Five detonation tests were conducted on each of the 4 types of cartridges to determine if a detonation would occur and if so, would the detonation propagate from cartridge to cartridge. One cartridge in a shipping container cardboard box was primed with 30 grains of tetryl and initiated with an Engineer Special blasting cap. Each type of cartridge was also subject to a cook-off test. No detonations occurred in any of the tests. The MC-1 and MC-2 primed cartridges were ruptured and threw burning propellant within a 10-ft radius. The remains of the cartridge cases also remained in this area. HE MXU-4A cartridges did not ignite as the primer charge could not be placed on the propellant grain. All of the cartridges cooked-off between 10 and 15 min after the scrap lumber was ignited. It was concluded that all of the cartridges tested were quantity distance class 2, storage compatibility group J and ICC shipping class C.
