.300 Blackout vs 9mm | Real-World Penetration Test (Drywall, Cars & More!)
This test compares .300 Blackout and 9mm penetration through common barriers like drywall, car doors, and body armor. .300 Blackout demonstrated significantly higher energy transfer and penetration potential, causing more extensive damage to drywall and studs. Both calibers penetrated car doors easily, highlighting their limited effectiveness as cover. Level 3A body armor stopped all tested rounds but showed significant backface deformation.
