Many customers have recently been asking for ballistics information on the 400gr .408 CheyTac cartridge now available. We have acquired the .408CT data table showing velocity, energy and path over distances up to 1000 yds. The round itself has a ballistics coefficient of .872. This cartridge is suitable for use in the THOR M408, THOR XM408, CheyTac M200, CheyTac M310 and THOR TR408 rifles.
The projectile is CNC lathe turned to ensure maximum uniformity. The results shown in the table below came from ammunition loaded with Bertram brass (from Victoria, Australia) in a standard 30″ barrel configuration.
