Lead styphnate been working steadily for a hundred years. KDNP looks promising but y'all go on up ahead with it and I'll be along sometime.
"Pacific Scientific Energetic Materials Company (PacSci EMC) in Chandler, AZ, in conjunction with chemists at NSWC-IH, has been involved since 1999 in a program to develop existing or new materials which would serve as a drop-in replacement for LS and which incorporate no toxic or environmentally undesirable elements. We investigated a wide variety of chemically distinct materials in order to find a green replacement for LS with suitable sensitivity and output characteristics and selected 4,6-dinitro-7-hydroxy benzofuroxan, potassium salt (KDNP). KDNP completed 8020.5C evaluation testing in 2007 and, based on the results (NSWC Contract #N00174-06-C-0079), Naval Sea Systems Command qualified KDNP as a primary explosive in accordance with the requirements of NAVSEAINST 8020.5C and identified it as a safe and suitable for service use, and qualified for weapons development."
