    Never had any prob getting KNO3. Or sulfur. Any charcoal will work. I ground some gourmet bbq charcoal once. (For an unrelated enterprise of course)
    Ball mill with a few fistfulls of lead sinkers in, so I read. Pulverises the ingredients together. Comes out 3-4F grade. If you want larger then you can get it wet, then dry, and screen.

    I'm a tree farmer
    So have all sorts of wood available for the charcoal

    Willow
    Acacia
    Hazel
    Walnut
    Euc
    Leyland
    Macro
    Lusitanica
    Lots of natives

    So small lots of different charcoal could be tried to find what works best

    Guy in the OP link did it for you. Willow.

    My method is a metal 20lt pail. packed with kindling, hole punched in lid. Chuck it on coals of hot fire. The hole will flare (methane and wood alcohol vapour, i think). When it stops flaring, rake it out, bung the hole with clay and let cool.

    Traditionally done by starting big fire of felled trees, a matter of judgement, when to bury it in soil and let it burn out.

    a coffee tin with hole in lid on the BBQ works too.....takes some time ,but its worth it in the end...the head off a sledgehammer and an old meatdish NOT MUMS GOOD ONE....and a couple of hours rolling the lumps down to fine grit works...so Im told.

    Sorry not a member of research gate.

    Find a copy of “Life in the Gorge” by Les Marriott. He talks about making his own gunpowder in the depression and the resulting exploits.

    Maybe you should speak to my mate. Hes a real enthusiast and has it pretty well sorted. Gets results equal to and better than commercially available stuff, and shoots quite a lot

    Not smokeless, used green pussie Willow, peeled,paint tin with 2 small holes,cooked in a fire till gas stops burning, cover the holes and let it cool.
    There's your charcoal. I ground it through a cast iron mincer then a gem tumbler with 50 cal round balls for about 4 hours.
    Added some other ingredients, tumbled again at the full length of my longest extention cord,now you have "gunmeal"add 5% dexrin,dampen slightly and push it through fly screen mesh.let it dry on newspaper.
    Quite fast and clean.
    Real guns start with the number 3 or bigger and make two holes, one in and one out." -

    I always thought the grains of the stuff you buy are very hard so at the damp stage it could be compressed into round pucks, then dried and then granulated, should give you nice hard grains with more oomp. I have found my case cleaner also is good for removing the spruce off my lead round balls, a ball mill!!!, nar. Have made a puck maker that fits in my reloading press, just for fun and giggles only you know.

    Good point!

    I'm dramatically out of my depth in that I haven't done it myself, but have read about compressing BP to get the an accepted standardized density so that true BP (Not substitutes) is equal for both weight and volume at whatever that given density is, which I thinnnnnnnnnk came about because traditionally volumetric powder measures are far more practical, affordable, and robust in day to day life when people were using BP guns for feeding themselves or fighting. There may also be a benefit that hard BP grains don't disintegrate over time from shaking until they end up as FFFFg dust.

    Also have a vague memory of black powder grain burn rates decreasing as density increased(??I may be wrong??), which could explain why people making their own are getting faster, fluffier powders at the same gravimetric weight than the denser commercial manufacturers.

    Two neat pages relating to density vs weight
    BP Conversion Sheet (revised December 2012) - would have been neat to see a 5 or 10 shot median velocity with same projectile/firearm with each load/powder

    https://www.chuckhawks.com/blackpowder_volumetric.htm


    I'm curious if one were to make smokeless(sulphurless) black powder, whether it would behave similarly at the standardized black powder compressed volumetric/gravimetric grain weight..... probably not, but would be neat to find out, and would certainly make measuring it with the normal BP volumetric scales easier.

    There are no smokeless black powders the smoke cloud is solid potassium salts caused by the reaction of the nitrate with the sulphur and charcoal. Potassium carbonate, sulphate, and sulphide which gives the rotton eggs smell.
    The gasses are colourless. Reducing or removing the sulphur might reduce the smoke in humid air as sulphur dioxide reacts with water to form sulphurous acid, the droplets of which are white.
    This has really got me thinking about going back to making my own.

    Ok so I read all that and now my head hurts !
    Can you get coronavirus from thinking too much ?
