Wayne,

Your question is a long way's from being dumb. Unfortunately the full answer would be a very in-depth discussion on machining practices. The short anwser for lining a barrel like this one appears to be done is.

1. To keep it the same gauge as original. The bore would need to bored/reamed oversized. Then a new liner machined to the new bore size though slightly O.D over sized and then press fit into the barrel & then finish bored for final I.D. diamensions & choke constrictions.

2. It would be easier to drop it down one or more gauge size. The reason it would be easier is you wouldn't need to bore the barrel wall thickness as thin, so you could retain the original gauge size. The liner could also have thicker walls as well & be an easier machining process. Please keep in mind though that no matter how this is done it is a very difficult & time consuming process that would cost lots of shop time this day and age.

Looking at the liners in this gun I suspect the material used was brass rather than bronze. I base this simply on the color of the liner. Brass is yellow toward gold in color. Bronze leans to more of a brownish color.

Bruce;
Are these full length liners on this gun? or are they just chamber and choke liners?
