I've got a powderhorn I am working on and while cuting the base off square I noticed the inside of the horn had like a membrane skin that was a little loose so I tried to peel it all out. What was loose all around the inside of the base was tighter up inside. I tried a screwdriver going all around, tried twisting it with some needle nose pliers. Now I've got a big birdnest of it up in the neck that I can't figure how to get out. Any suggestions?
