You know Ron, it wouldn't hurt to call TC and ask to speak to one of their technicians (not a customer service clerk) and explain the situation. You never know, they might have a barrel sitting around and would be willing to switch your action to a new barrel.

Also, you could ask about the safety issue. But given the liability issue, I would expect them to tell you not to shoot it. As for me, I would not be concerned. I believe there are a LOT of guns out there with slightly bulged barrels being shot all the time with the owner not even realizing the barrel has been bulged.
