Heres brushhippys recpe for anyone who wants it
there are also links for the ingredients.
you can get a ball mill from harbor freight tools.
here is the recipe for brushhippies Mighty Magical Muzzleloading mix...
Mix together:
75% = 150 grams
KNO315% = 30 Grams
charcoal10% = 20Grams
sulfurTumble/grind for a minimum of 6 hours or longer.
After tumbling/grinding the mixture for atleast 6 hours add the binder/dexterin (AKA corn starch). Add 5% of the total weight of the powder mixture recipe which this recipe is a total weight of 200 grams so this recipe will require 10 grams of dexterin to be added to the mix then grind/tumble for an additional twenty minutes.
How to make Dexterin:
get a cookie sheet and spread the corn starch evenly across the cookie sheet and Bake in the oven at 400F for three hours.
after all four ingredients are all mixed together empty the tumbling container on a screen with a tray with news papers underneath to catch the powder
(do not breathe in any dust!) and sift the powder to separate the lead balls, replace the balls in the tumbling container.
once the powder is separated dump your powder onto the tray, use a credit card or bondo spreader to evenly mix in water to the consistency of damp sand so that it can be balled up into pucks.
but not so damp that when you squeeze it into a puck that you don't squeeze water out.
once the powder has reached the right consistency grab a hand full of the mix and squeeze it into a puck and rub it through the screen evenly on the tray
(#16 screen makes FFFgranuals), do the whole batch then allow the water to evaporate.
a tip to help the powder dry faster
before screening the powder place news papers over the tray this will help absorb the water out of the powder grains.
you now have a batch of brush hippies mighty magical muzzleloading mix
EDIT: to make your screen measure the outside dimensions of your tray then cut 4 pieces of 3/4"X4" lumber accordingly you will want to make the lumber slightly larger so that it will fit over the tray. on two of the parallel pieces you will need to add 1 1/2" to the total length of the wood in order to nail the pieces together. then start by stapling one side of the screen to the wood frame pulling it snug as you staple then pull the other side snug and staple then staple the other two ends tightly.
