Hello guys,
I have a problem with my black powder. I want to use it as a lift for my small mortars but it doesn't burn anough fast. Then, I ballmilled it 9 hours so it burned faster but I'm still unable to lift a simple empty tube to more than 2 feet. I saw many place where they say to put some lift black powder but even my powder can't lift something. I'm using 0.48'' lead balls for ball milling with good grade chemicals. I use my own charcoal from hard wood. The only way I can obtain an ?explosion? (if we can call that like this) is by putting the BP in a small paper bag.
Help please
Thank You

I think there is already a BP thread that may have other hints and is a better place to ask this question.

However, are you granulating the BP? Say by making pulverone, or by pressing and corning?

How fast does it burn loose?

How are you making your charcoal?
Also, your tube your launching from IS capped at the bottom end and has no gaps between the tube and the motar for the gases to escape?
Are you using bp grains or meal powder?
