Overview

MACH 3 Long Range Ammo

Mach 3 Long Range Ammo Line Provides NGSW level ballistic performance at safe pressures in your existing rifles

  • Provides 300 FPS More Velocity than our standard match ammo

  • Safe Pressures @ 65,000 PSI which is only 5,000 PSI greater than standard brass pressures rather than NSGW’s 80,000 PSI

  • Reduces Loaded Cartridge weight between 12% for 5.56 up to 50% in the 50 BMG.

The MACH 3 bullet line uses SST Case Technology that:

  • Increases case capacity up to 14% increasing which increases velocities up to 300 fps at the same pressure as brass

  • Increases case strength up to 150% allowing cartridge cases to withstand Pressures up to 100k PSI allowing even more velocity.

  • Thinner steel wall thickness reduces loaded ammo weight by 12% for 5.56 up to 50% in the 50 BMG

  • Improved manufacturing Precision allows for tighter chamber fit resulting in improved accuracy
