Shortening 30” bbl’s 2 inches

[Brush Buster]

Since the bulge is that close to the end of the muzzles ,I don't believe the bulge is a big deal really ,I think If it were mine I would just let it original and not worry about it ! Of course just my opinion , it is yours so its up to you !

Depending on the severity (height deviation from surrounding surface) Bulges can be tapped back down, against a mandrel. If chamber bulges can be tapped down, with thick walls, thinner walls further up the barrel shouldn't be difficult. Consultation with John Hosford or Breck Gorman would be a good starting point. That would be my route before I opted for something else, which will certainly impact the value as much as 50%.
