Claim 6:
7. The projectile of claim 5, wherein the projectile is operative to:
receive expanding propellant gas through the gas inlet;
responsive to pneumatic force provided by expanding propellant gas, release the rotor from the rearward position;
responsive to pneumatic force provided by the received expanding propellant gas, move the released rotor forward along the axis in the interior space;
emit gas through the gas outlet as the released rotor moves forward along the interior space; and
progressively block said emission of gas through the gas outlet as the forward surface of the rotor approaches the internal surface of the member, thereby progressively braking said forward movement of the rotor and progressively increasing gas pressure between the forward surface of the rotor and the internal surface of the member.
