Hornady’s 300 Winchester Magnum unprimed brass (item number 8670) is manufactured in smaller batches to uphold rigorous quality standards, delivering 50 rounds per box for serious reloaders. Each case arrives unprimed and ready for your custom reloading process.
Every Hornady case is measured for consistently tight wall concentricity and run through a pressure calibration test to ensure uniform case expansion during firing. This precision manufacturing means each case is virtually identical to other Hornady cases in the same caliber, producing consistent pressures, velocity, and accuracy with every reload. The meticulous attention to detail allows you to get more reloads from Hornady brass.
These cases deliver excellent uniformity in wall thickness, weight, and internal capacity. Precise case dimensions allow proper bullet seating in both the case and chamber, while higher concentricity ensures uniform bullet release on firing for optimal velocity and accuracy. Built for hunters and precision shooters pursuing long-range performance with reliability you can trust shot after shot.
