Speer Ammunition - Gold Dot .400 165 Grain Bullet

The Speer Gold Dot .400 165 Grain Bullet is engineered for self-defense with its exclusive bonding process. This process attaches the jacket to the core one atom at a time, ensuring nearly 100 percent weight retention and proper expansion. These features are critical for stopping threats effectively, as they allow the bullet to maintain its integrity and deliver consistent penetration through common barriers. This reliability is why it is trusted by law enforcement professionals.

The bonding process used in the Speer Gold Dot bullet enhances performance by virtually eliminating core/jacket separations. This is achieved by bonding the jacket to the core at the atomic level, which ensures that the bullet retains its weight and expands properly upon impact. This uniformity in construction leads to outstanding accuracy and consistent performance, making it a reliable choice for self-defense scenarios.

The Speer Gold Dot .400 165 Grain Bullet features a ballistic coefficient of .147, which affects its aerodynamic efficiency. This coefficient, combined with a sectional density of 0.147, ensures that the bullet maintains a stable trajectory and delivers effective energy transfer upon impact. These characteristics are essential for achieving consistent penetration and expansion, particularly in self-defense situations where precision and stopping power are crucial.

The Speer Gold Dot bullet is designed to perform reliably through common barriers such as clothing, glass, and car doors. Its construction ensures consistent expansion and penetration, which are vital for maintaining effectiveness in various defensive scenarios. This capability is particularly important for law enforcement and self-defense, where threats may not always be in open environments.

The sectional density of the Speer Gold Dot bullet, measured at 0.147, plays a crucial role in its penetration capabilities. Sectional density refers to the ratio of a bullet's weight to its diameter, which influences its ability to penetrate targets. A higher sectional density generally means better penetration, which is essential for ensuring that the bullet can reach vital areas of a threat, even through barriers.

Weight retention is a critical factor in the performance of the Speer Gold Dot bullet because it ensures the bullet maintains its mass upon impact. This retention is crucial for delivering the maximum energy to the target, enhancing the bullet's stopping power. The bonding process used in the Gold Dot bullets helps achieve nearly 100 percent weight retention, which is essential for effective self-defense.

The hollow point design of the Speer Gold Dot bullet is integral to its expansion capabilities. Upon impact, the hollow point allows the bullet to expand, increasing its diameter and creating a larger wound channel. This expansion is crucial for maximizing stopping power and reducing the risk of over-penetration, making it a preferred choice for self-defense.

The Speer Gold Dot bullet ensures accuracy through its uniform jacket and precise construction. The bonding process that attaches the jacket to the core helps maintain the bullet's shape during flight, reducing the likelihood of deformation. This uniformity results in consistent flight paths and reliable accuracy, which are essential for both law enforcement and personal defense applications.

The Speer Gold Dot bullet is most effective in self-defense and law enforcement scenarios where reliable stopping power is necessary. Its design allows it to perform well through various barriers and maintain consistent expansion and penetration. This makes it suitable for urban environments where threats may be partially obscured by obstacles, as well as in situations requiring precise and effective threat neutralization.

When selecting the Speer Gold Dot bullet for personal use, consider the specific self-defense needs and the firearm compatibility. Ensure that the bullet's caliber and grain weight are appropriate for your firearm. Additionally, consider the typical environments where you might need to use the ammunition, such as urban or rural settings, to ensure that the bullet's performance characteristics align with your defensive strategies.
