Articap, I meant making BP from scratch, it would be wet then dried and sifted. I think I said I wouldn't wet Goex ffg. Sifting would be cool but not grinding it.(Goex)
And George whatever my friend, I have set BP off with ESD and current, so whatever you think or want to do with your BP is fine by me. Only I won't tell anyone else that what I do is what they should do... and that's was the only reason I continued this post again as long as I have.
Now I can say I'm done...it was fun as usual...
...and for those who can't buy the powder they need here you go...
Recipe is from a friend.

•Initial setup supplies•
*1: a 3lb Rock tumbler ( ball mill )
www.harborfreight.com -approx.$25
*2: Digital scale to .1g accuracy
www.digiweighusa.com - approx.$20
*3: 100 .457 or larger lead balls
*4: Good airtight containers to mix/store
*5: Stainless kitchen seives or screens to approx. grain size
••Chemicals-
@
www.firefox-fx.com( cheapest I've found, great service!, bulk discounts)
*1: Potassium nitrate(KNO3)- 10 lbs for $34.50, enough for 13.5 lbs of BP
*2: Charcoal,(air float)- $3.75/lb
*3: Sulfur- $2.50/lb
*4: Dextrin-$2.80/lb
•Industry Standard BP Formula= 75% KNO3 15% Charcoal 10% Sulfur
* Many people make there own charcoal from Willow, it's considered to be the best for fast BP. Airfloat worked fine for me!
•••Directions-( Best to do all of this outside of course!) Use some common sense and it will be a safe project.
1- Set up the ball mill with a 50-100' cord, away from people and buildings, on a solid table or ground. Remotely turn the ball mill on/off. Just an extra safety measure! - Put the 100 lead balls into the barrel of the tumbler.
2- For a 200g batch,(little under 1/2 lb) weigh 150g KNO3, 30g Charcoal, 20g Sulfur. Pour into tumbler barrel and place back into tumbler.
3- Mill for at least 3 hrs. Remotely shut tumbler off.
4- Pour tumbler contents through screen over newspaper, to seperate meal powder from lead balls.
5-Once you have the desired amount of meal, put it into large sealable container ( lock&lock from Wal-mart is great, they have a silicone seal and snap lids). Add an additional 8-10% Dextrin( 200g meal gets about 20 g dextrin)
6- Shake to mix then add small amount of water( spray bottle works best). Shake again. You want the powder to clump but not be too wet. You can always add more water and it's helpful to have some extra dry meal set aside incase you add too much water.
7- Now take the "dough" and place it in the seive to be granulated. Use your hands or a spoon to force it through, onto a newspaper. (This is called "ricing" the powder. Commercial powder is hydraulically pressed into bricks, dried, crushed, seived and graphite coated. Pressing is easy if you have the press and can make the proper container to do this.)
8- Let dry in sun, 2-4 hrs.
9- Store in Lock&Lock container or empty BP or Pyrodex containers.
•Initially while not a big money saver, it's fun, easy and will save money in the long run!
