EXPLAINED: Why Imperial Stormtroopers Miss So Much. “Adam Savage of MythBusters fame decided to try and figure out just how fast the… whatever it is coming out of the blasters actually moves. Using the height Harrison Ford and the width of a door as visual references, Savage performs some arithmetic to come up with a shockingly slow speed: 130 miles per hour over 40 feet. For comparison, your average bullet comes out of the barrel moving at around 1,700 miles per hour. Stormtroopers may be better served by ditching the blasters for a good semi-auto.”
