I'm thinking 500 gr. of 1F and a couple cups of cremora.
If you are trying for the fireballs, you need an external source of fire for ignition. One would think the powder charge would do it but the combustion gases are starved of oxygen and likely won't ignite the cremora. At least that has been my experience.
