The .375 CheyTac: A Comprehensive Overview of Ballistics, Performance, and Applications

The .375 CheyTac cartridge has carved a significant niche in the world of long-range shooting and military applications. Known for its exceptional ballistic performance and accuracy at extended distances, the .375 CheyTac has become a favorite among competitive shooters, law enforcement, and military personnel. This article delves into the history, specifications, performance characteristics, and applications of the .375 CheyTac, providing a comprehensive understanding of this powerful round.

A Brief History of the .375 CheyTac

The .375 CheyTac was developed by CheyTac USA in the early 2000s as a long-range cartridge designed for extreme accuracy. The primary goal was to create a round that could effectively engage targets at distances exceeding 2,000 meters. The development team focused on optimizing the bullet’s ballistic coefficient and stability to minimize the effects of wind drift and bullet drop over long distances. The .375 CheyTac quickly gained recognition for its superior performance compared to other long-range cartridges of the time.

Technical Specifications of the .375 CheyTac

Understanding the technical specifications of the .375 CheyTac is crucial for appreciating its performance capabilities. Key specifications include:

Bullet Diameter: .375 inches (9.5 mm)
Neck Diameter: .404 inches (10.3 mm)
Base Diameter: .534 inches (13.6 mm)
Case Length: 3.042 inches (77.3 mm)
Overall Length: 4.173 inches (106 mm)
Case Capacity: Approximately 146 grains of water
Primer Type: Large Rifle

These dimensions contribute to the cartridge’s high muzzle velocity and exceptional ballistic coefficient, enabling it to maintain accuracy and energy over extreme distances. The .375 CheyTac is typically loaded with heavy, low-drag bullets ranging from 350 to 400 grains.

Ballistic Performance: Velocity, Energy, and Trajectory

The ballistic performance of the .375 CheyTac is where it truly shines. The cartridge is known for its high muzzle velocity, flat trajectory, and retained energy at long ranges. Typical performance metrics include:

Muzzle Velocity: 2,900 to 3,200 feet per second (fps), depending on the specific load and barrel length.
Muzzle Energy: 7,000 to 8,000 foot-pounds (ft-lbs).

The high muzzle velocity and energy allow the .375 CheyTac to maintain a relatively flat trajectory, reducing the need for significant elevation adjustments when engaging targets at varying distances. Its superior ballistic coefficient minimizes the effects of wind drift, making it easier to achieve accurate shots in challenging environmental conditions. Compared to cartridges like the .338 Lapua Magnum, the .375 CheyTac generally exhibits a flatter trajectory and greater retained energy at extreme ranges.

Accuracy and Effective Range of the .375 CheyTac

Accuracy is paramount in long-range shooting, and the .375 CheyTac is renowned for its precision. With proper rifle setup and skilled marksmanship, the .375 CheyTac is capable of sub-MOA (Minute of Angle) accuracy. This means that the cartridge can consistently place shots within a 1-inch group at 100 yards, a level of precision that is essential for engaging small targets at long distances.

The effective range of the .375 CheyTac extends well beyond 2,000 meters (approximately 2,187 yards). In practical applications, skilled shooters have successfully engaged targets at distances exceeding 2,500 meters. This capability makes the .375 CheyTac a valuable tool for military snipers and long-range shooting enthusiasts who require extreme precision at extended ranges.

Rifles Chambered in .375 CheyTac

Several manufacturers produce rifles chambered in .375 CheyTac, each with its own features and design characteristics. Some of the most well-known rifles include:

CheyTac Intervention: The rifle for which the cartridge was originally designed, known for its advanced features and long-range accuracy.
EDM Arms Windrunner: A modular, bolt-action rifle that offers excellent performance and reliability.
Desert Tech HTI: A multi-caliber platform that can be configured for .375 CheyTac, providing versatility and adaptability.

These rifles are typically equipped with heavy barrels, advanced optics, and adjustable stocks to enhance accuracy and shooter comfort. The choice of rifle depends on individual preferences and specific application requirements.
