Thanks, I have found all this to be true I think the commercial stuff is the way to go. I am almost ready to give up. Sure is fun though. Going to try some of the suggested powders. Need to get some accuracy on my Patriot Pistol and will send out the solutions when I find them. GilMaking your own, and I have, falls into that class of things that are nice to know how to do but really not worth the trouble. Aside from the safety aspects - which are very real - you will not end up with a finished product that is anywhere nearly as effective as the commercial stuff.
By the time you buy a ball mill and quality chemicals (and I made my own charcoal), you aren't saving money either.
