    Have seen the components ground up in a old vitamizer (spelling), the older version of these new smoothie makers, and then combined. Seemed to work OK..... was for a pack howitzer.....and it went bang.
    Please excuse spelling, as finger speed is sometimes behind brain spped........ Or maybe the other wayy.....

    Garden centre's are a good source of potassium nitrate (stump rotter) and flour of sulphur (organic fungicide) Flour of sulphur needs no grinding either but the nitrate does.

    There is a better way.... NOt that I know from personal experience.
    The stump rotter is sold in small jars for lots of dosh.
    Try a hydroponics store, should get a big sack for bugger all.

    Just make sure it is potassium nitrate, not sodium nitrate. Sodium nitrate is hydrophilic and makes your gunpowder moist just through being exposed to atmospheric humidity.

    A sackful... are you planning on powering your 40mm au natural?

    be interesting to see how you get on. I have noticed potassium nitrate disappearing from some of the traditional sources.

    Ask your local hunting/gun shop to get it in. It's also used for making sausages!
