Why not tap it down and call it good.
Doesn't work that easily, at least not for me. You can't remove the bulge between the ribs, and by the time you have tapped the bulge outside the ribs down the ribs have popped loose. Removing bulges is wasted time, IMO.

I think, the more rare a gun, the more hoops that are worth jumping through to get it fixed as close to original as possible.
I was thinking that while cold working might technically increase the tensile strength of the bulge area, the comment about good tubes had to do with the ductility that the barrels showed. That characteristic would probably be lost around that area.
I hadn't noticed, in the pictures, a lifted rib or signs of cracks in the forearm wood either. It doesn't mean anything, but it might be supposed that this is not a 'ring' bulge.
