Dirty brass leads to malfunctions, inaccurate shots, and potential damage to your firearm. Enter the world of brass tumbling, a process that can breathe new life into your spent casings, preparing them for their next adventure. And one of the most popular methods for achieving this is tumbling brass in corn cob media. But the question remains: How Long To Tumble Brass In Corn Cob for the optimal results? Let’s delve into the nuances of this essential reloading and cleaning process.
For shooters and reloaders, brass tumbling is more than just a cosmetic touch. It’s a crucial step in ensuring the reliability and longevity of your firearms and the safety of your reloading process. A clean casing allows for a consistent burn of the propellant, leading to better accuracy and minimizing the potential for problems. Think of it as preventive maintenance for your ammunition – keeping your brass clean is an investment in both your shooting experience and your firearm’s overall health.
Why bother? What are the tangible benefits of tumbling your brass? First and foremost, it removes the accumulated grime, carbon buildup, and other contaminants that accumulate after firing. These impurities can interfere with the reloading process, potentially leading to issues like inconsistent seating of bullets or improper ignition. Furthermore, clean brass looks and feels better. A well-cared-for cartridge is a source of pride for the reloader.
Beyond the aesthetic appeal, cleaning brass offers a practical advantage: it helps maintain the structural integrity of the brass. Over time, residue can corrode the brass and lead to premature wear and tear, or even cracks. Cleaning brass is a proactive measure that extends its lifespan and reduces the need for frequent replacement. This is particularly relevant for those who reload their ammunition, as reusing brass is a key element in the reloading economy.
Understanding the Basics of Brass Tumbling
While various methods exist to clean brass, including ultrasonic cleaners and specialized chemical baths, brass tumbling remains one of the most accessible, cost-effective, and user-friendly options. The process involves placing your brass inside a tumbler, a specialized machine that rotates or vibrates, along with a cleaning media. The abrasive action of the media polishes the brass and removes any lingering debris. One of the most popular and widely used media is corn cob media.
The Advantages of Corn Cob Media
Corn cob media stands out as a popular choice due to its effectiveness, affordability, and gentle cleaning action. The media is made from dried and crushed corn cobs, producing a naturally absorbent material. It offers a good balance between cleaning power and protection of the brass.
So, why is corn cob media so well-regarded? Firstly, it’s highly effective at removing carbon buildup and tarnish from the brass. The abrasive particles within the corn cob media gently scrub away dirt and residue. It also polishes the brass, restoring its shine and making it look almost brand new.
Additionally, corn cob is a relatively soft media. This means that it won’t cause excessive wear and tear on your brass cases. You can rest assured knowing that it won’t damage your casings, unlike some harsher media. This gentleness makes it an ideal choice for those who reload, as it minimizes the risk of scratching or deforming the brass, ultimately impacting its functionality and longevity.
Furthermore, corn cob media is readily available and inexpensive. You can typically find it at gun stores, reloading supply shops, and online retailers. Its accessibility combined with its affordability makes it an attractive option for both beginners and experienced reloaders.
To further enhance the cleaning process, many reloaders opt to add a polishing compound. These compounds are designed to work in conjunction with the corn cob media to enhance the polishing action and achieve a brilliant shine. Some popular compounds include brass polishes and waxes.
Factors Influencing Tumble Time
Now we arrive at the heart of the matter: Determining the appropriate How Long To Tumble Brass In Corn Cob is crucial. This is not a one-size-fits-all answer; the optimal tumbling time is influenced by several contributing factors. Understanding these variables will allow you to fine-tune your tumbling process for the best possible results.
Condition of the Brass
One of the most significant factors is the initial condition of your brass. If your brass is heavily soiled, with significant carbon buildup or tarnish, it will require a longer tumbling time than brass that is only lightly soiled. For example, brass that has been stored improperly for a long period might be heavily tarnished, requiring an extended cleaning process. Similarly, brass fired with a lot of gunpowder residue will need more tumbling.
Type and Size of Tumbler
Another important factor is the type and size of the tumbler you’re using. Tumblers come in two main types: rotary and vibratory. Rotary tumblers rotate the brass and media within a drum, while vibratory tumblers vibrate the media, causing the brass to tumble and collide with each other. Vibratory tumblers generally work more quickly and efficiently, and typically will clean brass faster. Regardless of the style, be aware of the size of the tumbler, as it impacts how much brass you can process at a time, which is useful to know if you want to tumble many casings at once.
Amount of Corn Cob Media
Furthermore, the amount of corn cob media you use is also crucial. It’s generally recommended to fill your tumbler about two-thirds to three-quarters full with corn cob media. Overfilling the tumbler can reduce the cleaning efficiency and may not allow the brass to tumble properly. Underfilling it might make the tumbling process less effective.
Additives and Polishing Compounds
The addition of polishing compounds will also impact the tumbling time. These compounds often contain abrasive particles that can speed up the cleaning and polishing process. However, using too much polishing compound can sometimes result in the brass becoming overly shiny or even coated with a residue. Experimentation with different polishing compounds can help refine your process.
Finding the Right Tumble Time: A Practical Guide
So, given all these variables, how do we determine the correct tumbling time? There are some starting points, but ultimately, it will require observation and adjustment.
General Guidelines and Starting Points
A good place to begin is to start with a shorter tumbling time, around an hour, especially if the brass is not extremely dirty. After this, check the progress of your brass. If the brass still shows significant signs of dirt or tarnish, continue the process for another half an hour. Keep a close eye on the process and make adjustments accordingly.
As a general guide, a typical range for tumbling brass in corn cob media is between one to three hours. Lightly soiled brass might require less than an hour, while heavily soiled brass might need two to three hours or even more. Remember that this is just a starting point; the best approach is to carefully observe the cleaning process as it unfolds.
The Importance of Observation
Checking the brass periodically during the process is key. Take out a few pieces of brass and inspect them under a good light source. Look for signs of progress, such as the removal of carbon buildup and the restoration of the brass’s shine. As you gain experience, you’ll develop a sense of the time needed for your brass based on its condition, your tumbler, and the media you are using.
Inspection and Refinement
After the initial tumble time, remove the brass from the tumbler and inspect it thoroughly. Evaluate the results. Is the brass clean and shiny? If it’s not quite up to your standards, put it back in the tumbler for an additional cycle. Does it meet your expectations? Perfect! If so, go ahead and move on to the next step.
The most effective way to determine the right tumbling time is to experiment and adjust. Start with a shorter time and increase it incrementally until you achieve the desired results. This process may require a bit of trial and error, but with practice, you’ll soon find the sweet spot for your specific setup.
Step-by-Step: The Tumbling Process
The cleaning of your brass is often a two-step process, and the second step is cleaning your tumbler and brass once they have been tumbled.
Brass Preparation
To begin the process of cleaning, the first step is to prepare the brass. If not already done, you should remove the spent primers before tumbling. This is best done by using a decapping tool, and removing the spent primers. Next, consider rinsing the brass in warm, soapy water to remove any loose dirt or debris. This step is particularly beneficial for heavily soiled brass, as it can accelerate the cleaning process by removing the bulk of the dirt.
Filling the Tumbler
After preparing your brass, you’ll next need to fill your tumbler. Add the appropriate amount of corn cob media, typically filling the tumbler about two-thirds to three-quarters full. If you’re using a polishing compound, add it to the media at this stage.
Next, add the brass casings. It’s generally a good idea not to overfill the tumbler, as this can hinder the tumbling action and reduce cleaning efficiency. Ensure the brass can move freely within the media.
The Tumbling Cycle
When you are ready to start the process, turn on the tumbler and set the timer. Monitor the process and keep a close eye on the brass. After the time has elapsed, you can inspect your brass.
Cleaning and Separating Brass
Once the tumbling process is complete, remove the brass from the tumbler. You can separate the brass from the media using a media separator or a strainer. The media separator is a handy tool designed specifically for this purpose, allowing you to easily filter the brass from the corn cob.
Inspection and Review
After separating the brass from the media, examine the casings. Are they clean and shiny? If they are not up to the desired standard, you may need to repeat the process. If you want to clean more brass, be sure to empty the remaining debris from the tumbler to achieve the best results for your next tumbling session.
Maintaining Your Equipment and Maximizing Results
To maintain the longevity of your media, and to ensure that you achieve the best results when you are tumbling brass, you should have a solid maintenance plan. This involves regular maintenance of your corn cob media, as well as your tumbling process.
Corn Cob Media Maintenance
The corn cob media should be replaced regularly, usually every few months, depending on the frequency of use. As the media ages, it loses its effectiveness and can become less efficient at cleaning and polishing brass. You’ll know it’s time to replace the media when the cleaning results start to diminish or when the media becomes heavily saturated with dirt and debris.
Regular sifting of the media to remove dust and debris is also essential. Dust and small particles can accumulate in the media and reduce its effectiveness. A simple screen can do the trick.
Remember to store your media properly. Store the corn cob media in an airtight container in a cool, dry place when not in use. This will help to prevent moisture from contaminating the media and will prolong its shelf life.
