    Good info on the 808. I did not know what it represented. On this side of the pond we call "gelignite", "blasting powder" or sometimes "blasting gelatin". I don't think I have ever seen any production US shells loaded with it (but would be very interested if anyone has samples). It is the same composition as double base gunpowder.

    I have not been a chemist in a long time but neither of these should give you a signifiicant amont of HCN generated from combustion. A lot of synthetic polymers do liberate HCN if burned. I mention this because I did not know if any PIAT rounds had synthetic liners etc. as a source of HCN.

    Ade, if you can find out more from your Dutch friend it would be interesting.

    Spotter, We were taught that some of the British shells from WWI had picric acid (2,4,6 trinitro phenol) both as a propellant and as an explosive. I have never seen any. Have you ever seen any and if so how are they marked.
    Im not that sure about different explosive compositions but i believe Picric acid was used as an explosive and was later re named or developed into the more commonly known Lydite,,Im sure ive also heard of a lot of old ordnance becoming unstable/sensitive due to the Picric acid crystalising..sorry cnt provide a definitive answer but may give you some leeds for further research..spotter

    Thanks Spotter. Lyddite is made of Picric acid and TNB (trinoitrobenzine) I think. I have not thought about this in a long time. One of my instuctors said in WWI the Brits used picric acic as the propellant, explosive and then as an antiseptc. He also told us the metal salts of picrate are somthing very sensitive and something to be feared. We made picric acid in a class but after I pointed out the potential they removed it from the lab. No worse than making TNT or some other high explosive just keep the lead vessle cold, very cold.

    I think I'll pull out some of the old books.

    Thanks Ade Let us know what you find out.

    Bill that is nice. Are you holding it for me for Christmas?

    That will do Uncle Bill. Now that spotter showed me the sub cal trainers and they look easier to make I need to find a tray for it. Naw I think I'll still plan to build at least one full size one to shoot.
