What is a common reason nickel is used in higher-end defensive ammunition?

• A. Nickel is harder than brass, improving ballistic performance
• B. Nickel has a lower susceptibility to corrosion
• C. Nickel has increased gripping when expanding in the chamber
• D. Nickel is cheaper to produce

Answer: (B)

Nickel plating on brass cases mainly provides corrosion resistance. In higher-end defensive ammo, nickel-plated brass resists oxidation longer, which helps keep the cartridge surfaces smooth and reliable in humid or harsh conditions. That reliability—especially in feeding and chambering—matters a lot in defensive use. The other ideas aren’t the primary reason: nickel doesn’t dramatically harden the case to boost ballistic performance, the nickel plating doesn’t meaningfully affect bullet expansion, and nickel plating generally adds cost rather than reducing it.
