I had the same problem shooting 16ga RST lite shells at the Vintage Cup last year. I had powder build up in the latch to the point I couldn't close the gun. I had to us my pocket knife to get the powder out before I could continue to shoot. The weather was nice, so I don't think it had anything to do with the powder not burning?
