My reloading room had gotten to be quite a mess, so I finally decided to do the big clean. It really bothered me to just vacuum up all that shot, so when I was finished I cut open the vacuum bag and poured the contents out into a container. After pulling out dog hair, stink bugs and 2 live primers (whew, glad THAT didn't cost me a vacuum), I have 2 lbs of shot, powder and dust. I was thinking about spreading it out on a fine metal screen and lighting it on fire to burn off the powder and, hopefully, the dust. Has anyone tried this? Or what about sticking a fan under the screen to blow the gun powder away? Any ideas?
