Nice,video, See how the barrels are wired together & bent with wedges to regulate ? Thats why it’s so difficult to open chokes after a good double is regulated & the ribs are laid. Nothings straight to guide the reamer when opening, the reason you see out of round muzzles. If all open jobs were patterned to check regulation you would see many with different point of impact.
It’s not impossible to open chokes. but simply running a reamer in the bore piloted close to the choke taper is a good way to ruin a nice SXS . Factory single barrel gun it’s not a difficult job. All alike and straight.
