From: [EMAIL PROTECTED] The GyroJet took the idea for setting off the cartridge from a reverse of the old pin-fire rifles, IIRC. At about 5 dollars a shot, it was terribly inaccurate, and at the muzzle it had no real energy, thou was burning fiercely. Beyond a hundred yards, the propellant having burned out, the "bullet" was so light that it was quickly slowed by air resistance, and was so light it would be unlikely to do you any damage, either. Since accuratcy was said to be so bad you had trouble hitting a barn door at 20 yds, you can see why it died out quite quickly. The action of firing the "bullet" hit the cartridge on the nose, then the rocket pushed the hammer back down, ready for the next shot, as it left the chamber. Very weird. As for Caseless ammo and the G11, I thought the whole gun was sealed, so the caseless ammo was sealed into the mag, and the gun had no moving firing pin etc, so was also sealed away from the squaddies hands. All to stop the grains of sand. It was meant to be very good, but then, it was expensive, and I don't know how water-proof it was. Cleaning the barrel would be fun, after use, if it was all sealed! Or clearing a dud round. -- They spent loads on making sure that it was easy to clear a dud round, all you had to was rotate the cocking handle (the chamber rotated to pick up a round) and the dud would fall out a hole underneath the chamber.
