Saw some neat guns today

[Rocky Raab]

You're right: the Vulcan doesn't sound like a gun at all. The shots are too close togther to sound like "bang bang bang bang"

It's more of a "Brauauauauauauauauauauaup" sound. And you are right about those empties! More like a firehose spitting brass.

I've been right between two of them firing out the side of an AC-130 gunship. Awesome.

It's even more awesome (and awful) on the other end. You do not hear the muzzle blast at all. The ground suddenly acts like it's erupting in flame, white-hot sparks and a strange ripping sound. Truly it's like the earth itself vomiting fire. And when that stops, you hear a faroff and ghostly "oooooooooooop" grunt that is the muzzle blast finally reaching you. But that sounds like the moan of hell itself coming from the pitch-black sky. It makes your very bones go to jelly to hear it.
