Rem 1100 stock loose

[Pileatus]

I was shooting skeet this afternoon, and after firing a shot, I noticed that the stock had come loose on my 1100. It was moving a bit from side to side, so I figured the stock bolt had come loose. Long story short, I removed the butt plate, made sure all the washers were where they needed to be, and had three guys tighten down the bolt as hard as they could without breaking something, and the stock was still wobbling. I didn't see anything broken when I looked the gun over, but I'm convinced that something, somewhere, has failed because I noticed the stock wobble immediately after I pulled the trigger, and not a moment before, and I had been shooting for at least an hour. Is there something I'm missing here? I don't know if this is a common problem, or if I should have the gunsmith look at it, but I'm out of ideas. Shimming the bolt up with some more washers would probably, work, if they made 5/8'' flat washers that weren't 1.5 inches in diameter.

Thanks in advance!

Make sure the action spring tube is fully screwed into the receiver with a little blue LocTite.. You probably ran out of threads on the other end.
