I think the Ramset videos might count as 'cheating' - there probably aren't many locks designed to take the force of a .22 blank powder charge to the body and survive. And the ones about shooting locks with a 50 cal rifle definitely count ;) Still really interesting to see the limits of lock endurance nevertheless - really underscores the idea that no lock is undefeatable, it's just about how far somebody is willing to go to defeat it.
