5.7 x28mm vs 223

Choosing the right ammunition depends heavily on its intended purpose. While both 5.7x28mm and .223 Remington are popular cartridge choices, they cater to vastly different needs. This comprehensive comparison will delve into the key differences between these two calibers, helping you make an informed decision based on your specific requirements.

Ballistics and Performance: A Head-to-Head

The most significant difference lies in their ballistic characteristics. The 5.7x28mm, developed by FN Herstal, is a smaller, higher-velocity round designed for personal defense and close-quarters combat. Its smaller size allows for higher magazine capacity in compact weapons. The .223 Remington, on the other hand, is a more established and widely used intermediate cartridge known for its accuracy and stopping power at longer ranges.

Velocity and Energy:

  • 5.7x28mm: Boasts significantly higher muzzle velocity, resulting in a flatter trajectory and less bullet drop at longer ranges (relative to its design purpose). However, its smaller size means less overall energy transfer upon impact.

  • .223 Remington: Delivers considerably more kinetic energy than the 5.7x28mm, making it more effective against larger targets or at longer distances. Its lower velocity leads to a more pronounced bullet drop.

Penetration and Stopping Power:

  • 5.7x28mm: Known for its ability to penetrate soft body armor, though its relatively low mass may limit its stopping power against larger targets. The design often prioritizes penetration over massive energy transfer.

  • .223 Remington: Generally offers superior stopping power compared to the 5.7x28mm due to its greater mass and energy transfer. Penetration can vary significantly depending on bullet construction.

Applications and Uses:

The intended use cases drastically differentiate these two calibers.

5.7x28mm: Ideal Applications

  • Personal Defense: Its high capacity magazines and armor-piercing capabilities make it a compelling choice for personal protection in scenarios where close-quarters engagements are expected.
  • Law Enforcement: Some specialized law enforcement units utilize the 5.7x28mm due to its potential to penetrate lightweight body armor.
  • Sporting: While less common, it finds a niche in some competitive shooting disciplines.

.223 Remington: Ideal Applications

  • Hunting (small game): Effective for hunting smaller animals like coyotes, foxes, and prairie dogs.
  • Sport Shooting: Extremely popular in target shooting and various competitive shooting sports.
  • Military and Law Enforcement: Widely used by military forces and law enforcement agencies worldwide for its versatility and availability.

Weaponry and Availability:

Both calibers are readily available, although the 5.7x28mm typically has a smaller selection of firearms compared to the .223 Remington. The .223 Remington is found in a vast array of firearms, from AR-15 platform rifles to various handguns, making it incredibly versatile.

Conclusion: Choosing the Right Cartridge

The "better" cartridge depends entirely on your specific needs. The 5.7x28mm excels in close-quarters combat scenarios where penetration of light body armor is a priority. Its high-velocity and high-capacity magazines make it a formidable option for personal defense and specialized law enforcement applications. However, its lower energy transfer means it may be less suitable for hunting or long-range engagements.

The .223 Remington is a much more versatile round, offering superior stopping power and accuracy at longer ranges. Its widespread availability and compatibility with a multitude of firearms make it a popular choice for hunting, sport shooting, and military/law enforcement applications. Ultimately, careful consideration of your intended use, target engagement range, and desired stopping power will determine which caliber best suits your requirements.
