Navy SEAL test Ballistics through Walls | Tactical Rifleman
This test evaluates ballistic penetration through various common wall materials to assess home defense over-penetration risks. Results show that while brick and cinder block offer significant resistance, standard interior drywall and exterior siding/siding offer minimal protection against common defensive calibers like 9mm and 12-gauge buckshot. The 5.56mm round showed surprising fragmentation in drywall, reducing penetration compared to pistol rounds.
