The Hornady Handgun Hunter .454 Casull 200gr MonoFlex (Hornady part no. 9151) is a .454 Casull hunting load built around a 200-grain MonoFlex bullet. Hornady makes the MonoFlex handgun projectile from a tough copper alloy that achieves deep penetration and 95% weight retention. An elastomer material in the bullet’s open cavity compresses on impact, then pushes out so the bullet expands faster than a standard hollow point design. Each box holds 20 rounds, loaded with premium cases, primers and propellants. It is built for the handgun hunter who wants a bullet made for rough conditions and demanding game.
