Overview
Built for hunters who want a controlled-expansion bullet with a focus on accuracy, this 6.5mm 130-grain option is designed for use in a wide range of hunting applications. Its construction is described as combining a polymer tip, tuned ogive, and boat tail design to support stable flight and consistent performance at distance. The jacket and core design are intended to balance expansion with weight retention, making it a practical choice when penetration and terminal effect both matter. This is a bullet only, not loaded ammunition, and it requires a barrel twist rate of 1:8 or faster.
