Why Copper Solid Design Matters

The copper solid construction offers several advantages for the defensive shooter. Without a jacket to separate from the core, you get predictable performance through intermediate barriers. The design promotes controlled expansion while maintaining the velocity and energy needed for effective stopping power.
