    So, lately i have been wondering about powder related stuff, and i started to think about black powder/synthetic BP like stuff. I was wondering if anyone knows how companies like Pyrodex make their BP into blocks...? And keep it burning somewhat similar to the granular stuff? Do they use some sort of highly flamable glue?

    Just curious, and thanks,

    I've heard it compared more to the model rocket engines from Estes than black powder, and supposedly they leave behind as much as 50% of their weight in unburned "stuff", whatever that stuff is so there must be some inert glue holding them together.

    i shot pyrodex 30 grain pellets for the first time and last time yesterday. first 6 shoots were fine. loaded the cyl up again and three out of six didnt go off. so i put new caps on. and one went off but it was a bad hang fire. when it came time to clean i pulled the remaining 2 balls out. and i noticed how sticky the the fowling was. nasty crap.ill stick to powder.

    Why would they use intert glue, instead of a burning stuff? I would not want the unburnt crap in my barrel...!
    Thanks for the replies.

    It's not glue, just the nature of black-powder and black-powder-substitute combustion. The combustion products are 50% gas and 50% solids (finely dispersed solids accounting for all the smoke).

    From the excellent article TexasRifleman posted:

    So, they do use a burning "glue" or whatever? But then there is this quote from the artical:
    Maybe they just press it? Hmm...intresting.

    Thanks for the link TexasRifleman, very informative.

    more than likely they wont use binder, except maybe water.
    but I bet it is just compressed.
