Best 308 Brass for Reloading Comparison Table

How to Choose the Best 308 Brass for Reloading

The best 308 brass for reloading should be durable, uniform in size, and free from defects to ensure consistent performance and safe shooting. Choosing quality brass reduces the risk of malfunctions and saves money by allowing more reloads without frequent replacements.

Material Quality

Brass with uniform composition lasts longer and reloads better. Lower purity brass often contains more impurities that cause corrosion or brittleness.

Over time, corroded brass can lead to feeding problems and uneven pressures during firing. The best brass usually has a high copper content around 70% with zinc making up the rest, giving it good strength and resistance to tarnishing.

Thickness consistency matters a lot for performance. Brass cases with uneven walls wear out faster and can cause pressure spikes or misfires. Good brass will have consistent case wall thickness, especially near the neck and head, maintaining stable internal pressures across reloads.

This ensures you can reuse your cases multiple times safely without worrying about sudden case failures or accuracy issues.

Case Dimensions and Consistency

Precise case dimensions prevent jams and improve shooting consistency. Variations in neck diameter may cause bullet seating problems, while inconsistent head sizes can result in improper chambering or difficult extraction.

Cases that have minimal size variation feed smoothly through magazines and rifles without bulging or sticking.

Case length and wall thickness also impact pressure control. Too short or too thin cases risk rupturing under firing pressure.

Good brass keeps length within tight tolerances, usually within a few thousandths of an inch, and maintains consistent wall thickness for uniform expansion during firing. This reduces the likelihood of dangerous pressure spikes and improves shot-to-shot consistency.

Primer Pocket and Flash Hole Condition

The primer pocket’s tight fit is critical for reliable ignition. Loose pockets cause primers to fall out or shift, which can produce misfires.

Clean, well-sized pockets hold primers securely and enable easy depriming during case preparation. Flash holes need to be clear and properly centered to allow consistent flame travel and powder ignition.

A case showing irregular or damaged primer pockets or flash holes should be discarded. Signs of previous use like flattened pocket edges, uneven flash holes, or partial obstructions affect ignition reliability and the powder burn rate. Well-maintained brass has smooth, uniform pockets and clean flash holes that contribute to consistent firing results.

Load Capacity and Pressure Handling

Good cases handle high pressures without deforming or rupturing, which is especially important for loads pushing bullet velocities upward of 2800 fps. Brass designed for high-pressure loads has thicker case walls and stronger alloys.

This allows you to safely experiment with different powder charges or heavier bullets without risking an unsafe pressure spike.

Internal volume matters for adjusting charges too. Cases with sufficient capacity let you load a wider range of powders and bullet weights while keeping pressures within recommended limits. Having brass that accommodates your favorite bullets, whether they are 150-grain or 180-grain, means more flexibility in your reloads without equipment damage or accuracy loss.

Ease of Cleaning and Preparation

Dirty cases slow down the reloading process. Brass that easily sheds carbon buildup, dirt, and oxidation reduces the time needed for cleaning between reload cycles.

Brass compatible with tumblers or ultrasonic cleaners makes maintenance practical and efficient.

Some brass resists tarnishing longer, making prep cleaning less frequent. Cases that clean quickly with standard media like walnut shells or corncob reduce the effort involved. Spending less time scrubbing and more time shooting matters after multiple reloads, as rough or sticky cases often need re-polishing or resizing to feed reliably.

Proper Cleaning and Maintenance Techniques for .308 Brass

Cleaning .308 brass before reloading is crucial for consistent performance and reliable chambering. Most reloaders start with a basic wet tumbling process, using a mix of water, a small amount of detergent, and stainless steel pins to remove carbon and primer residue. This method cleans efficiently but requires thorough drying afterward to prevent corrosion.

Some prefer dry tumbling with media like crushed walnut shells, which is gentler on the brass and doesn’t require drying. However, it may not remove heavier residues as effectively.

Regardless of the method, run your brass through a sizing die after cleaning to ensure proper neck tension and overall case dimensions. Always inspect the brass for cracks or dents that might affect safety and accuracy before resizing.

• Wet tumbling: effective, requires drying
• Dry tumbling: gentle, less messy
• Sizing after cleaning: essential for uniformity
• Visual inspection: catches potential issues early

Comparing New, Once-Fired, and Lapua Brass: Performance and Longevity

New .308 brass tends to be perfectly uniform and free of deformities, offering the most consistent starting point for precision shooting. Once-fired brass straight from reputable sources generally performs well but can show minor case stretching and primer pocket wear, which reloaders usually address by trimming and reaming.

Lapua brass stands out in the reloading community for its durability and dimensional consistency. Many reloaders report that Lapua cases maintain shape and resist case head expansion better over multiple reloads, reducing the need for extensive resizing. This quality often translates into longer brass life and more consistent chamber pressures during shooting.

• New brass: best initial uniformity
• Once-fired: more affordable, requires careful prep
• Lapua brass: high durability and reload longevity
• Brass choice impacts cleaning and sizing routines

What Is the Safest Way to Resize 308 Brass Cases?

Use a good quality full-length resizing die and apply a lubricant if the brass is not annealed. Slowly resize the brass to avoid excessive force, which can cause case neck or shoulder damage. Check the resized brass for signs of splitting before continuing.

Can 308 Brass Be Used with Different Powder Types Safely?

308 brass can be safely used with different powder types, but always follow load data from reputable sources. Different powders burn differently, so start at the minimum recommended loads and watch for pressure signs during firing. Consistency is key for safety.

How Many Times Can 308 Brass Be Reused Before Discarding?

308 brass can typically be reused 5 to 7 times, depending on the load and care taken during resizing and cleaning. Inspect each case for signs of wear like cracks, splits, or weakened necks, and discard any cases showing damage before they become dangerous.

What Common Problems Should I Watch for When Reloading 308 Brass?

Watch for signs like cracked necks, split primers, or overexpanded cases. Also, avoid using brass with significant fire forming or signs of case head separation. Tracking the number of reloads per case and inspecting carefully before each reload improves safety.

Conclusion

Choosing the best .308 brass for reloading really comes down to consistency, durability, and price. You want brass that holds up through multiple reloads without cracking and has uniform dimensions to maintain accuracy.
