Would a stuck wadding cause it to blow up?
I wouldnt want to find out! I know of a few stories of people getting mud in the barrel which caused it to split, swell, or rupture. There is no way mud in the end would cause as much damage as this may have. I almost could not knock it out with the stick I used to clear it. Its was sure tight. I'm no engineer well versed in pressure but I believe there would have been an "unplanned rapid disassembly".
