The 5.7×28’s small size and lightweight design allow it to achieve high velocities. Translating to excellent penetration and a flat trajectory. This makes it a highly efficient cartridge for longer-range shots compared to standard handgun rounds like the 9mm.
Ballistics Overview: Where 5.7x28mm Shines
One of the 5.7x28mm cartridge’s most defining features is its impressive ballistics. Because of its small bullet size and high velocity, the round can achieve armor penetration while maintaining a relatively low level of recoil. This makes it easy to handle, even in rapid-fire situations.
- Velocity: With velocities reaching up to 2,500 feet per second (fps) in longer barrels, the 5.7x28mm far outpaces traditional handgun rounds like the 9mm, which typically max out around 1,200 fps.
- Energy: Despite its small size, the 5.7x28mm bullet’s high velocity gives it sufficient energy for personal defense situations. Depending on the bullet weight and barrel length, it typically produces between 250 and 450 foot-pounds of energy at the muzzle.
- Penetration: The 5.7x28mm is designed to penetrate soft body armor, making it a unique option for those needing a cartridge that can pass through tough barriers while still being manageable.
Because the 5.7x28mm is a high-velocity round, it is well-suited for longer barrel firearms like carbines and rifles, though it can also be effective in pistols like the FN Five-seveN. When fired from a pistol, expect slightly reduced muzzle velocity and energy, but the cartridge still maintains its ballistic advantages over many other rounds.
Best Uses: 5.7x28mm Cartridge
From plinking on the range, to self-defense, and hunting, the 5.7x28mm cartridge is highly versatile.
The 5.7x28mm cartridge is highly versatile, making it suitable for a range of applications, including:
- Target Shooting and Plinking: The 5.7×28’s flat trajectory and low recoil make it ideal for range practice and recreational shooting.
- Self-Defense and Home Defense: With its armor-piercing capabilities and high velocity, the 5.7x28mm is a great option for personal protection, especially when barriers or soft armor may be a concern.
- Small Game Hunting: The 5.7×28 mm’s high velocity and accuracy make it a solid choice for hunting small game, particularly with expanding rounds like the FN V-Max.
5.7×28 VS 9mm: A Quick Comparison
The 9mm Parabellum is one of the most popular handgun cartridges in the world, and many potential buyers of the 5.7x28mm wonder how it stacks up against this tried-and-true round. Here are some key differences between the 5.7x28mm and the 9mm:
- Velocity: The 5.7x28mm typically has almost double the velocity of a standard 9mm round, with speeds up to 2,500 fps compared to the 1,200 fps typical of 9mm. This makes the 5.7x28mm more capable of long-range shots and better at penetrating soft armor.
- Recoil: Both rounds are known for their relatively low recoil, but the 5.7x28mm often feels lighter due to its smaller bullet and higher velocity.
- Stopping Power: The 9mm generally has greater stopping power because it fires heavier bullets (115-147 grains), whereas the 5.7x28mm fires lighter bullets (27-40 grains). However, the 5.7x28mm makes up for this with its ability to penetrate soft armor and barriers.
- Capacity: Due to its smaller size, firearms chambered in 5.7x28mm can typically hold more rounds than their 9mm counterparts. For example, the FN Five-seveN holds 20 rounds compared to most 9mm pistols, which hold 15-17 rounds standard.
Both cartridges have their strengths, but the 5.7x28mm offers more versatility in range, penetration, and capacity. In contrast, the 9mm remains the go-to choice for raw stopping power and availability.
A Brief History: 5.7x28mm Cartridge
FN Herstal developed the 5.7x28mm cartridge in response to a NATO request in the late 1980s. At the time, NATO wanted a new PDW cartridge to replace the 9mm Parabellum. The requirement was that it offered superior armor-piercing capability with minimal recoil. The result was the 5.7x28mm, designed to penetrate soft body armor while being lightweight and low-recoil, ideal for close-quarters combat.
The first weapon chambered for the 5.7x28mm was FN’s P90 PDW, which gained popularity in military and law enforcement circles. FN also developed the Five-seveN pistol the P90. Making the 5.7x28mm a versatile cartridge suitable for both rifles and handguns.
Although initially designed for military use, the cartridge has since gained a following among civilians for self-defense, target shooting, and even hunting small game. Its unique combination of high velocity, low recoil, and flat trajectory makes it stand out from other cartridges like the 9mm, especially in niche use cases.
Big Fun: Best 5.7×28 Ammo
If the greatest luxury is being able to live life by your own terms, the 5.7x28mm cartridge is living the high life.
There’s no two ways around it, 5.7×28 is a niche caliber. It didn’t end up replacing the 9mm cartridge but created its own following in the personal defense category. Decades after its introduction, myths and wild speculation about its performance have largely been put to rest. However, it has shown to have serious staying power, even though it comes at a cost for enthusiasts.
The 5.7×28 ammo cartridge offers a unique combination of high velocity, low recoil, and impressive penetration. It’s a versatile choice for a variety of shooting needs. Whether you’re looking for ammo for plinking, self-defense, or specialized purposes, the 5.7x28mm provides options that many other calibers simply can’t match.
