So here is the story. I am the new owner of a 1991 Pedersoli Classic SxS 12ga.(via trade not $$$) On close inspection now that it is mine, I discovered the bulges shown . Tried to get photos down the barrel but not much luck there. I have it in the hands of a gunsmith now who was somewhat mesmerized by the consistency, exactly matching locations and nearly exact sizes of these bulges.. the muzzlw photos show that some "welding" or "re-soldering has occurred so he is now researching to see if somewhere someone attmepted a "jugchoke" by somehow rolling a bulge into the barrels. Once he is done checking these bulges out, we will be either strapping it to a Lead Sled for test shots, or sawing the barrels back to clean bores. By the way the choke, IC&M I think. in both barrels is still there on the exit end of these bulges. Any and all comments are appreciated in advance.
