No, I'm not plotting a robbery or anything... well, sort of, but it's for a story. I'm wondering what type of bullet would be used to penetrate bullet-resistant glass because I'm planning a scene where two enforcers ambush a police convoy to bust out a safe cracker and I remembered back to the scene in an episode of Burn Notice where Mike said something along the lines of "the right kind of bullet can penetrate any glass, that's why they call it bullet-resistant glass." Then Mike's buddy in the episode popped out of a van and started pumping rounds through the windshield of an armored SUV with an M4.

Is there any truth to this or is it hogwash made up by the show's writers? If the former is true, what type of round would be used in the situation and will it chamber in a standard military 5.56 bore?
