The Hornady Back Country 454 Casull ammunition delivers devastating terminal performance with precision engineering for serious hunting applications. This premium cartridge features a 300-grain MonoFlex bullet specifically designed to handle the extreme pressures and velocities of the 454 Casull while maintaining exceptional accuracy downrange.

What Makes This Different
