Finding reliable and affordable once-fired .308 Winchester (7.62x51mm NATO) M80 ball ammunition can be a challenge for reloaders. This guide explores the sourcing, characteristics, and considerations for using this specific type of once-fired brass.
Understanding Once-Fired M80 Ball Ammo
Before diving into specifics, let's clarify what "once-fired M80 ball ammo" means. M80 is the military designation for a specific type of 7.62x51mm NATO cartridge using a full metal jacket (FMJ) bullet. "Once-fired" indicates that the cartridge has been discharged only once, leaving the brass casing intact and potentially reusable for reloading. This makes it a popular choice for reloaders seeking cost-effective ammunition.
Advantages of Using Once-Fired M80 Brass
- Cost Savings: Reloading with once-fired brass is significantly cheaper than purchasing new factory ammunition. The initial investment in brass preparation tools is offset by long-term savings.
- Consistent Quality: Military-spec brass, like that from M80 ammo, generally exhibits high consistency in terms of dimensions and material, making it ideal for reliable reloading.
- Environmental Considerations: Reloading reduces waste compared to disposing of spent brass after each firing.
Sourcing Once-Fired M80 Brass
Acquiring once-fired M80 brass requires careful consideration. Several avenues exist:
- Shooting Ranges: Many shooting ranges collect spent brass and may sell it to reloaders. Contact your local ranges to inquire about availability.
- Online Retailers: Several online retailers specialize in selling once-fired brass, often sorted by caliber and condition. Be sure to carefully review seller ratings and descriptions before purchasing.
- Military Surplus Stores: These stores sometimes offer bulk quantities of once-fired brass, although availability and condition can vary considerably.
- Private Sales: Connecting with other reloaders through forums or clubs can lead to opportunities to purchase brass from private sellers.
Preparing Once-Fired M80 Brass for Reloading
Before reloading, once-fired brass requires preparation. This includes:
- Cleaning: Removing any debris, carbon, and propellant residue from the casing.
- Inspecting: Checking for any damage, such as cracks, dents, or splits, that could compromise safety during reloading.
- Sizing: Restoring the brass to its original dimensions using a sizing die.
- Trimming: Ensuring uniform case length to maintain consistent chamber pressure.
- Deburring: Removing any sharp edges from the case mouth and primer pocket.
Proper preparation is crucial for ensuring the safe and reliable reloading of once-fired brass.
Considerations When Using Once-Fired M80 Brass
- Headstamp Identification: Pay attention to the headstamp markings on the brass cases. This can help identify the manufacturer and potentially indicate the brass's quality and age.
- Condition Assessment: Thoroughly inspect each piece of brass for damage before proceeding. Discard any damaged or questionable cases.
- Safety First: Always prioritize safety when handling firearms and reloading ammunition. Follow proper reloading procedures and safety guidelines.
Conclusion
Once-fired M80 ball ammo represents a viable option for reloaders seeking cost-effective and consistent .308 Winchester ammunition. By understanding the sourcing, preparation, and considerations associated with this type of brass, reloaders can maximize their savings while ensuring safe and reliable ammunition for their shooting activities. Remember, safety and proper technique are paramount in reloading. Consult reliable reloading manuals and seek guidance from experienced reloaders if you are new to this process.
