Browning Lightning with Bulge in barrel

[Pappabear]

I have a friend that has an O/U Browning Lightning, Belgium made shotty. Very old Grandfathers gun that reloaded and must have made a shell with no powder or whatever and the wad got stuck. Not knowing he then proceeded to shoot another shell resulting in a bulge in the Under barrel.

Is this gun safe to shoot, there are no obstructions?
The bulge is small, will attempt to a post a pic.
Can it be repaired, if so how/who/how much?
What would you do?

Any feedback to any of the questions is greatly appreciated.
