I took out a few hard drives to the range to shoot. I was shocked by just the dent I put on it with my .45. I was expecting to go right thru it. Those are a lot tougher than I thought. I can tell you that when I see someone shoot into the computer on tv or a movie, I know they did not damage crap. If you do get the chance to do it, I would suggest going out there and doing it. Fun to see how little damage you actually cause them.
