You should try fire-lapping.
Fire-lapping to see if you could dress off the bulge. Soft lead bullets at bore diameter impregnated with lapping compound fired at air gun velocity will knock the high spots off remarkably quickly.
These bulges are common under sight dovetails or when the barrel is over tightened and squeezes down at the throat and lapping will correct it in a few shots.
Fire-lapping may solve your problem without any muss or fuss.
