Right on, Kevin!
Don't need to press pucks, screening will render good powder.
Milling is Important ... it's done with DRY*** powder, just a cheap rubber lined mill and some lead balls is all that takes and there is nothing that will kick off powder milled that way. If yer the least bit concerned (as I'll admit I was!) take the mill outside and run an extension cord to where the milling is done far from yer dwelling and do just a small 1/2 or 1/4 pound mix.
After milling, the powder is wet down with a bit of plain water (NO chance of ignition!) then pressed into a screen and left to fully dry. Done.
***DRY powder means that all three ingredients need to be as dry as possible. Potassium nitrate, charcoal, and sulfur are very hygroscopic and will pull in water from the air which will change the 75-15-10 mix ratio and the resulting powder will not be as efficient or strong. Using a food dehydrator for the ingredients will fix that issue.
