Key features of this round include:

- Blunt nose for effective initial energy transfer and straight, deep penetration, along with dependable magazine feeding
- Solid copper build with cutting edges to break through barriers without deformation or deflection
All Underwood Ammo rounds feature flash-suppressed powder to preserve vision in low-light conditions, ensuring you’re ready for any situation. Each round is field-tested with popular, real-world firearms to simulate practical conditions.
