Black Hills Shooters Supply Starline Unprimed Brass -
Ensure a reliable, high performance load every time with Starline Unprimed Brass. Made of premium brass comprised of 70 percent copper and 30 percent zinc, these cases are vertically drawn to hold wall thickness variation to a minimum. Engineered and built in-house, the bunter tools used to impact the primer pocket during heading provide complete control of the primer pocket diameter and consistently provides a good radius at opening for ease in priming and a perfect burr-free flash hole every time. Every case is run through our final inspection machines to guarantee 100% flash hole presence, correct length and diameter.
