The most recent example of a mini-gun I can think of is from Black hawk down. They were mounted on the sides of the the blackhawks. In the scene where the empty shell casings are raining down on the lead character. That's a mini-gun. Not sure about ammo size though. I'll ask my friends, they're ammo troops in the army.
But like others have said, impossible to actually use one without it being mounted. The recoil would send you flying.
