This video tests the durability of a hardened steel lock against progressively larger calibers of firearms. Despite multiple direct hits from 9mm, 10mm, .44 Magnum, .450 Bushmaster, and 12 gauge slugs, the lock's shackle remained secured, demonstrating its robust construction. Even after significant damage, including a blown-out keyhole mechanism, the lock did not yield.

Frequently Asked Questions

Can a 9mm bullet break a hardened steel lock?

In this test, a 9mm round hit the edge of the hardened steel lock and bounced off without causing any damage or opening the lock. Subsequent tests with larger calibers also failed to breach the lock's integrity.

What happens when a .44 Magnum is fired at a hardened steel lock?

A .44 Magnum round impacted the shackle of the hardened steel lock, breaking the zip tie holding the chain. However, the lock itself remained functional and intact, showing significant resistance to the powerful handgun round.

Which firearm caliber was most effective against the hardened steel lock?

While no caliber fully opened the lock, the .450 Bushmaster rifle rounds caused the most significant damage. One shot created a large crater, and a subsequent shot ejected the entire keyhole mechanism, though the shackle remained secured.
