Can This Bullet Made of Powder SAVE Your LIFE?...SinterFire Special Duty AMMO Test!
This video tests SinterFire Special Duty ammunition, a unique sintered (powdered) copper and tin hollow-point round, using ballistic gel and a clothing barrier. The presenter, an experienced firearms instructor, evaluates its performance in 9mm and .380 ACP, focusing on penetration, fragmentation, and velocity. While initially skeptical of its light-for-caliber nature, the results show surprisingly controlled fragmentation and significant penetration from the 9mm core, leading to a re-evaluation of its potential effectiveness.
