Sorry cybersniper

We would have to know EXACTLY what is lodged in the barrel to help remove it. We have no lights or tools at our disposal here.

I suggest your friend soak the bore with water -- close the hammer onto a tire valve cap over the nipple -- encase the rifle and take it to a gunsmith. Don't take any chances... especially metal to metal screw-in if powder & bullet may be present. Better safe than sorry.. it won't cost much to have the clog removed.
