Oxygen Tanks are Bulletproof ?
This video tests the bullet resistance of an empty oxygen tank against various calibers. While smaller handgun rounds like .22 LR and 9mm only cause surface marks, higher-powered rounds like the .500 S&W Magnum and .50 BMG with standard rounds penetrate the first wall. Only .50 BMG Armor Piercing Incendiary (API) rounds achieved full penetration through both sides of the tank.
