The problem with bulges is that it requires much peening to bring the metal back into place. This peening is more than likely to pop the rib solder joints loose. I have sworn off trying to repair ring bulges because of this. However, a minor bulge, as mentioned by Bill, I might try again. In the case of a ring bulge you cannot get the part of the bulge that is under the ribs anyway, without removing the ribs and relaying them. Now, you're really getting into an expensive repair. Better be some valuable barrels.
