mostly it was to see if my hunch was right about how it worked. Odd about the rule involving 12j, you would think it would apply only to explosives that are their own chemical, example Nitro glycerine PETN,or RDX. A binary explosive with a brand name would be tougher to identify without documentation in regards to spills or accidental ingestion. any how, don't matter to me gubberment wrote the laws we just have to follow them lol.
