Oh I'm well aware of the inconsistencies of the gyrojet. Hence, the

What happened to the burning propellant while you stopped the rocket with your finger? That might get a bit warm, no?

Um, do we have any Paul Bunyan types out there willing to test a shoulder-fired 30mm GAU-8 single-shot?

I'm rather surprised to see that the last serious ballistic work was done that long ago. Hey, did you know that the Bell X-1 sound barrier rocket plane back in '47 was supposedly designed after the .50 cal boat-tail bullet. They knew the BULLET broke the sound barrier, so they thought they'd scale it up and see if it'd work in a plane. I hope Yeager didn't ever see spent .50 slugs looked like at the range, or he might have reconsidered that little trip!
