MORE Powder For More POWER?...10MM & .40S&W Sinterfire Self-Defense AMMO Test!
This video tests Sinterfire Special Duty self-defense ammunition in 10mm Auto and .40 S&W calibers using ballistics gel. The test focuses on projectile fragmentation, penetration, and velocity differences between the two calibers with identical 125-grain projectiles. While both calibers demonstrated significant fragmentation and energy dump, the instructor expresses reservations about the lightweight nature of the projectiles for self-defense applications, particularly for the 10mm.
