Hornady Case 450 Marlin UnprimedAt Hornady,® brass is the foundation for what could be the most memorable shot of your lifetime. Extra time and care is taken in the creation of our cases, producing smaller lots that meet strict quality standards.Our cases offer reloaders excellent uniformity in wall thickness, weight and internal capacity. We measure for consistently tight wall concentricity and even run our cases through a pressure calibration test to ensure uniform case expansion during firing.Our cases allow proper seating of the bullet, not only in the case, but in the chamber as well. High quality brass contributes to consistent charges and pressures.
