I was cleaning my CVA Plainsman, and the jag popped off the end of my cleaning rod while wrapped in a piece of old t-shirt. Long story short, now I have a thick chunk of t-shirt and plastic severly crammed into the chamber end of my barrel, and can't get it out. I was able to use a cut down valve stem from an old tire, and screw it into the hole in the barrel where the gas from the nipple would flow in (I don't know the name of that hole, or the part that the nipple screws into) and used an air compressor on it, but to no avail. I was actually able to get up to ~70 psi. I've seen people mention putting a cap on and firing it to clear obstructions, but this is wedged pretty tight. I'm new to BP, and I'm nervous about doing that. does anyone have any tricks to get something like that out? Can one simply remove the breach plug?
