Take it a apart and give it a good cleaning and lube. Check out the gears too carefully. I had an MP5 hicap jam on me, did exactly as you outlined, would wind fine but not shove BBs up the tube and put pressure on them. I did as I suggested above, and found a single grain of sand stuck between the teeth of the middle gear. I popped it out, lubed and reassembled, worked perfectly.
