The only reason I ever had O/U barrels backbored was for weight reduction. Taking out .012-.014" removed nearly 5 ounces from a 32" set. The $400 at the time was worthwhile on a $3K clays gun. The people who do that kind of work are certainly capable but, at $200 per ounce I don't think I'd consider it on a SxS. I suppose you'd get chokes of your choice included in the cost, but I'd still consider another gun.
Think I'm with you Mike. The place doing the work has a couple of project Foxes available including a 16 gauge with 28" barrels. Might be able to pull off a trade. Mine was probably too nice for a project gun anyway. We will see what develops. PS. I've got an extra piece of Turkish that I don't need. There's lots of ways to skin a cat as they say.
