Yep been shooting forever and m/l for over 20 years and this is a first for me. I must add that we have had many moths around this year more than usual. I had the gun stored vertically for the record. When I first pulled out the plug I though it was a patch that fell to the ground then the other stuff fell out and I looked through it and found the moth/wings web and other crap. I guess me running the patch down the bore forced all the debrie into the breech face.
