Lots of good info and perspectives! I rembember the first time I shot my Ithaca NID 16 with 1 1/8 oz of lead and the recoil sucked. I am not overly concerned about stretching the chambers 3/16" as I have no reason to overload... Mr. Roberts has expressed what I understand to be the general consensus pertaining to L.C. Smith fluid steel barrels and I'm comfortable with that. No I'll will or lawsuits but you will have the barrel walls accurately measured at some point so if I ever part with it, the next owner will know where things stand.
