This bullet was designed with one thing in mind and that was to shoot 1000 yards in a 308 Winchester. To accomplish that we added length to the boattail and engineered a forgiving tangent ogive with a closed nose. Doing this gave it a .527 BC which keeps it super sonic past 1000 yards in a 308 chamber. This bullet is basically a redesign of the legendary 168MK which we will continue to manufacture. Anyone that enjoys shooting medium to long range with a 308 or even the big magnums will love this bullet.
