Most of the modern muzzleloader barrel makers offer swamped barrels, both rifled and smooth bore. I have never seen a swamped barrel profile on a breech loading shotgun but I did have a Paradox gun with swamped tubes. The thinnest spot on those barrels was maybe 10" behind the muzzles and it then became noticeably thicker towards the muzzles. I am sure that was done to get correct balance. Paradox gun with a Merriam's hen.

the most common use of swamped ribs is by the french. in my limited experience there seem to be as many french guns with swamped ribs as with "conventional" top & bottom ribs. i've never seen a MF without a swamped rib...and i have seen old MF literature reproduced on this site that tout the ribs as a superior design.
i find myself in agreement with that concept. rather than two separate strips with small bearing surfaces relative to the tubes, both top & bottom; a true swamped rib is one piece shaped roughly like an I-beam. installed at 3:00 & 9:00 between the tubes, this considerably increases the bearing surface available for securing the joints. and it also offers another clearly superior advantage - there is no gap inside the joined tubes. thus no place for hidden rust to begin acting on the structural strength of the barrel set.
question: who has ever seen a french swamped rib barrel that has separated from the rib? again my experience is limited, not that many french guns in my part of the country...but i have seen some beat to hell guns with the barrel sets intact and sound.
and on the subject of swamped barrels, burrard states that many light english game guns have thicker tubes at the muzzles than in the last 10-12 inches. the purpose being to strengthen the muzzles resistance to denting. we might be talking only a few thou increase - not visually apparent - but that is by definition "a swamped barrel".
best regards,
tom

Bill, using the logic used in the way you stated it, the purpose of a horse is to make horse shit. Yes, a horse makes dandy horse shit, but, the horse has other uses and purposes. There are multiple ways to achieve balance, involving the rib, or not.
I always thought the ugliest thing hung on a double gun was a tie, between beaver tail forend, and double beads.
Carry on.
Best,
Ted
Ted, I believe you missed the part in Bill's post where he refers to rifle barrels. I missed that part myself at first reading. He is quite correct when it comes to British rifles being balanced this way. I have owned several British rifles with barrels profiled this way. Steve I understood what he meant. The photo in the original post was clearly not a rifle. I have seen rifles with what is termed a duckbill rib. That is a different deal. Best, Ted

I communicated with Dr. Jim. The shipping record of the Eagle does not mention the rib. He has not seen the records of the 4 Crowns. SO I have no idea by what name Hunter Arms referred to the special order ribs. It appears the standard rib extension was used before "swamping" the rib  The rib in question  The usual rib
