Berry's Hybrid Hollow Points are the product of two advanced developmental concepts combined to create a highly effective self-defense bullet. Manufactured using the same process as our Superior Plated Bullets, each bullet starts with a swaged lead core, which is electroplated with copper to achieve the final weight. The bullet is then re-struck to ensure exact specifications and shape the Hybrid Hollow Point nose design. This design is engineered to offer maximum expansion and excellent weight retention, making it one of the most reliable self-defense bullets available today. For 9mm rounds, the penetration depth ranges from 11 inches to 13 inches, ensuring effective stopping power when needed.
