Adding Rifling To A SxS

[nkbj]

Have any of you fellas added or had added a rifled liner to one barrel on a side by side?
Is it a practical matter, adding a liner to a barrel without pulling the breech?
No way I'm the first to contemplate changing an old 20 or 12 into a Cape gun configuration.
Who's looked into it?

That's an interesting idea, ask Bobby Hoyt if he can or recommends doing it.

Would need enough barrel thickness, most shotguns have thin barrels.

Thickness probably doesn’t matter is you’re inserting a liner.

Without unbreeching it I expect the problem would be in the breech. You might taper the end of the liner's bore so a jag wouldn't get hung, but the only right way to do it is to unbreech the barrels. A bore camera would give a better view of the breech situation.
