When it comes to extreme long-range shooting, both the .375 Cheytac and .408 Cheytac stand out as two of the most respected calibers in the precision rifle world. Developed to push the boundaries of distance, power, and accuracy, both calibers offer elite shooters the capability to engage targets well beyond standard ranges. While both rounds share similar roots, they have distinct characteristics that make each suitable for specific shooting applications.
History and Development
Both the .375 and .408 Cheytac cartridges are part of the Cheytac family, originally designed for military and long-range applications. Cheytac rifles, including the renowned M200 Intervention®, have become synonymous with extreme accuracy, achieving record-breaking shots at distances up to 2,500 yards and beyond. The goal behind both rounds was to create a cartridge that could maintain accuracy and minimal bullet drop over incredible distances, with the .408 Cheytac coming first, followed by the development of the .375 Cheytac to offer even flatter trajectories and higher ballistic coefficients.
Ballistic Performance
-
.408 Cheytac:
- Bullet Weight: 419 to 420 grains
- Muzzle Velocity: Approximately 2,850-3,000 feet per second (FPS)
- Energy: Around 7,700-8,000 ft-lbs
- Effective Range: 2,500+ yards
- Ballistic Coefficient (BC): 0.949 (depending on the projectile)
The .408 Cheytac was initially designed to engage targets at extreme distances with high stopping power. With a heavier bullet and significant muzzle energy, this round is often preferred for military and anti-material purposes. It offers incredible terminal ballistics and retains energy over long distances, making it a great choice for penetrating targets at extreme range.
-
.375 Cheytac:
- Bullet Weight: 350 to 375 grains
- Muzzle Velocity: Approximately 3,000-3,200 FPS
- Energy: Around 6,800-7,500 ft-lbs
- Effective Range: 2,500+ yards
- Ballistic Coefficient (BC): 0.988 (depending on the projectile)
The .375 Cheytac was developed to push the performance envelope even further by reducing drag and improving the ballistic coefficient. This results in a flatter trajectory and better wind deflection characteristics compared to the .408. The .375 is often favored in ELR (Extreme Long Range) competitions due to its superior flight characteristics, giving shooters a slight edge in accuracy over long distances.
Accuracy and Long-Range Capabilities
Both rounds are capable of sub-minute of angle (MOA) accuracy at extreme distances, but their designs are optimized for different priorities:
- The .408 Cheytac offers more energy at the target, making it better suited for applications that require both range and penetration power. Its heavier bullet makes it less susceptible to wind drift in certain conditions, but the extra weight can mean a steeper bullet drop over long distances.
- The .375 Cheytac, with its lighter and more aerodynamically efficient bullet, achieves a flatter trajectory and superior wind resistance at longer ranges. This makes it the preferred choice for competitive shooters who prioritize precision and minimal bullet drop over raw stopping power.
Cost and Availability
Both .375 and .408 Cheytac ammunition tend to be expensive and are less commonly available than more mainstream rounds like .338 Lapua Magnum or .50 BMG. Due to the specialized nature of these rounds, they are often hand-loaded by enthusiasts looking to maximize performance, though factory-loaded options exist.
Applications
- .408 Cheytac is often used in military and law enforcement settings for anti-material or sniper roles, where the ability to engage targets with substantial energy is a key consideration.
- .375 Cheytac is favored by extreme long-range competition shooters, particularly for its superior ballistic performance in precision shooting environments. Its flatter trajectory and minimal bullet drift make it ideal for engaging small targets at extreme distances with pinpoint accuracy.
Which is Right for You?
- For Military or Tactical Use: If terminal energy and the ability to engage hard targets at long distances are priorities, the .408 Cheytac is the better choice due to its heavier bullet and greater stopping power.
- For Competitive Shooters: The .375 Cheytac offers better accuracy over extreme distances, making it ideal for ELR competition shooting or any scenario where precision is paramount.
Conclusion
Both the .375 Cheytac and .408 Cheytac are incredible feats of ballistic engineering, designed to excel in the extreme long-range shooting world. The choice between them depends on the shooter's priorities—whether it's power and penetration with the .408 Cheytac, or precision and ballistic efficiency with the .375 Cheytac.
In either case, these rounds represent the pinnacle of extreme long-range shooting technology, offering capabilities that few other calibers can match.
