Not quite a rocket.  The key difference is that the propellant
(cartridge) remains in the barrel and is not carried by the round. This
means that acceleration is all within the barrel and the round is fully
ballistic once it leaves the barrel.

In a rocket or gyrojet situation, the propellent is carried by the round
and the round could continue to accelerate after it leaves the barrel.
There are several recoilless rifle designs where pretty much all the
propellant is burned within the rifle, but in a gyrojet type round I
would think that you would want a longer burn time for higher
velocities.

In other words, it releases propellant?
