The .375 CheyTac cartridge was developed in the early 2000s by CheyTac USA, with the primary goal of pushing the limits of extreme long-range shooting. Its design roots trace back to the .408 CheyTac, which itself is a product of the military’s search for a cartridge that could engage targets at distances far beyond standard sniper offerings like the .338 Lapua Magnum. The .375 CheyTac was created to provide a flatter trajectory, less wind drift, and significant energy retention at distances exceeding 2,000 yards. Since its introduction, the .375 CheyTac has attracted the attention of both civilian long-range shooting communities and military/law enforcement agencies aiming for precision at ultra-long distances.
The applications of the .375 CheyTac primarily revolve around extreme long-range (ELR) shooting disciplines. Competitive ELR matches, where marksmen engage targets at up to two miles or more, have increasingly popularized this caliber. Its high ballistic coefficient and supersonic capability out to unprecedented distances make it a favorite among those who operate beyond 1,500 yards. While not commonly used for general hunting due to its size and power, it does see sporadic use in specialized scenarios, such as guided hunts for very large game animals where exceptionally long shots may be required. Military and law enforcement applications have also leveraged the .375 CheyTac for specialized roles, particularly in scenarios where anti-materiel performance with pinpoint accuracy at extended ranges is needed.
When it comes to target species, the .375 CheyTac’s immense power, flat shooting trajectory, and retained energy at long range make it most suitable for large and tough game. In North America, this includes species like elk, moose, and even larger animals such as bison or brown bear, provided the shooter is skilled and able to ensure proper shot placement at distance. Globally, it’s sometimes selected for dangerous game in African safaris, but its most common application remains competition and specialized military/LE roles. Most ethical hunters would reserve the .375 CheyTac for scenarios requiring shots well past normal hunting distances, always prioritizing humane takedowns.
Bullet weights for the .375 CheyTac are generally focused on maximizing ballistic efficiency. Typical projectiles range from 350 to 400 grains, with 350 and 375-grain bullets being the most common choices among precision shooters. These bullets are often very long, high ballistic coefficient (BC) designs, such as solid copper match projectiles or very-low-drag (VLD) jacketed offerings, which help maintain supersonic velocities out past 2,500 yards under ideal conditions. Case capacity is considerable, accommodating large powder charges suitable for these heavy bullets, which results in significant muzzle energy and flat trajectories. The case itself is based on the .400 Taylor Magnum, necked down to accept .375-caliber bullets, offering reloaders flexibility for experimentation with seating depths, powder selection, and overall cartridge length—key factors for tuning precision loads. Overall, the .375 CheyTac stands as a premier choice for reloaders and shooters seeking to break performance barriers in the extreme long-range shooting community.
