If I recall the 330 assembly correctly, it should be possible to destroy only the shackle (and perhaps some limited damage to part of the lock body) and still be able to remove and decode the core. This being the open forum however, I can't post exact details of how. This attack would require a good deal of machining skill and probably at least a quality milling machine.
Of course, even if the method I'm thinking of is carried out successfully, decoding and then cutting a key is non trivial.
