5.7×28 Ammo Comparison: A Comprehensive Guide for 2024

The 5.7x28mm cartridge, a relative newcomer to the ammunition scene, has carved out a significant niche for itself. Originally developed by FN Herstal in the late 1980s, the 5.7×28 was designed as a companion cartridge to the FN P90 personal defense weapon (PDW) and the FN Five-seveN pistol. Its high velocity, flat trajectory, and relatively low recoil have made it a popular choice for military, law enforcement, and civilian shooters alike. This 5.7×28 ammo comparison aims to provide a detailed overview of various 5.7×28 ammunition types, their performance characteristics, and ideal applications. We will delve into different bullet weights, construction materials, and manufacturer offerings, providing you with the information needed to make an informed decision for your specific needs.

Understanding the 5.7×28 Cartridge

Before diving into a 5.7×28 ammo comparison, it’s crucial to understand the cartridge’s unique design and performance characteristics. The 5.7×28 is a small-caliber, high-velocity bottleneck cartridge. Its small diameter allows for higher magazine capacity compared to traditional handgun rounds like 9mm or .45 ACP. The bottleneck design contributes to its excellent ballistic performance, enabling a flatter trajectory and extended effective range. The reduced recoil makes it easier to control, especially in rapid-fire scenarios. The 5.7×28 ammo is often favored in PDWs like the FN P90 because of these features. However, the performance of 5.7×28 ammo can vary greatly depending on the specific load.

Key Factors in 5.7×28 Ammo Comparison

Several factors come into play when conducting a 5.7×28 ammo comparison. These factors significantly impact the cartridge’s performance in different scenarios. Understanding these aspects will help you choose the right ammunition for your specific needs:

Bullet Weight: 5.7×28 bullets typically range from 27 to 40 grains. Lighter bullets generally offer higher velocities and flatter trajectories, while heavier bullets may provide better penetration and energy transfer.
Bullet Construction: The bullet’s construction plays a crucial role in its terminal performance. Options include full metal jacket (FMJ), hollow point (HP), and specialized defense rounds. FMJ rounds are typically used for training and target practice, while HP and specialized rounds are designed for self-defense and law enforcement applications.
Velocity and Energy: Velocity and energy are directly related to the cartridge’s stopping power and effective range. Higher velocity translates to a flatter trajectory and increased energy upon impact.
Manufacturer: Different manufacturers may use different propellants and manufacturing processes, leading to variations in performance. Reputable manufacturers generally offer more consistent and reliable ammunition.
Intended Use: The intended use of the ammunition should be a primary consideration. Target shooting, hunting small game (where legal), or self-defense will dictate the optimal choice.

5.7×28 Ammo Types: A Detailed Comparison

Let’s delve into a detailed 5.7×28 ammo comparison, examining various types available on the market.

FN SS197SR

The FN SS197SR is a popular choice for civilian shooters. It features a 40-grain Hornady V-Max bullet with a polymer tip. This bullet design promotes rapid expansion upon impact, making it a viable option for self-defense. The SS197SR is known for its accuracy and relatively low recoil. It’s a good all-around choice if you’re looking for versatility. However, it may not meet the penetration requirements of some law enforcement agencies.

FN SS195LF

The FN SS195LF is a lead-free, hollow-point round designed for law enforcement and self-defense. It features a 28-grain hollow-point bullet that expands reliably upon impact. The SS195LF offers excellent accuracy and stopping power. Its lead-free construction makes it environmentally friendly. This 5.7×28 ammo is a solid option for those prioritizing responsible shooting.

FN SS198LF

The FN SS198LF is an improved version of the SS195LF. It features a slightly heavier 27-grain hollow-point bullet and a higher velocity. The SS198LF delivers even greater stopping power and a flatter trajectory. This option is primarily available to law enforcement and military personnel. Civilians may find it difficult to obtain.

Federal American Eagle FMJ

Federal American Eagle FMJ 5.7×28 ammo is a 40-grain full metal jacket round designed primarily for target practice and training. It’s a more affordable option compared to the specialized defense rounds. While not ideal for self-defense due to its limited expansion, the FMJ round provides reliable feeding and consistent performance. It’s an excellent choice for high-volume shooters looking to save money. This is a great entry point for those new to the 5.7×28 ammo platform.

Speer Gold Dot

Speer Gold Dot 5.7×28 ammo utilizes a 40-grain Gold Dot hollow point bullet. This round is engineered for consistent expansion and deep penetration, making it a reliable choice for self-defense. Speer Gold Dot ammunition is known for its quality and consistent performance across various calibers. The 5.7×28 Gold Dot is no exception. [See also: Speer Gold Dot Ammunition Review]

Elite Ammunition

Elite Ammunition offers a range of specialized 5.7×28 loads. These are designed for maximum penetration and stopping power. Their offerings include armor-piercing rounds and frangible rounds. However, some of these rounds may be restricted or unavailable to civilian shooters due to legal regulations. Due to the specialized nature of Elite Ammunition, research your local laws before purchasing.

5.7×28 Ammo Performance: Real-World Considerations

While ballistic data provides valuable insights, real-world performance can vary depending on several factors. These include barrel length, firearm type, and environmental conditions. Therefore, it’s crucial to test different types of 5.7×28 ammo in your own firearm to determine which performs best for your specific needs. Consider conducting your own 5.7×28 ammo comparison through live-fire testing. [See also: Ballistic Testing Methods]

Legal and Ethical Considerations

Before purchasing any type of ammunition, including 5.7×28 ammo, it’s essential to understand the legal regulations in your area. Some jurisdictions may restrict the ownership or use of certain types of ammunition, particularly armor-piercing or expanding rounds. Additionally, ethical considerations should always be a priority when choosing ammunition for self-defense. Select ammunition that is effective but minimizes the risk of over-penetration and collateral damage. Responsible gun ownership requires understanding and adhering to all applicable laws and ethical guidelines.

Choosing the Right 5.7×28 Ammo: A Summary

Selecting the right 5.7×28 ammo depends on your specific needs and priorities. If you’re primarily concerned with target practice, a reliable FMJ round like the Federal American Eagle is a cost-effective choice. For self-defense, consider a hollow-point round like the FN SS195LF, FN SS197SR, or Speer Gold Dot. If you require maximum penetration, explore specialized options from manufacturers like Elite Ammunition, but be sure to check local regulations. Ultimately, the best way to determine the optimal 5.7×28 ammo for your needs is to conduct thorough research and testing. Remember to prioritize safety, legality, and ethical considerations in your decision-making process.
