I haven't had it done yet, but I've priced it a couple of times. All of the prices I've seen were around $200-$250 to rebore the barrel, toss in an extra $50 or to rechamber it too. Honestly, unless it's an odd chambering or and old gun with a odd barrel contour, you can send it to ER Shaw and just get a new barrel installed (as long as it's a bolt action) for about the same price, maybe a bit more. Or, if you have a good hometown gunsmith that can do the work, you can buy a Shilen tube and get it chambered and installed for about the same perhaps.
