Actually, the GE M61/A1 20mm Vulcan fires 6000 rounds per minute... It was set up that way when used as a self-propelled air defense weapon was well.

One of the most impressive sights I ever experienced was watching a Vulcan pour fire into junk vehicles at Fort Bliss from a distance of about a mile and a half. Those 20 mm rounds are about 6" long, and even with every fifth round a tracer, it looked like a ray gun, solid red. The sound can only be compared to a double A fuel dragster at full throttle. It looked like someone was standing inside the vehicle heaving buckets of brass out as fast as they could. As the rounds they were shooting that night were HE, the effects on the junk vehicles were very impressive. What was left were pieces small enough to put in your pocket. All in the matter of a very few minutes.
