Thank you everyone for your replies. Maybe I wasn't clear when I wrote earlier, I did buy this Remington. Researcher, thanks also for doing the math. I just finished doing some cleaning and checking; here's what I found.
Right bore .733", choke .028" minimum wall .040"
Left bore .732", choke .037" minimum wall .039"
Gun weight is 7 pounds, 12.5 ounces
The bores are very good with only a little light tarnishing here and there. Its rib is pretty wide at a bit over 9/16" at the breech and 3/8" at the muzzles. I really like those C shaped hammers and how they come down below the plane of the breeches when cocked. Silvers
