Carlos,
Each ammo can carried 2000 rounds that were linked using frangabile links. When the ammo was loaded, the ammo went in the drum and the links broke apart and went into an empty ammo can for re-use. There was a chute on the opposite of the gun that the brass went down, when the guns were firing, and into another empty ammo can. We spent a lot of time dragging ammo cans! Along with the brass, there were always several live rounds that would go in the can that the gun would clear when it was stopping. Someone on the ground would go through the ammo cans and pull out the live rounds for re-use, the brass was shipped out and melted down I guess. We carried 18,000 rounds, plus several more thousand we would "sneak aboard" if going to a hot target or TIC. TO weight was 29,500 lbs. The guns could fire 3000 or 6000 rounds a minute. It was very rare we ever put 3 guns on fast fire, usually 1 gun on fast fire and the other two on slow fire. It was pretty impressive when we did put all three guns on fast, I have a great picture of them firing that I took leaning out the door. Also carried 40 flares, 20 in the forward flare box and 20 in the box by the door. We flew a lot of alert flights and the pilots would get bored and let some on the crew fly the "racetrack". I got about 200 hrs flying in the right seat, mostly making left turns!. Some pilots would, some wouldn't. I was lucky, my A/C liked me and the co-pilot HATED flying C-47's, so I got a lot of oppourtunities to fly. He used to say that the
T-38 stalled out faster than this piece of s**t could fly. He was probably right!
