Porous propellant composition for caseless charges is improved by compressing the composition to an average pressure of at least 1,000 psi. The invention also includes the improved propellant charges.
A method of preparing a unitary caseless propellant charge, comprising forming an integral mass of propellant composition containing particles of a removable filler, leaching out the filler particles to produce voids in the composition and to form an integral dry mass of porous propellant composition, compressing said integral porous mass to an average pressure of at least 1,000 psi to reduce the volume of the mass at least 20% thereby rendering the resulting charge more brittle and firable so that it disintegrates to a greater extent when subjected to s...
