To Address Craigd,
When JES did mine I asked they mark it under the barrel up by the action if they felt they needed to mark it as I have an engraver that I have do all my barrel markings when I have them done. They marked it under the barrel up by the action as requested and I had the two the did engraved where you would normally see the caliber. So the markings do not have to be Ugly and unlike a lined barrel there is no tell tail ring at the muzzle. I would not hesitate having them do a custom rifle or one of value if the bore was shot out.
