Will a 10mm Auto Penetrate Drywall (Gypsum)?

Yes — defeats a 13 mm drywall (gypsum) barrier

Fired at the muzzle, a representative 10mm Auto load (11.7 g, FMJ, 380 m/s) reaches roughly 357 mm (14.1 inches) into drywall (gypsum). That is enough to defeat a typical barrier of this material — treat anything behind it as exposed.

About Drywall (Gypsum)

One sheet of interior drywall is ~13 mm; a wall is two sheets and a gap.
