Will a 10mm Auto Penetrate Concrete?

No — stops inside concrete (reaches 47 mm of a 100 mm barrier)
Penetration depth
47 mm (1.8″)
Impact velocity

Muzzle energy

Bullet behaviour
Intact

Fired at the muzzle, a representative 10mm Auto load (11.7 g, FMJ, 380 m/s) reaches roughly 47 mm (1.8 inches) into concrete. It loses its energy before defeating a typical barrier of this material.
