Superior Plated Features Berry s Hybrid Hollow Points are the result of two merged developmental ideas. Following the same process as our Superior Plated Bullets they start with a swaged lead core that is then electroplated with copper to final weight. Lastly they are re-struck to ensure precise specifications and create the Hybrid Hollow Point nose design. This design allows for maximum expansion and weight retention becoming one of the most reliable self defense bullets available today. The 380 s penetration is 8-9. THIS IS NOT LOADED AMMUNITION.
