Hornady's hard-hitting and deep-penetrating, GMX bullet combines monolithic construction with pioneering ballistic design to meet the need for a premium, non-traditional bullet. Featuring a long, sleek profile with cannelures, the design reduces overall bearing surface and drag, while achieving some of the highest ballistic coefficients from monolithic, non-traditional bullets. It utilizes a tough mono-metal copper alloy which has been proven to shoot cleaner, foul less, and deliver consistent, while the hard polymer tip drives into the hollow cavity at the front of the bullet, creating a mushroom-style projectile as it travels through the animal.
