to use, but the former sometimes does a better job, especially with dry mediums. Whichever type of polisher that you end up choosing, though, I think that there are polishers out there that can do a satisfactory job for you.

Reloading Basics

The tumbler generates vibration by pairing a motor with an offset weight that causes the vibratory case (or bowl) on top to shimmy at high rates. Media and brass go into the bowl, and the lip caps it off. The vibrations cause the brass and media to “tumble,” moving upward against the bowl and back down toward the center. 

The process is simple, can run on its own for hours, and does all the brass cleaning for you.

Why reload ammo anyway?

Reloading ammunition is done for several reasons. In shooting sports — such as precision rifle shooting, cowboy action, or making Major Power Factor in USPSA — loading your ammunition is sometimes the only way to produce ammo that will run in your firearm or to produce consistent rounds that shoot the same velocity each time.

Dry Tumblers - Precise loads
One benefit of reloading your own ammo? Precision. You can dial in your loads with a level of specificity store-bought ammo can't match.

In cowboy action shooting, the black powder division requires shooters only to use black powder ammunition, which can be tricky to load and is rarely sold — except by other reloaders. 

Also, in cowboy action shooting, .38 Special ammunition that shoots flawlessly through a .38 Special revolver may not feed correctly in a .38 Special lever-action rifle due to differences in the cartridge lengths. Reloading individual cartridges keeps both the pistol and rifle shooting optimally.

Lastly, competitive shooters can benefit from specific loads. Major Power Factor scoring for USPSA allows shooters to get more points for less accurate shots than shooters with ammunition only meeting Minor Power Factor loads. Shooters using hotter loads (think .40 cal and 45 ACP) are essentially rewarded for managing recoil better.

You’ve probably been taught when picking out a concealed carry handgun, for example, to pick one chambered in a commonly found caliber for which you can easily find defensive rounds. For owners of rare or collector pieces, many calibers are no longer mass-produced or — so hard to find that the only way to shoot your gun is to hand load ammo, making those casings worth their weight in gold.

Reloading saves money
Buying reloading components in bulk will reduce the per round costs signifcantly.

Why a Dry Tumbler?

Saving Money

The primary reason that people get dry tumblers in the first place is so that they can re-use brass the reload ammo.

Reloading ammunition is cheaper than buying new factory ammo. This became particularly true as a lack of availably drove ammo prices through the roof in 2020. 

As long as you stock components and pick up your own spent brass, there are savings to be had by reloading.

The reasoning behind this, for most folks, is to save money over buying newly manufactured ammunition. Doing that well, and getting the best results, depends on large amounts of well-cleaned brass.

The best way to achieve that is through the use of a tumbler: otherwise, you’ll spend a lot more time and get less good results if you decide to clean your brass by hand rather than doing it in large batches with a tumbler. 

Reducing Waste

Most people who are into shooting sports also care about preserving the environment. Sadly, shooting ranges, whether indoor or outdoor, generate a fair bit of waste. One of those waste products is brass.

Using a tumbler to recycle and re-use brass a greater number of times gives people an incentive to police their brass at a range.

Thus, the more people who start using brass tumblers, the less brass you’re likely to find littering the ground at the range and eventually making its way into the local soil. We think this is a major benefit to everyone.

Keep Shooting Hard to Find Ammunition

Specific cartridges used in rifles for PRS are not mass-produced, and even factory ammunition may not run reliably or consistently through the firearm. Usually, a shooter has to develop a specific load to optimize the control and function of the gun. 

Some calibers are hard to find even in the best of times. The problems of finding odd calibers, especially at prices that are reasonable, have been compounded in the past several years thanks to the pandemic and shortages.

One of the only ways to keep shooting calibers that are a little harder to find is to clean the brass yourself as best you possibly can to guarantee that you’ll get good performance and be able to keep shooting it for as long as possible before replacing the brass.

Reloading Supplies

The elements that you need to reload are brass, primers, bullets, and powder. Sounds easy, right? There are different primers for different cartridges, including small pistol and small pistol mag, large pistol and large pistol mag, small and large rifle, and large rifle mag. 

Some spent brass expands with the amount of pressure expended, which requires you to re-size the brass through a process such as roll sizing, for example.

Primers are one of the fundamental elements of reloading.

The Importance of Clean Brass

We can all agree that having a functioning firearm is something we want, correct? What you feed your firearm in terms of ammo plays a considerable role in whether or not your gun will run. 

That process all starts with brass that will feed into the ramp and perform reliably under stress. 

The main goal of dry tumbling is to clean your dirty brass and polish it. One pro tip is to de-prime your brass before tumbling to get a deeper clean inside the case, flash hole, and primer pockets. Untarnished, polished brass will feed more reliably and ensure your primers and bullets seat correctly.

Depending on how old the brass is, the external surface may be corroded and rough. Tumbled brass should be shiny, and you should toss out anything that is not deburred and or corroded from years ago.

Tumbling Media

Dry media vary, but one constant is walnut shells, which are great for deep cleaning brass.

While some folks speculate about roasted buckwheat and rice media, the two main options of dry media are corn cob and walnut shell. If you’re picking up your brass immediately after each range session and going home to start the tumbling process, corn cob is the better dry media option because the brass doesn’t have time to tarnish or need much polishing. 

Walnut media is a lot tougher than corn cob and is ideal for tarnished and dirty brass — you know the kind — old casings from years ago that may have been on the ground or sitting in a bucket for an extended amount of time. Walnut shell media is often the go-to choice for these old-timers.

Treated vs. Untreated Media

When shopping for media, you’ll come across labels indicating treated or untreated media. Treated media adds shine to the finish on your brass you won’t get with untreated media.

The downside to buying treated media is that you have no control over the amount of polish in the media, and too much polishing can speed corrosion in casings. 

If you choose untreated media, you can add brass polish or a little Nu Finish car polish separately and control how much or little you want to use if you really value some shiny brass.

We’ll dive into rotary tumblers below, but one type of media you can only use in these types of tumblers is stainless steel pin media. Stainless steel pins go inside the drum with the cases, like corn cob media in a dry tumbler. After removing the casings from the tumbler, you will need to sift as many pins out as possible. 

This step is the only tedious part of the process as the stainless pins have to be re-collected for each subsequent use. The main reason to use pin media is it’s the most efficient way to clean inside the case and get a much cleaner primer pocket.

Dry Tumbler or Wet Tumbler?

When you’re looking at buying a tumbler, you will also need to decide if you plan on dry or wet tumbling– the tumblers will advertise which methods and media you can use. The primary difference of how well they address and clean the inside of casings.

A wet tumbler uses more cleaning solvents and liquids that can deep clean primer pockets and the interior of the brass. 

Dry Tumbling

Dry tumbling refers to using a dry media, usually corn cob, ground walnut shells, or rice, to act as a cleaning abrasive against the brass.

This method makes for less mess, though it does create a lot of dust. Pro tip: mineral spirits and dryer sheets can help assuage the dust.

This method makes the brass clean enough to reload, but there might be just a little powder residue on the inside of the cases. Cleanup is relatively easy, and most folks use a colander and a bucket to keep things clean after the fact.

A dry tumbler is a simple setup — little more than a bowl with a lid that sits on top of an electric vibrating motor. Media, optional polish, and brass casings bounce around in the tumbler for anywhere between 4 and 6 hours for proper cleaning. The brass is then removed, sifted, and sorted (watch out for the .380s mixed in with 9mm).

Wet Tumbling

Wet tumbling, often done with either a specialist fluid or, if you’re exceptionally frugal, dish soap and water, means tossing the brass in what is effectively some kind of detergent. This method can clean the brass exceptionally well and leaves you with brass that will likely have no residue whatsoever.

The downside here is that you’ll end up with a tumbler full of wet brass and absolutely filthy water. To clean up afterwords, some people have taken to finding restaurant-size salad spinners and making use of either a washtub or a garage sink to spin the brass dry before laying it out on towels to finish drying overnight. Another option to dry brass is a cheap food dehydrator — weird but true!

The interior of a fully-loaded cartridge will always be in contact with gunpowder, with the primer and bullet both seated, sealing the cartridge from air and moisture.

The primary function of the brass is to hold the powder, allow it to burn, and direct the exploding gas — which pushes the projectile down the path of the barrel. If your preference is to have the inside of the brass perfectly clean a wet tumble life is for you!

So if wet tumbling cleans better why use a dry tumbler? Dry tumbling gets at all of your brass cleaning issues sufficiently while allowing for you to clean a lot more brass at one time, which is why dry tumblers are the go-to for most reloaders.

The Exterior Is What Matters

Dry Tumblers - Clean Brass
Dry tumblers clean the most important bits of the brass -- the exterior -- really well. They also allow you to clean more brass in a single go than wet tumblers.

When it comes to reliability and performance the external qualities of the brass are really matter — and can cause significant issues with feeding.

If the brass is splitting in any way it won’t hold up to the pressure and can lead to failure to eject. It may not discharge appropriately if the brass has a defect in the bullet seat crimping. If the primer pocket is filled with debris and can’t seat a primer correctly, this will result in a high primer or even a twisted primer that will make the cartridge too long to feed or lead to a failure to fire. 

Lastly, any external corrosion, burrs, or defects may cause the ammo to not load into a magazine correctly nor feed into the chamber.

Rotary vs. Vibratory Cleaning

Rotary Cleaning

The most common type of tumblers you’ll see for sale for home use are Rotary tumblers. These consist of a weighted bowl and a lid.

To use this kind of polisher, you add the brass and medium to the bowl, put the lid on, and the uneven weighting of the bowl will aid it in spinning the brass and medium, which tumbles everything together and ultimately cleans the brass.

They are often the most affordable kinds of tumblers, and they can be extremely effective for home uses as they’re usually fairly small and portable.

As mentioned earlier, rotary tumblers use stainless steel pins and liquid media to clean brass. A rotary tumbler is a hollow drum (think of a tiny washing machine) laid on its side. Electrically powered rollers turn the tumbler.

Watch this quick video of cleaning brass with a wet method. This tumbler maxes out at 30 pounds. The recipe he used was to add 5 pounds of stainless steel pins and 700 rounds of brass casings, fill the tumbler with water, and add a tablespoon of detergent (he uses Dawn dish detergent) a tablespoon of Lemi Shine with a cook time of 3 hours — and that’s it!

The brass is clean inside and out, the primer pockets are deeply cleaned (more so than the dry tumbling process can achieve), and the brass is also polished. These machines take less time (especially if you have less brass to clean) and are quieter than most dry tumblers on the market. 

The materials used to clean using the wet tumbling method are easy to find, cheap, and easy to dispose of. The last step to prep your brass is to dry it out (such as with a hot air dryer) and check for any leftover pins stuck in your brass. A magnet makes for a handy tool to collect all the stray pins that may be hiding.

Vibratory Cleaning

Dry Tumblers - Garage Setup
A garage setup can help keep all your supplies organized and mitigate the noisey nature of vibratory cleaning.

Other tumblers, rather than a rotary motion, make use of a vibrating motion. Vibratory tumblers consist of a base with a motor and a drum that has a locking lid. Typically, the lid is locked on with the same bolt that holds the drum to the base.

A vibratory tumbler moves up and down rapidly, tossing the medium and the brass rapidly to clean the brass. These tumblers do an excellent job, though they are often fairly loud, so we don’t recommend using these at the kitchen table on a Sunday night if everyone else is trying to have a conversation.

Vibratory tumblers like dry tumblers are available in various sizes. The capacity of these depends on the cartridges, but generally, they can clean more brass than their wet counterparts.

The vibrations of the dry tumbling process are louder than wet tumblers — which is why many reloaders create dedicated reloading stations in a garage or somewhere out of earshot. 

Media is also very dry and can act like fine powder or flour when sifting the media out of the brass. Inhaling media is not advised, especially for controlling the amount of exposure you have to lead and lead dust. 

Always sift outside, in a garage, and wear a mask and gloves. 

Dry Tumbler Pricing

  • Around $75. For around $75, you’ll be able to find a basic rotary tumbler that works fairly well and is capable of doing small batches of brass with a dry medium. These are going to be small, tabletop models more or less meant for hobby reloaders, and will serve a lot of people well. If, on the other hand, you plan on doing a large amount of brass cleaning you might want to consider a more durable, if more expensive option. 
  • $100-$150. At around the $100 mark, you can expect to find a lot of high-quality rotary tumblers, as well as some basic vibrating tumblers. For a little more than the lowest prices, you can find tumblers with larger capacities and stronger motors that can handle slightly larger batches, which can come in handy for people who do their brass cleaning in large patches.
  • $150 and Above. Over the $150 price range, you will be able to pick between several styles of tumblers, all of them with good motors and durable components, for either wet or dry tumbling that will be able to handle large capacities of brass. These are often serious pieces of equipment that will last a lifetime with a little bit of care.

Summary

The process of choosing a dry tumbler is just like anything else you’re looking to invest in when it comes to your firearms hobby. First, determine your purpose for the tumbler. Are you cleaning bulk loads of 9mm or cleaning up to 100 cases of specialty rifle cartridges? Where will you be putting this tumbler to run? In an oversized garage or on a small workbench? Knowing the size of your space will help you determine what capacity tumbler that you need.

Choosing the suitable media will be up to your level of standards of what “clean” brass looks like, as well as how much brass you’ll be cleaning for replacing used media. Always remember that a quality dry tumbler will last you a long time.
