Comparing 400 Legend and 5.56 NATO: Which Caliber is Right for You?
When choosing the right caliber for your rifle, it’s important to consider various factors such as intended use, ballistics, and recoil. Among the many options available today, two popular calibers stand out: the .400 Legend and the 5.56 NATO. While both offer impressive capabilities, they each have unique characteristics that make them ideal for different applications. In this blog, we’ll compare these two calibers to help you decide which is the best fit for your needs.
1. Overview of the 400 Legend
The .400 Legend is a relatively new cartridge that was introduced by Winchester in 2019. It was designed specifically for the AR-15 platform, offering hunters and sports shooters a powerful round with better stopping power than traditional 5.56 NATO rounds. The .400 Legend is chambered in a .40-caliber bullet, typically weighing between 160 and 220 grains, and is ideal for medium to large game hunting. It delivers significantly more energy than the 5.56 NATO, which makes it a great choice for hunters seeking more knockdown power in a semi-automatic platform.
Key Features of the .400 Legend:
- Bullet Size: .40 caliber (160–220 grain)
- Velocity: Around 2,200 to 2,400 feet per second
- Energy: Typically ranges from 1,500 to 2,000 foot-pounds
- Effective Range: 200 to 300 yards
- Ideal Use: Hunting medium to large game, home defense, and tactical applications
2. Overview of the 5.56 NATO
The 5.56 NATO has long been the standard caliber for military rifles worldwide, most notably used in the M16 and M4 platforms. Known for its high velocity and relatively low recoil, the 5.56 NATO is incredibly versatile. It is commonly used for a wide range of applications, including military and law enforcement purposes, varmint hunting, and target shooting. The 5.56 NATO typically uses a 55 to 77 grain bullet and is chambered in a smaller .223-inch diameter.
Key Features of the 5.56 NATO:
- Bullet Size: .223/5.56 caliber (55–77 grain)
- Velocity: Around 3,000 to 3,300 feet per second
- Energy: Typically ranges from 1,200 to 1,500 foot-pounds
- Effective Range: 400 to 600 yards
- Ideal Use: Target shooting, varmint hunting, self-defense, and military applications
3. Performance and Ballistics Comparison
Accuracy and Range: The 5.56 NATO has a clear advantage when it comes to effective range. With a flatter trajectory and higher velocity, the 5.56 NATO can reliably hit targets at ranges of up to 600 yards. In comparison, the .400 Legend is effective at shorter ranges—typically between 200 and 300 yards—due to its larger bullet and slower velocity. However, the .400 Legend's larger bullet does carry more energy, making it effective for close-range engagements where more stopping power is necessary.
Recoil: Recoil is another important factor when choosing a caliber. The 5.56 NATO is known for its low recoil, making it ideal for fast follow-up shots and accurate shooting over long periods of time. The .400 Legend, with its larger bullet and more powerful charge, has more noticeable recoil. However, this added recoil is generally manageable in an AR-15 platform, but shooters new to high-recoil calibers may need to spend some time getting used to it.
Stopping Power: When it comes to stopping power, the .400 Legend takes the lead. Its larger, heavier bullet is designed for hunting and self-defense, offering significant expansion upon impact. The 5.56 NATO, while still effective for defense, has less stopping power compared to the .400 Legend. Its smaller bullet size and velocity make it better suited for penetrating soft targets or light game, but it lacks the deep tissue damage and energy transfer that larger calibers like the .400 Legend provide.
4. Cost and Availability
In terms of cost, the 5.56 NATO is the more affordable and widely available option. Due to its widespread use, 5.56 NATO ammunition is mass-produced and can be found at virtually any firearms retailer. It’s also relatively inexpensive, making it ideal for regular practice and training.
On the other hand, the .400 Legend is a newer cartridge, which means it’s less common and more expensive. While prices have become more reasonable as demand increases, you may still find it harder to source ammo in certain areas, and it may be slightly pricier than 5.56 NATO.
5. Which Caliber is Right for You?
The choice between the .400 Legend and the 5.56 NATO ultimately depends on your specific needs and intended use.
-
Choose the 5.56 NATO if you’re looking for:
- A versatile, lightweight caliber for target shooting and varmint hunting
- Lower recoil for fast follow-up shots
- A widely available and affordable round for frequent practice
-
Choose the .400 Legend if you’re looking for:
- Greater stopping power for hunting medium to large game or self-defense
- A unique caliber that offers the power of larger cartridges in an AR-15 platform
- A round designed for closer-range engagements with more energy transfer upon impact
Final Thoughts
Both the .400 Legend and the 5.56 NATO have their own distinct advantages. The 5.56 NATO is a tried-and-true, versatile choice for various applications, while the .400 Legend offers powerful stopping power for those who need more punch in their rifle. Consider what you value most—whether it’s range, recoil, or power—before making your decision. Either way, both calibers provide excellent performance in their respective fields.
