Masterlock vs Different Caliber Bullets
This video tests the durability of a Master Lock against various firearm calibers, starting with a .22 LR which had no effect. A 9mm Luger caused a dent and moved internal plates. A .357 Magnum loosened the lock significantly, dislodging bolts. A 12 gauge slug and a 7.62x39mm round were then used, with the latter disintegrating the lock.
