You said that the owner noticed the mid rib was loose not long after he purchased the gun and was told it was not a safety issue. I am wondering who told him that and I would have sent it back to the manufacturer right then........ Also, you said that it was caused by shooting a certain brand of shells that are known to have cocked wads. That part is bull. I have a brand new Remington Gun Club (on display), in my basement that has a cocked wad. I noticed it was cocked during a round of trap when it wouldn't go into my gun because the wad is pushed so badly out the side of the shell. One of the guys I shoot with had a AA with the wad cocked just a few weeks ago and couldn't get it into his gun far enough to get the gun to close. So, any manufacturer can produce a shell that has a cocked wad as far as I am concerned. Plus, I have NEVER had a cocked wad in all the thousands of rounds I have loaded over the past ten years. Just my opinion. Good luck.
