"DANGER , WILL ROBINSON!" (Remember that classic line?)
It strikes me that some of the formulations mentioned so far in this thread have a frightening similarity to compositions that Tenney Davis speaks of on pages 360-366 of his classic text. Cheddite 60B in particular, has a detonation velocity estimated at 2774-2843 meters/second when encased in paper, or about 1/2 that of solid TNT.
Some rocketry enthusiast are aware of this fact, while others are not. Anyone experimenting with composite oxidizer/hrdrocarbon mixtures should be aware of the high explosive risk associated with such propellents, since the possibility of unexpected detonation is a very real hazard.
For obvious reasons I have not posted the components of the more common Cheddite compositions, but some closely approximate compositions already discussed in this thread. For anyone experimenting with such mixtures, a close reading of Davis is both a required and reasonable exercise in safety, since a high order detonation "would be bad" (see "Ghostbusters" for an explanation of precisely what "would be bad" signifies).
Stay safe, and kindest regards. Harry C.
