M203 Propelling Charge Residue Investigation. Part I

Abstract

The M203E1 propelling charge was observed to produce residue consisting of large pieces of uncombusted bag, liner, and jacket material. This residue was produced when the charges were conditioned at 63 C (145 F) and fired in hot gun tubes. Subsequent testing showed that the problem existed with the M203 charges as well. A root cause analysis procedure identified causes and determined a suitable fix. Laboratory investigations of component materials and test firings of both propellant and component material variations were performed. Substitution of a higher melting point wax (Indramic 170C) in the wear reducing additive was concluded to be the only suitable solution to the problem. Details of all test programs, procedures, and results are included.
