I've made pounds and pounds of BP but this is the first time I was dismayed. My KCLO3 was prilled. This worked fine when I ran it through a coffee grinder and once ball milled it. This time I ball milled it and it came out feeling damp. I added more balls and let it run for some 30 hours. It still had a bit of a gritty feeling. I keep my float charcoal in an air tight container. After screening the stuff it never came to the same hardness as all other batches. Usually my stuff is screened - some call corning - for cannon application and is extremely hard. This time you can grab a handful and crush it into powder? I think my KCLO3 might have been damp? I only made 2# of the stuff and still have about 5# in a jar. Now what? Do you think I could put it into solution, dry it and re-mill? Or....?
