I will try another small batch with willow charcoal and corn it differently.
Not just any willow. Black willow.
(Weeping willow) is not a preferred ingredient in the making of homemade B/P.
Corn powder:
Raw Meal powder that is Spray Dampened lightly with distilled water then compressed in a {piston type of mold} with Hydraulic pressure applied. Thus creating a disk shaped form of tightly compressed powder.
Disk is then removed from its mold and allowed to dry. Once fully dried. Disk is then broken into smaller pieces, sieved to size thru screen/s approximate in size to >F-size kernels.
Left over powder not meeting the F-size wanting is simply recycled.
Corn powder is best used in B/P handguns.
Corn powder Plus's? _ It seldom settles beyond the point it was originally rammed too. (A necessary requirement for B/P pistol use.)
Corn_ Is alot less barrel fouling than Screen Powder.
Corn powder is a Universal powder. Can be used in B/P pistols or long barrel B/P firearms.
Corn it's Negatives? More laborious to make. Requires more tools to make.
Simple Screen powder on the other hand:
Is raw Meal powder: that is spay dampened lightly with distilled water and hand formed into a lightly moistened Ball.
By hand the Ball is forced thru a screen approximate in size to the F-size wanting. Those screened powder kernels are captured below its screen on a flat tray surface and allowed to dry.
Screen B/Powder is Primarily used in B/P long barrel firearm applications.
It's Negatives:
Screen powder will settle some in level height after being rammed and is more barrel fouling than Corn powder. Not as versatile in use as corn powder is.
Screen powder Plus's?
A shade Easier to ignite than Corn powder. Quite often faster burning than Corn powder is.
