Understanding the Basics

What is the 350 Legend?

The 350 Legend is a relatively new player in the world of rifle calibers.

Introduced by Winchester in 2019, it was designed to be a versatile and efficient round, particularly for hunters. The 350 Legend boasts a straight-walled casing, making it compliant with hunting regulations in several states where bottleneck cartridges are not permitted.

Its design is a unique blend of power and efficiency, offering a lower recoil compared to other calibers in its class.

Key Specifications:

  • Bullet Diameter: 0.357 inches
  • Case Length: 1.71 inches
  • Typical Bullet Weight Range: 145-265 grains
  • Muzzle Velocity: 2,000 to 2,500 feet per second

What is the 300 Blackout?

The 300 Blackout, also known as 300 AAC Blackout, has a more tactical origin.

Developed by Advanced Armament Corporation and Remington, it was designed to achieve similar performance to the 7.62x39mm round in a cartridge that would be compatible with the standard AR-15 platform.

This caliber gained popularity for its versatility, being effective for both supersonic and subsonic applications, making it a favorite among both hunters and tactical shooters.

Core Characteristics:

  • Bullet Diameter: 0.308 inches
  • Case Length: 1.368 inches
  • Typical Bullet Weight Range: 110-220 grains
  • Muzzle Velocity: 1,000 to 2,800 feet per second (depending on bullet weight)

Both the 350 Legend and the 300 Blackout were born out of a need for specific use cases, with the former focusing on hunting compliance and efficiency, and the latter on tactical versatility.

As we dive deeper into their ballistic performance, ammunition options, and use cases, the distinct advantages of each caliber will become more apparent.

Ballistic Performance Comparison

Understanding the ballistic performance of the 350 Legend and 300 Blackout is crucial for shooters to determine which caliber best suits their needs. This comparison will focus on muzzle velocity, energy, effective range, and accuracy.

Muzzle Velocity and Energy

350 Legend:
