I had a trojan with a bulge in a similar spot. I ended up finding some barrels that fit but my plan b was getting some 20 or 28 gauge inserts which would allow it to be a shooter. If you go the pound out the bulge route Im wondering if you would have confidence in the barrel repair since that is pretty close to fingers and face. Im not a gunsmith but I have a physics background since the barrel diameter is greater at the buldge the pressue against the buldged barrel wall is lower since pressure = Force/unit area. You restore the barrel to its original diameter the shot pressure agains the barrel wall at the repair would increase (less barrel area same force) but the stressed metal would seem to be the same at the repair. In other words it seems to me that if it was unsafe to shoot in the bulged condition it would be less safe to shoot after it was repaired unless there is some change in the metal that occurs post repair .
