Product Information

B&B .375 CT 400gr Precision Bullets — Featuring Warner Tool Flat Line Technology

Designed for serious extreme long-range (ELR) shooters, B&B's .375 CT 400gr precision bullets bring unmatched performance to those pushing the limits of distance. Featuring Warner Tool Company's 400-grain Flat Line projectile, these bullets offer class-leading ballistic coefficients and precision engineering — purpose-built for those who demand absolute performance.

  • Ultra-High Ballistic Coefficient (BC) — Featuring a G1 BC of 1.103 and G7 BC of 0.552, and enhanced with a stabilizing drive ring, these bullets are engineered to reach out to extreme distances while minimizing wind drift.
  • Impressive Muzzle Velocity — When properly loaded, these projectiles are capable of achieving approximately 2,950 feet per second (fps), giving you a flatter trajectory and more retained energy at distance.
  • CNC-Turned Solid Copper Alloy — Precision-machined from solid copper for exceptional consistency, offering superior weight uniformity and concentricity for sub-MOA performance at extreme ranges.
  • Optimized for 1:9” or Faster Twist Rates — Designed to perform in 1:9” or faster twist barrels, ensuring full stability and accuracy for ultra-long-range engagements.
  • Long-Range, Single-Feed Focused Design —  These rounds are intended for shooters who prioritize maximum performance over magazine compatibility. While these may not fit in standard magazines, that’s a good thing — because for precision shooting at extreme distances, you want to focus on one perfect shot at a time. Single-loading ensures maximum cartridge length and optimal seating for ultimate accuracy.
  • Compatible with Leading ELR Rifles — Perfect for .375 CheyTac platforms, including CheyTac M200 Intervention, Cadex CDX-40 Shadow, Gunwerks HAMR, Desert Tech HTI, and other custom-built ELR rifles chambered in .375 CheyTac.

This is loaded ammunition.
