Noway,
Thanks for the advice, it all souunds good. I just wondered if anybody else ever had this happen. I am very happy with this rifle, especially since it only cost 300 bucks, new!
I am going to try putting pressure under the barrel at the forearm tip. All I have to lose is the time and three shots or so. You never know, it might cause the rifle to shoot one ragged hole

(I wish) One trick that I' d like to try is one with hot glue. A gunsmith told me about it. Instead of stuffing paper between barrel and stock, he said that hot glue works well, because it fills the area perfectly. Any extra glue just oozes out and can be trimmed away with razor blade. If it doesn' t help, then just peel the glue out, causes no harm.
