Well, after some searching, PT-ing and PM-ing, I found out that Tracks Double wedding band Oct. to Rd. barrel does have some taper on the Octagon part not much though, too bad TOTW's 42" Oct. to Rd. barrels all the same profile so a 24ga. barrel weighs 5 pounds and a 20ga. weighs 4 .25 Lbs. So after doing some more searching and calling around I bought a 42" Colerain Griffin profile barrel in 16ga. from Mr. Tip Curtis, came in today Btw, and it is a very nice barrel. I sent the 38" barrel back to MBS.
