B&B Firearms, .375 Ammunition, 400gr Precision

B&B .375 CheyTac 400gr Ammo is purpose-built for extreme long-range (ELR) shooters who demand repeatable precision, high retained velocity, and outstanding wind performance. Loaded around a 400-grain CNC-turned solid copper alloy projectile with an exceptionally high ballistic coefficient, this ammunition is designed to keep your data tight and your impacts consistent at mile-plus distances.

Single-feed focused design: These cartridges are optimized for maximum performance rather than standard magazine compatibility. Many shooters prefer single-loading for ELR work because it allows maximum cartridge length and ideal bullet seating for the most consistent accuracy.
