Level 10 Masterlock vs different caliber bullets
This video tests the ballistic resistance of a Level 10 Masterlock against various calibers. Surprisingly, even powerful rounds like 9mm, .45 ACP, and .44 Magnum only cause minor dents. A 5.56 green tip round significantly deforms the lock but doesn't penetrate, and a 12-gauge slug creates a large crater but leaves the lock functional and closed.
