Finding high-quality, once-fired 300 Remington Ultra Magnum (RUM) brass is crucial for reloaders seeking accuracy and consistency. This guide explores everything you need to know about sourcing, inspecting, and preparing this popular, yet sometimes elusive, brass.
Understanding the Demand for 300 RUM Brass
The 300 RUM cartridge is known for its impressive power and long-range capabilities, making it a favorite among long-range shooters and hunters. This popularity translates to a high demand for brass, particularly once-fired cases which offer superior quality compared to range pickup brass. Finding reliable sources for this specific caliber can sometimes be challenging.
Sourcing Once-Fired 300 RUM Brass: Where to Look
Several avenues exist for obtaining high-quality, once-fired 300 RUM brass:
1. Online Retailers:
Many online retailers specialize in selling reloading components, including once-fired brass. Look for reputable dealers with positive customer reviews and clear descriptions of their brass condition. Pay close attention to descriptions indicating the brass is truly once-fired and free from significant damage.
2. Forums and Online Communities:
Engaging with online forums and communities dedicated to reloading and shooting can connect you with individuals selling their once-fired brass. This often offers a more personal and potentially cost-effective option. Be sure to establish trust and verify the seller's reputation before making a purchase.
3. Gun Clubs and Shooting Ranges:
While less reliable for consistently obtaining once-fired 300 RUM brass, checking with local gun clubs and shooting ranges can occasionally yield positive results. Be prepared to sort through a mixed selection of brass, and remember to ask permission before collecting any brass.
4. Auctions and Classifieds:
Online auction sites and classified advertisements can offer opportunities to find 300 RUM brass. However, always thoroughly inspect listings and be cautious of potential scams. Verify the seller's legitimacy and carefully review photos before bidding or making a purchase.
Inspecting Your 300 RUM Brass: Quality Control is Key
Upon receiving your once-fired brass, carefully inspect each case for the following:
- Dents and Cracks: Look for any significant dents or cracks that could compromise the structural integrity of the case.
- Case Head Separation: Examine the case head for any signs of separation, a critical defect requiring discarding the case.
- Primer Pockets: Ensure the primer pockets are in good condition and not excessively expanded.
- Neck Condition: Check the neck for any signs of excessive wear or damage.
Preparing Your 300 RUM Brass for Reloading
Once you've inspected your brass and discarded any damaged cases, you can begin the preparation process:
- Cleaning: Thoroughly clean your brass to remove any residual powder, primer residue, and debris.
- Deburring: Carefully deburr the case mouths and flash holes to prevent damage to your sizing die and ensure proper seating of the bullet.
- Sizing: Size your brass to the correct dimensions using a suitable sizing die.
- Trimming: Trim the cases to the proper length to maintain consistency and prevent problems during reloading.
By following these guidelines, you can successfully source, inspect, and prepare once-fired 300 RUM brass for consistent and accurate reloading. Remember, using high-quality brass is an investment in the precision and safety of your reloading efforts.
