Anyone used it before? It apparently hasn't been in wide use since WWI, but it's very easy to make (85:15 ammonium nitrate to charcoal) and appears to be superior to black powder (no flash, no smoke, no residue, similar ballistic properties) though it has a few significant downsides.
1. it absorbs moisture from the air
2. the crystal structure breaks down at around 30°c, making the compound finer, leading to a more rapid decomposition (burst barrels)
both of which can probably be mitigated by using thick, sealed casings or cartridges.
