I was thinking of the same thing, and it may already have some iron in the mixture, but the iron acts only as a catalyst.
The propellant mixture in solid rocket fuel such as used on the Shuttle SRB motor consists of an ammonium perchlorate (oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide (a catalyst, 0.4 percent), a polymer (a binder that holds the mixture together, 12.04 percent), and an epoxy curing agent (1.96 percent), which is extremely flammable.
In fact the Hindenburg burned so strongly because the skin was a mixture or iron oxide and a heavy dose of aluminum powder, not because of the hydrogen.
This bomb is effectively solid rocket propellant allowed to ignite all at once.
YEP!
A 'Home-School' version, as a Science Project, uses a 'Steel Wool' pad - unrolled - and lighted with a match/lighter.
Makes an impressive show - serves three.....
