A note concerning re-boring that I'll offer is that if you care about the aesthetics of your rifle you will want to handle the re-stamping of the new caliber yourself. Some reborers make quite a mess when it comes to re-marking, XXXXing out the old caliber and hand stamping the new. I milled a shallow groove which removed the original caliber marking and re-stamped it myself. Other options would be to have it laser marked or have your engraver handle the task.
