Is It REALLY That Much BETTER?.....357 Sig vs 9MM +P+ Self-Defense AMMO Test!
This expert-level analysis compares .357 Sig and 9mm +P+ self-defense ammunition using rigorous testing protocols. The .357 Sig demonstrated superior velocity and energy, resulting in more significant temporary cavity disruption and fragmentation, while the 9mm +P+ showed good penetration and expansion with less fragmentation. The video highlights the importance of detailed ballistic testing for understanding ammunition performance in self-defense scenarios.
