I messed up. I was making some .44 shotshells a few days before Christmas and left Bullseye powder in my RCBS Chargemaster. We had some real odd weather the few days before, during and after Christmas where it was 75 degrees and we got 5 inches of rain. The humidity level in my shed, which is on a concrete slab, was so high I had the window unit pumping in cold AC just to knock down the condensation on things. That powder stuck to the green plastic hopper in the chargemaster and I mean really stuck. I can hardly scrape it off with metal. I'm pretty sure this type of thing would not be covered under warranty. I can't be the first person to do this but I searched the forums and can't find a way to free it up. I'm sure it still works, but I only feel comfortable using Bullseye in it now for fear of any stuck pieces coming off if I were using a different powder. Any helpful advice is appreciated.
