This specific ammunition represents a premium, bonded jacketed hollow-point cartridge designed for personal defense and law enforcement applications in rifles chambered for the 5.56x45mm NATO cartridge. The “bonded” construction refers to a process that fuses the jacket to the lead core, ensuring consistent expansion and weight retention upon impact for reliable terminal performance. This particular loading utilizes a 64-grain projectile, a weight often favored for balancing velocity and energy transfer. The manufacturer, Speer, is well-regarded for producing high-quality ammunition.
The bonded design seeks to minimize fragmentation and maximize penetration depth, particularly important for self-defense situations. Accurate bullet placement and predictable terminal ballistics are crucial for minimizing collateral damage and maximizing effectiveness. This type of ammunition reflects advancements in bullet technology, aimed at improving stopping power while mitigating overpenetration. The choice of a 64-grain projectile allows for a flatter trajectory and higher velocity compared to heavier bullets, contributing to accuracy and energy retention at longer ranges.
Understanding the design and purpose of this specific ammunition allows for informed decisions regarding its selection and application. Subsequent discussion will cover aspects such as ballistic performance, suitable firearm platforms, and comparative analysis with alternative ammunition choices.
1. Bonded Construction
Bonded construction is a critical feature of the Speer Gold Dot 5.56 64 gr cartridge, directly influencing its terminal performance and suitability for specific applications. This manufacturing process permanently fuses the copper jacket to the lead core, enhancing projectile integrity upon impact.
-
Enhanced Weight Retention:
Unlike conventional jacketed bullets that may shed their jackets upon impact, bonded construction ensures the projectile retains nearly all its mass. This characteristic translates to greater penetration depth and more consistent energy transfer to the target, crucial for reliable stopping power.
-
Controlled Expansion:
While designed to expand upon impact, bonded construction helps regulate the expansion process. This prevents excessive fragmentation, which can reduce penetration and limit the transfer of energy. The controlled expansion of a bonded projectile maximizes the wound cavity while maintaining sufficient penetration.
-
Improved Performance in Barrier Penetration:
Bonded bullets demonstrate superior performance when encountering intermediate barriers like glass or light cover. The bonded jacket prevents separation and deformation, ensuring the projectile maintains its integrity and trajectory, enhancing its effectiveness in complex environments.
-
Suitability for Self-Defense and Law Enforcement:
The combination of controlled expansion, weight retention, and barrier penetration capability makes bonded ammunition, like the Speer Gold Dot, highly suitable for law enforcement and self-defense scenarios where reliable performance under varying conditions is essential.
In the context of the Speer Gold Dot 5.56 64 gr, bonded construction is a key differentiator contributing to its effectiveness as a personal defense and law enforcement round. This design feature enhances its terminal performance, particularly in situations demanding reliable expansion, consistent penetration, and effective energy transfer. The resulting predictable behavior enhances user confidence and increases the probability of successful outcomes in critical situations.
2. Hollow-Point Design
The hollow-point design is a crucial element of the Speer Gold Dot 5.56 64 gr round, directly influencing its terminal ballistics and intended purpose. This design feature distinguishes it from full metal jacket projectiles, impacting its energy transfer and wound cavity characteristics. The following points explore the key facets of hollow-point design in this specific ammunition.
-
Controlled Expansion:
The hollow cavity at the nose of the projectile initiates expansion upon impact with a target. This expansion increases the projectile’s frontal surface area, transferring more energy and creating a larger wound cavity. In the Speer Gold Dot, this expansion is further regulated by the bonded construction, enhancing its effectiveness while mitigating over-expansion and fragmentation.
-
Enhanced Energy Transfer:
The increased surface area resulting from expansion enhances energy transfer to the target compared to non-expanding projectiles. This rapid energy transfer contributes to effective stopping power, a critical consideration for self-defense and law enforcement applications.
-
Reduced Penetration Depth:
Compared to full metal jacket bullets, hollow-points generally exhibit reduced penetration depth due to the energy dispersion associated with expansion. This can be advantageous in certain scenarios by minimizing the risk of overpenetration and collateral damage.
-
Terminal Ballistic Performance:
The terminal ballistics of a hollow-point projectile are influenced by factors such as velocity, target density, and projectile construction. The Speer Gold Dot, with its bonded construction and specific 64-grain weight, is designed to optimize these factors for reliable and consistent performance in its intended applications.
The hollow-point design of the Speer Gold Dot 5.56 64 gr, combined with its bonded construction, contributes to its effectiveness as a specialized round for personal defense and law enforcement.

This translates to improved accuracy and reduced bullet drop at longer ranges, beneficial in scenarios requiring precise shot placement. The higher velocity also contributes to increased energy at impact.
-
Energy Transfer and Terminal Ballistics:
While lighter than some alternatives, the 64-grain projectile in the Speer Gold Dot is designed to expand reliably upon impact due to its hollow-point design and bonded construction. This controlled expansion facilitates effective energy transfer to the target, contributing to desirable terminal ballistic performance for self-defense and law enforcement applications.
-
Recoil and Controllability:
Generally, lighter projectiles produce less recoil than heavier ones. The 64-grain projectile contributes to manageable recoil impulse, allowing for faster follow-up shots and improved controllability, particularly beneficial in dynamic shooting situations. This characteristic enhances overall effectiveness and user comfort.
-
Barrel Length Considerations:
While 64-grain projectiles perform well in a variety of barrel lengths, they are often favored in shorter barrels. In longer barrels, lighter projectiles may not achieve optimal velocity and may exhibit less stable flight characteristics. The 64-grain projectile offers a balance suitable for a range of firearm platforms.
The selection of a 64-grain projectile for the Speer Gold Dot 5.56 64 gr cartridge reflects a deliberate balance between various ballistic factors.
