The questions I worry about is where is the bulge and what caused it? If past my left hand, well down the barrel I'd try to get it tapped back in and roll the dice. If near the chamber to as far as my left hand I'd scrap the barrels. Second failure could result in serious injury to others or me. I just won't take that chance anymore.

I've seen both steel and Damascus barrels that had bulges removed. Was told it was just a crap shoot if they would come back. Metal men tell me worked metal should be stronger but who knows. I do remember Toni had a 20 bore Clark which had a bulge removed and then pass reproof. Only to fail n the first box Os shells. You pay your money and take your chances. Just keep the risk down as much as you can.
