A burn rate is used to define the lower limit of flammable solid in
the CFR, ie some number of inches per second, but the CFR doesn't
give a burn rate definition for explosives.  I don't have a copy handy,
but the wording is something along the line of "presents a deflagration
hazard."  (Class A explosives, of course, present a detonation hazard.)

The wording was sufficently vague as to encompress wadded-up newspaper
used as packing material as a "explosive".  It would definitely qualify
as a "flammable solid".

BTW, I typed up my "low explosives user permit" application today.  Connie
in the Cincinnati BATF office was quite helpful Friday when I spoke with
her.  Here's the gist of what I learned from her:

1)	You can just put n/a in any field relating to business practices,
	assuming you're getting a permit for personal use.

2)	Unless you're planning on storing either class B disposables or
	54mm reloads, in the blank relating to storage facilites say that
	you will not be storing explosives and that you will purchase
	them at the location where they will be used.

	(I don't suggest planning on storing the bigger stuff unless you've
	got $600-700 to spend on a magazine and a spot 75' away from anything
	to locate it.)

3)	Attach a note describing exactly what we do with the material (eg
	buy it at launches, stick them in rockets, and fly the rockets.)

Per Ross, the formal nomenclature for the stuff we use is:

	"Class 1.3C Rocket motors (UN 0186)"	(class B disp and 
						_assembled_ reloads)

and

	"Class 1.3C Cartridges, Power Device (UN 0275)"

		(54 and 98 mm reload kits).
