I have been following this thread, and have some interest in it as well. I have the opportunity to pick up a nice rook rifle that has been bore out to .410, like so many others.

Does anyone know if there are gunsmiths in the US that specialize in relining rook rifles to original calibers? I would guess gunsmiths familiar with these obsolete calibers are few and far between.
