Berry's Hybrid Hollow Points combine two advanced developmental techniques to create one of the most reliable self-defense bullets available today. Using the same process as our Superior Plated Bullets, each bullet begins with a swaged lead core, which is electroplated with copper to reach the final weight. The bullets are then re-struck to ensure precise specifications and to shape the Hybrid Hollow Point nose design. This unique design maximizes expansion and weight retention, delivering exceptional performance. For 9mm rounds, the penetration depth ranges from 11 inches to 13 inches, making them highly effective for self-defense situations.
