This article will delve into the world of once-fired 300 Blackout brass. We will explore its benefits, where to source it, how to prepare it for reloading, and the key aspects of reloading this popular cartridge. Our goal is to equip you with the knowledge to take full advantage of once-fired 300 Blackout brass for a truly rewarding shooting experience.
Once-fired brass refers to cartridge cases that have been fired one time previously. These cases have already been through the initial firing process, having experienced the heat and pressure of combustion. The term “once-fired” implies that the cases are being re-purposed, entering a second life cycle as components for reloaded ammunition. This reuse provides both environmental and financial benefits to the savvy shooter.
Understanding the origin of your once-fired brass is often essential. Ideally, knowing the brass’s history will inform your decisions. Did the brass come from a reputable source like a commercial shooting range? Or was it fired by a known user? Knowing how the brass was treated before you got it, is critical to determining if that brass is safe to re-load. If the brass comes from a source where you do not have detailed provenance, then thorough inspection will be very important.
Advantages of Employing Once-Fired 300 Blackout Brass
A primary reason for re-purposing previously used brass is cost effectiveness. The initial investment for reloading can be significant but with the use of once-fired brass, the expense of purchasing new, factory-loaded ammunition is offset. As a result, the cost per round for reloading 300 Blackout becomes significantly lower compared to purchasing new ammunition. This difference in cost is even more pronounced when factoring in the ability to reload the same cases multiple times, stretching your investment and the useful life of each case.
Another significant benefit is increased availability, especially during periods of high demand for ammunition. New 300 Blackout brass can sometimes be challenging to find, particularly if production is constrained or there are market disruptions. However, once-fired cases are generally more readily available through various channels, giving reloaders access to a consistent supply of components to keep shooting. This allows shooters to maintain their practice schedules and hunting activities without being entirely dependent on fluctuating market prices.
Finally, once-fired brass, when properly sourced and prepared, can be of excellent quality. While the brass has been fired once, it often exhibits wear that will still allow multiple reloading cycles. Properly prepared once-fired cases can provide consistent performance and contribute to accurate and reliable ammunition. The key is to ensure careful inspection of the brass and adhere to proper reloading procedures.
Finding Quality 300 Blackout Brass
Finding the right source is the first step to capitalizing on the advantages of once-fired 300 Blackout brass. A number of options exist, each with their own nuances.
Shooting Ranges
Local shooting ranges are frequently a valuable resource. Often, ranges allow the collection of spent brass from the firing line, either freely or for a small fee. This can be an accessible and cost-effective way to acquire brass. However, it’s essential to assess the condition of the brass and ensure that all the cases are of the correct caliber.
Online Retailers
Online retailers are also a dependable option. Numerous online vendors specialize in selling once-fired brass, typically sorted, cleaned, and sometimes even prepped for reloading. These suppliers offer a convenient way to acquire brass in larger quantities, with a certain level of assurance of quality. Be sure to compare prices and check the retailer’s reputation before making a purchase.
Gun Shows
Gun shows present another opportunity for finding once-fired 300 Blackout brass. These events provide a chance to inspect the brass in person, and often lead to interactions with experienced reloaders. While selection might be more limited than with online retailers, you may discover deals and establish relationships with other shooters.
The Shooting Community
Finally, consider asking friends or being part of your local shooting community. Other shooters may have brass they’re willing to share or sell, or may know of a good local source.
When selecting once-fired brass, thorough inspection is crucial. This includes checking for dents, cracks, bulges, and other visible imperfections that could compromise the integrity of the case. Be certain you examine the case mouth, case body, and the case head carefully. Avoid brass with any questionable features. Consider the manufacturer, as certain brands may have stronger reputations or have specific performance characteristics. Consistency in headstamps can assist in maintaining lot-to-lot uniformity in your reloads.
Preparing Once-Fired 300 Blackout Brass for Reuse
Preparing your brass properly is essential for safe and effective reloading.
Cleaning the Brass
Cleaning the brass is the initial step. This will remove any dirt, debris, and residue from the previous firing. There are several cleaning methods. A tumbler, using abrasive media, is a very common choice. Ultrasonic cleaners offer a different approach, using sound waves to clean the brass in a liquid solution. Wet tumbling, which combines a cleaning solution with small stainless steel pins, offers a very thorough cleaning. Cleaning brass not only enhances its appearance, but it also facilitates a more accurate inspection and helps the dies operate smoothly.
Inspection
Inspection follows cleaning. You’ll be looking for signs of damage, such as splits, cracks, bulges, or other flaws that could compromise the brass. Use a case gauge to confirm that the dimensions of the case are within the specifications. Always inspect the primer pockets for any deformation or residue that could affect priming.
Sizing
Sizing is a crucial step in reloading. Full-length sizing resizes the entire case, while neck sizing only resizes the neck. In 300 Blackout, full-length sizing is generally preferred, particularly if the brass is coming from different firearms. The sizing die brings the case back to the appropriate dimensions, readying it for reloading. Always use a proper lubricant, such as case lube, to prevent the brass from getting stuck.
Trimming
After sizing, trimming may be necessary. Consistent case length is important for consistent bullet seating, bullet jump to the rifling, and proper case capacity. Trim the cases to the recommended length specified in your reloading manual.
Deburring and Chamfering
Deburring and chamfering the case mouth is the next important step. Deburring removes any sharp edges or burrs from the inside and outside of the case mouth, improving bullet seating and helping the bullet seat smoothly.
Primer Pocket Preparation
Preparation of the primer pocket is also necessary. Uniforming primer pockets with a dedicated tool ensures consistent primer seating depth. If the cases were originally loaded with crimped primers (often the case with military brass), removing the crimp is necessary.
The Reloading Process for 300 Blackout
Reloading requires the following steps, but always follow the proper steps based on your experience, and always review your reloading manual.
After the brass has been prepared, the next step is priming. Place the primer of choice into the primer pocket.
Now comes the selection and the loading of powder. Consult a reliable reloading manual for specific powder recommendations and safe charge weights. Powders such as Hodgdon H110, Alliant 2400, and Reloder 7 are often used in 300 Blackout. Note that different powders may have different burn rates. When choosing your powder, you need to make sure it is appropriate for the bullet type you intend to use and the velocity you want to achieve.
Powder charge weights vary based on the specific powder, bullet weight, and desired velocity. Use a powder scale to accurately measure your powder charges. Begin with minimum loads as listed in a reliable reloading manual, then gradually increase the charge weight, carefully observing for signs of excessive pressure such as flattened primers or difficult bolt extraction.
Bullet selection and seating are the next steps. Choose a bullet weight and type that is suitable for the intended purpose. Generally, heavier bullets are used for subsonic loads, while lighter bullets perform well at supersonic speeds. Seat the bullet to the correct depth specified in your reloading manual, ensuring a consistent overall cartridge length.
Crimping, the final step, may be necessary depending on the bullet type, profile, and your overall desired consistency. A light crimp can help ensure the bullet remains securely seated, especially if you are using a cannelured bullet.
Safety and Best Practices to Employ When Reloading
Always, always prioritize safety. Always wear safety glasses and gloves. Always work in a well-ventilated area to avoid inhaling fumes. Always consult at least one, and preferably two, reputable reloading manuals for load data. Always start with the minimum recommended powder charges and incrementally increase the charge, carefully looking for any signs of excessive pressure. Always inspect every loaded round. Always label your ammunition clearly, including the load details. Always store your reloading components and finished ammunition safely, away from children and unauthorized individuals.
Addressing Common Issues
Reloading can, from time to time, involve troubleshooting.
Stuck cases are a possibility. Apply more case lube to prevent this issue. Light loads, leading to insufficient propellant, can cause unreliable cycling or failure to fire. Ensure proper powder charging. Primer issues such as failures to seat can be resolved by more careful primer pocket preparation or by switching primer brands. Incorrect case capacities lead to under- or over-pressurization of loads. Bullet seating depths that are too long can increase pressure, while those that are too short can lead to inconsistent groupings.
By understanding these potential issues and their solutions, you can improve your reloading results.
Case Life and Signs of Failure
Case life is finite. Factors that influence the number of times a case can be reloaded include the type of brass, the pressure of the loads, and the care taken during the reloading process. Brass will eventually fail.
Signs of brass failure include split necks, loose primer pockets, and head separation. Regularly inspect your cases, and discard any that exhibit any of these warning signs.
Conclusion
Utilizing once-fired 300 Blackout brass is an excellent way to maximize your performance. The cost savings, easy availability, and potential for customized loads make this a smart choice for any dedicated shooter. With proper preparation and adherence to safe reloading practices, reloading with once-fired brass can become a truly rewarding and educational hobby. Remember to always consult reliable reloading manuals and prioritize safety above all else.
Remember that the most reliable resource for any of these steps is a reputable reloading manual. Use the data in your manual for the bullet and powder combination you intend to use. Safety always comes first.
