Questions 1 through 9 remain "What is the wall thickness at the area of the bulges?" and without that information no one can provide rational advice Red...but we are likely to do so anyway

This "pimple" on the outside



Looked like this on the inside



and may have been caused by the pilot while reaming the barrels.

Possibly your nearest barrel expert?

Thanks Dr. Drew. BWT forthcoming in a day or two. We recently moved, and it's still in storage. Mine is the type that you have to mount to a wall to get an accurate reading.

At the risk of opening a hornet's nest, in response to the OP's question those Perazzi bbls. might lend themselves to becoming a 'carrier barrel' for a set of tubes or even being chamber sleeved in the case of the affected barrel.

W/o seeing it and doing a bit of measuring one can't honestly evaluate it's 'salvageability' or 'repurposing' for either application/remedy. I do know of guns treated in both manners that continue to provide good service target shooting. Just saying its worth having a party who does such work evaluate it and go from there.

As to bulges removed from the chamber area, I have a 28ga. O/U that came back from a loan for someone to shoot dove w/in the late 60's that somehow got a bulge in it's lower bbl. roughly 6" back from the muzzle & in front of the forearm. The side ribs were not loosened. I have shot it that way since and still do and the gun has digested hundreds, if not a couple of thousand or more rounds since usually through that same bottom bbl. being fired first. Does it bother me? Of course, if I think about it and that it happened. It wasn't intentional, I know that. Am I concerned from a safety perspective? Not in the least. It's a 26" IM/F Charles Daly Superior grade Miroku and its still a delight to shoot dove with. Value was degraded, not the utility. 'Nuff said.

Very interesting discussion. I concur in that I would not want to mess with a bulge close to the chamber.
As to a bulge closer to the muzzle, after inspection with a knowledgeable person I would not be afraid. I had such a shotgun with twist barrels that had a bulge and a split about 5 inches from the muzzle on the bottom of the left barrel. With the concurrence of an individual with far more experience than I the the bulge was beaten down on a mandrel. I then took the barrelset to a local welder who told me to machine a piece of copper to fit snugly under the weld. He welded it and after dressing the weld I use the gun as my clays gun without a problem.
My point 1. The bulge was close to the muzzle and 2. I had a knowledgeable person look at it.
