5.7x28mm vs .223 Remington Comparison

In the vast landscape of ammunition types, two calibers have risen to prominence, notably in close-quarters battle (CQB), hunting, and self-defense scenarios - the 5.7x28mm and the .223 Remington. Each bearing its unique set of characteristics, they cater to different needs and preferences. Join us as we delve into an exhaustive comparison of these two calibers, to guide you in making an informed decision.

Historical Backdrop

Understanding the lineage of these two formidable calibers provides a pathway into their intrinsic properties and functionalities.

• 5.7x28mm:
  • Inception: Developed in the 1980s by FN Herstal.
  • Purpose: Initially conceived to replace the 9mm NATO cartridge, focusing on penetration and velocity.
• .223 Remington:
  • Inception: Emerged in the early 1960s, designed by Remington Arms.
  • Purpose: Primarily crafted for the military, eventually finding a home in civilian markets due to its versatility.

Cartridge Specifications

The anatomy of a cartridge is pivotal in determining its performance. Let’s glance through the specific features of each.

• 5.7x28mm:
  • Bullet Diameter: 5.7 mm
  • Case Length: 28 mm
  • Bullet Weight: Generally ranges from 31 to 40 grains
• .223 Remington:
  • Bullet Diameter: 5.56 mm
  • Case Length: 45 mm
  • Bullet Weight: Typically spans 35 to 85 grains

Ballistics

In this section, we delve into the technicalities, from velocity to energy and beyond, to paint a vivid picture of their ballistic profiles.

• 5.7x28mm:
  • Muzzle Velocity: Averages around 2,350 fps
  • Muzzle Energy: Generally hovers around 394 ft-lbs
• .223 Remington:
  • Muzzle Velocity: Can exceed 3,300 fps, depending on the load
  • Muzzle Energy: Often surpasses 1,300 ft-lbs, contingent on the ammunition used

Close Quarters Battle (CQB)

Choosing the right caliber for CQB environments necessitates a focus on agility, control, and stopping power.

• 5.7x28mm: Excels in maneuverability and control, making it suitable for quick response in confined spaces.
• .223 Remington: Its higher energy delivery makes it potent in CQB, albeit with increased recoil.

Hunting Applications

The wild outdoors demands ammunition that combines accuracy with a robust impact.

• 5.7x28mm: Suitable for small game and varmint hunting due to its limited recoil and good accuracy. But in all likelihood, you're not hunting with 5.7 ammo
• .223 Remington: A preferred choice for medium-sized game, offering a greater range and stopping power.

Self/Home Defense

When it comes to safeguarding your haven, the choice of caliber is critical.

• 5.7x28mm: Its lower recoil and high capacity magazines make it a viable option for home defense.
• .223 Remington: Favored for its stopping power, but one must consider its penetration which might pose over-penetration risks in home settings.

What is the Effective Range of 5.7x28mm Ammo?

The effective range of 5.7x28mm ammunition can vary based on several factors including the specific firearm being used, the exact load of the ammunition, and the skill of the shooter. However, it is generally agreed that the effective range for this caliber is around 200 meters (approximately 220 yards) for a trained shooter aiming at a man-sized target. Within this range, the 5.7x28mm cartridge is known to maintain relatively flat trajectory and retain sufficient energy to be effective in various applications including self-defense and tactical situations. This cartridge was designed to bridge the gap between traditional pistol ammunition and rifle ammunition, providing a higher velocity and flatter trajectory than most pistol calibers, while still being usable in a compact firearm. It’s important to note that when we speak of "effective range," we are referring to the distance at which the ammunition can still produce reliable terminal ballistics for its intended use, and not simply the distance it can travel. Moreover, while 200 meters is a commonly cited effective range, users can potentially achieve accurate shots at longer distances with well-placed shots, especially when using optimized firearms and ammunition for extended ranges. It is always recommended to understand and experiment with any ammunition type within controlled environments to fully grasp its potential and limitations.

Verdict: Which Caliber is Superior?

Superior is always a subjective term and these calibers are no exception. If you don't own an AR-15 and you're choosing between firearms chambered in 223 vs 5.7:, go with a firearm in .223 (or 5.56) due to its greater versatility, its also cheaper to shoot. On the other hand if you already have an AR or two (or twelve), put a firearm chambered in 5.7x28mm on your list, its incredibly fun, amazing ballistics.

• 5.7x28mm: Stands as a versatile option, catering to modern self-defense needs, showcasing precision and control. With firearms like FN Five-Seven pistol and now the Smith & Wesson 5.7x28, Ruger 57, CMMG Dissent MK57, Ruger LC Charger and Keltech P50, Ruger LC Carbine, CMMG Banshee MK57, and the FNH PS90 and others, shooters have more options than ever to shoot this awesome caliber and we fully expect more firearm manufacturers to make models chambered in 5.7x28mm. The biggest negative with 5.7 ammo is the expense, it is a little pricier than 223 Rem ammo, so if you're looking for your first, second or third firearm, we would recommend a traditional AR-15 chambered in 5.56 NATO (which can shoot both 5.56 ammo and 223 Rem) if you already have several guns and looking for an excellent shooting experience with a handgun that can shoot 1,000 yards on a rope with little recoil, then this is your caliber.
• .223 Remington: Presents itself as a powerhouse, providing a broad spectrum of utilities, from hunting to defense.

The journey through the landscapes of the 5.7x28mm and the .223 Remington unveils a rich tapestry of features, functionalities, and historical intricacies. While the 5.7x28mm impresses with its modern innovations, control, and agility, the .223 Remington stands tall with its formidable stopping power and versatility.
