Hornady 300 Rem Ultra Mag

Hornady 300 Rem Ultra Mag (RUM) Brass brass is produced with precision, tight uniform tolerances, concentricity, weight, and capacity.  As a result, tight wall concentricity helps to ensure proper bullet seating in both the case and the chamber of your firearm.  This also aids in a uniform release of the bullet on firing, for optimal velocity and accuracy.


This is not loaded ammunition.
