This video tests the durability of a 1951 Mueller fire hydrant against various firearms, from 9mm to .50 BMG AP rounds. Surprisingly, even the .50 BMG AP rounds failed to fully penetrate the cast iron hydrant, stopping all tested calibers. The test also assessed projectile penetration and the effectiveness of the hydrant as a ballistic barrier.
This video tests the ballistic resistance of a vintage cast iron fire hydrant against various firearms, from 9mm to .50 BMG. Surprisingly, even a .50 BMG round, including an Armor Piercing Incendiary (API) variant, failed to fully penetrate the hydrant, though it caused significant damage. Handgun rounds had minimal effect, while a 12 gauge slug and rifle rounds penetrated the first wall but were stopped by internal structures.
This video demonstrates the destructive power of a 20mm rifle against a cast-iron fire hydrant. The initial shot created a clean entry and a jagged exit hole, while a second shot with a practice round completely shattered the hydrant's body. The experiment highlights the brittle nature of cast iron when subjected to high-velocity impacts and the significant energy of 20mm ordnance.
